Awesome watch if you're not looking for anything over the top
This watch is perfect for my needs. I run but not marathons. I lift but I'm not a bodybuilder. There are options to track almost any kind of workout you can think of. It tracks steps and sleep and pulse automatically. The GPS is accurate and consistent. This is a great watch for people who take care of themselves but aren't fanatics about it andb especially if they like to charge things up. The watch can do much more than what I have listed below, but here's what stands out to me: Pros: -built IN HR monitor -workout mode: choose from run, treadmill, bike, walk, cardio, or add your own activity -the app allows you to add workouts you didn't track on the watch, e.g., yoga, etc. -Not too big, not too small -choose from different watch faces -choose which widgets the watch displays and in what order (weather, smart notifications, steps, etc.) -smart notifications from your phone (if you're into that) -you can calibrate it if you're using a treadmill (for example, you run 5 miles on the treadmill, but the watch estimates 3.8. Before you save the workout, you can adjust the distance to match the treadmill display. If you forget to do it before you save it on the watch, you can do it later in the app, though the data will not adjust and you'll end up with the correct distance but a big black spot at the end). This is a manual adjustment - you don't need any special Bluetooth enabled treadmill or anything like that. Cons: -face has somewhat small print, certain displays can be hard to read -body battery is inconsistent. It's just a made up thing anyway so not a big deal but doesn't seem to make sense. A good night of sleep should "charge your battery" but often the nights I feel most rested it tells me that my battery is very low. -watch battery doesn't seem to have a warning. I occasionally forget to charge it and don't remember until it's completely dead and the watch is off. Would be nice to get a low battery warning.

Great watch for outdoor running
My usual fitness activities have been curtailed by the pandemic, so I started running again. I wanted a device with GPS tracking so I could figure out how far I was running and at what pace. The Forerunner 45 does everything I need, some things that are informative that I didn't know I wanted, and a whole bunch of stuff I don't actually care about. The watch does a great job of tracking distance and time. It continuously records heart rate and steps, so you can see how your pace and run cadence (steps per minute) change over the course of the run. The data is transferred to a mobile device over Bluetooth and then uploaded to the cloud, so you can sit at your computer afterward and see an interactive map of the route you took. This allows you to see if you're speeding up or slowing down at different points. (You can see stats like current pace and heart rate on the watch itself while you're running, but I prefer the after-action report approach.) Most of the data is more interesting than useful, but the important parts seem pretty solid. The watch itself is easy to use. Unlike most mobile devices, it's actually easier to read in bright sunlight. There's about a billion different things you can configure, but if you don't care about those things you can just ignore them. The Bluetooth connectivity works well with my low-end Motorola phone, often sending me notifications even when I'm upstairs and the phone is downstairs. (It's got a lot of "smart watch" features, showing incoming e-mail, text messages, etc.) The watch is waterproof, but the manual recommends rinsing it off if after a workout to prevent corrosion. The Garmin Connect software has all sorts of coaching and social media blah blah whatever. If you want to share or compete you can do so. You can specify the type of exercise you're doing, so I started tracking dog walks as well. Overall, after using it for a week, it seems to be a pretty good piece of gear.

High quality item, high quality service
Cons: Battery life. There is supposedly a setting to prevent constant updating by Bluetooth to increase battery life, but I can't find it. Features may be too limited for some tastes. Pros: Intuitive controls, durable, easy to read, has all the features necessary for a run watch and then some. I just wanted a watch to track my heart rate, with GPS to track my runs. After much study, I originally purchased a Fitbit. This was perfect for me until 30 days after the warranty ended, and firmware was automatically upgraded improperly. The watch stopped working. As I was out of warranty, no help available. In Feb 2024, I purchased the Garmin Forerunner 45. I was immediately struck by the much higher quality and ease of controls. This watch does what I need and more. I can easily track kilometers run, meters climbed, heart rate, and pace. Or you can change it to feet and miles, if you prefer. I can look at my watch to read texts and decide if they need an immediate answer (rarely!). In late May 2025 (2 months out of warranty), the tiny bracket that holds the band to the watch itself broke, and is unrepairable. Remembering the other brand, I was not happy. But I contacted Garmin, sent a picture of the damage, and received a no charge replacement. I...did not expect that. I expected to get nothing, but would have been very happy to get a 50% discount on a refurbished model. Nope. Free, and brand new, and Garmin even paid for shipping. As someone who has been dealing with warranties for decades as a consumer AND a service provider, I am ecstatic. Garmin has a customer for life!

Still a fantastic watch
I have used tracking devices since 2008. Three garmins, 2 fibits and withings and xiaomi and amazfit. This one is still in the lead. It has the most accurate built in readiness score, the best stress measure with heart rate variability, and Vo2 max. It does everything. And the app is completely free and chock full of information. One the neatest features is having a place to track the shoes you are wearing and the miles you have in them. Because changing out your shoes protects you from pronating, heavy heel strike, and developing postural distortions and back pain. I keep a Fitbit premium membership for the meditations and coached workouts. Garmin app communicates with Fitbit transferring data using google health app. Touch screens are overrated. Buttons are fantastic. And this garmin also has fall protection and detection and will call for help if you are in a car wreck or fall down a mountainside. While you are unconscious your watch will call for help with your location. Trackers almost equivalent to this are Pixel 2 and Fitbit sensor 2.

Everything I needed, and more
Given the proliferation of fitness trackers these days, it was difficult deciding which one to get. My primary requirements : 1. accurate heart rate monitor (walking, running biking. Not planning to wear it while swimming). Accuracy is important to ensure maintaining correct heart rate depending on the goal eg fat burn vs cardio. 2. accurate standalone GPS to measure distances 3. decent step counter 4. buttons, not touchscreen (to be able to operate by touch eg while biking). Buttons feel solid. 5. able to provide almost all functionality without requiring a smartphone or app ( privacy) this is the review after wearing the FR45 almost continuously for 4 weeks, only taking it off while showering or charging. the FR45 meets all these requirements. the Garmin Connect has a windows application, which can sync directly with the watch over USB. it does require setting up an account with an email address, but no other information is gathered. I am able to use this app to view historical data, trends etc without having to use the smartphone app. Additional benefits: 1. the sleep monitor is surprisingly accurate, and somewhat eye-opening in terms of understanding the sleep cycle every night. I think it can drive better sleeping habits 2. stated battery life is 7 days without using GPS. I'm able to get about 6 days, using GPS for about 2-3 hours during that period 3. If one is so inclined, your profile can be connected to apps like MyFitnessPal to track your calorie intake and get a view of overall calorie input and output. I don't use it 4. the Stress and 'Body battery' indicators are fun to see (not sure how accurate/useful) 5. you can participate in group activities, challenges etc 6. you can track all useful information (distance, HR, stress level, calories, steps etc) easily on the watch itself, though it might be somewhat small to look at 7. display works well in most situations, even direct sunlight. there is a backlight button, for very lowlight situations 8. Garmin Connect windows app provides a very nice clean interface, and a helpful dashboard to be able to see daily and historical info and trends. there is a lot more in there that I'm not using at this time. 9. looks nice. Others have reporting issues with the wristband, i did feel a bit of itching and irritation in the beginning, probably because i wore to too tight, but am able to adjust to it by switching wrists daily and not wearing it too tightly. Some things that could be better: 1. the heart rate counter has trouble keeping up with rapid changes. for eg, if I go from walking to running on the treadmill, the watch takes anywhere from 30s to 2 mins to catch up with the new HR. Same with slowing down. This is probably the biggest issue I've faced, but can get used to it. when it does catch up though, its accurate to within 1-2 heartbeats (compared with finger oximeter, treadmill monitor) 2. GPS can sometimes take frustratingly long to get active. Syncing frequently seems to solve this issue (i only sync with the laptop once every 5-6 days, so maybe this might be just a problem for me 3. step tracker is a bit iffy, I'll usually wake up on the morning with about 100-200 steps in the counter (basically arm movements seem to trigger it). brushing teeth can also give you some steps :) not a big issue, just discount about 400-500 steps from your daily count to account for these conditions. Overall, I'm very satisfied with this purchase, and feels like this would be solid performer for years to come, or at least until the battery gives out.

Easy to use for runners and walkers
I am not an olympic athlete. All I needed was something that would help me track mileage and heart rate and could be easily programmed. This watch fits the bill perfectly. While the display is not super fancy with 1000 different faces with neon bar graphs and dials, it does the job and it does it well. I use the watch mainly for running. The watch, along with the app, allows me to track all of the important data I need such as heart rate, pace, distance, stride, etc. I train using heart rate zones, and after setting your personal zones, each workout can be tailored to your heart rate. For instance, sometimes I do long easy runs in Zone 2 and sometimes I do intervals in zones 2 and 4 and sometimes I just do a short zone 3. All of these are easily programmed via the app and the watch will beep and vibrate when you are out of your target zone. The same alerts can be set for pace, distance, etc. The watch does have some other features like connecting to Spotify but I don't bother with those. I can verify that you can wear it in the pool. I foolishly decided to see if I could swim 100 meters and while my body couldn't handle it, the watch could. If you are looking for an affordable running watch, this is it.

A dear, dear friend
How do we know how much we love someone or something? By how much/how little we rejoice when being reunited. Back in August 21', my Garmin Forerunner 230--my second watch of that model--broke when I slipped on a pothole during a long distance run in Jerusalem. Because I wear the face of the watch on the under wrist, it broke while I was breaking my fall. I loved this watch, even though it was an older model that had been phased out of production, and I purchased both it and the previous unit as "refurbished" watches on Amazon. I wore this watch in tandem with a Garmin chest strap to get the most accurate heart rate reading I could during these long runs. When the watch broke, I didn't bother ordering a new one, as I was overseas and preferred to wait until I would be back home in the USA in couple of months. While I missed not having a watch to measure the distances and paces of my runs, I felt a certain "release" and freedom to run without the compulsion to always look down at my watch to see how many miles were behind me, or what my running pace was. I felt free to simply "be in the moment" and enjoy the scenery without defining the moment by my live stats... ...Until four months later, when I started to miss my Garmin. I was going to look for another outdated, refurbished Forerunner 230, but when I looked for it on the Amazon site, I kept being directed to a new Forerunner 45 instead. The display was very different from the 230, and as I read about its features, I thought it has too many "bells and whistles" that I don't need....like the "body battery" feature, concerning which I was quite cynical as to how accurate such a feature could really be (similar to my cynicism about my previous watch's claim to be able to measure my VO2 max). Notwithstanding, at only $139, I considered the watch a great value and purchased it. Just one week into wearing it, I can't take it off...I'm addicted to it! The most pleasant surprise has been the accuracy and convenience of the built in heart rate monitor, which over the past three long distance runs has proven itself to be every bit as good and accurate as the Garmin chest strap I formally wore with the 230. Now I have around-the-clock, 24 hour heart readings, including my resting heart beat, which again is very accurate (mind you, I wear the watch with the face on the under wrist, which probably provides for a more accurate pulse reading). And the feature I was most cynical about, the "body battery," has also proven itself a delightful and accurate edition to the repertoire of my watch's features. How do I know it is accurate? Simply because it accurately expresses exactly how I feel! It is really amazing. Even the clock display, which I thought I would never grow to like--it displays the minutes beneath the hours--has grown on me in just a week, and no longer bothers me. Whereas I used to take off my other Garmins when I went to bed, as they didn't have any features I felt I need during the night, the 45 model begs to be worn around-the-clock, as it provides vital information--heart rate, sleep, and body clock summaries--the next morning. With these features, especially the "body battery," the watch is tutoring me as to what my realistic fitness aims should be, on a particular day. If the body battery displays a 25/100 charge, I probably shouldn't attempt a 12 mile run, like I did nonetheless yesterday, I failed to complete it before hitting "the wall." I highly recommend this watch an model, which is becoming a dear, dear friend.

Super quick GPS tracking, Nice watch face
Firstly, Amazon Prime is great. This watch came in good time as a Father's Day from my sons to me. As for the product, it is great. Maybe I am a Garmin watch user all this while so I am quite used to the menu and the buttons. The GPS tracking is great. It can track within 10 seconds compared to the Forerunner 220 which can take several minutes. And this watch has the heart rate monitoring and steps counter. All in one. The clock faces also gave us a variety of choices to choose from. The bad thing is that the there are only two data fields for the custom data screen. Should provide 3.

Outstandingly Engineered
I’ve waited for five months before writing a review on the Garmin Forerunner 45. I wanted to be sure of my views and that confidence could only emerge with repeated usage over time. Hence, after about more or less 500kms of running in the past five months, I am confident of my review accuracy. So I wanted a fitness watch, solely to monitor my runs, walks and physical activity. It took me some time but I homed on to the Forerunner 45 considering both my budget and specific purpose. The Forerunner 45 is not a smart watch with versatility and functions of the Apple Watch but it performs some useful smart functions of alerting you once a call or message is received. Leave that aside as my purpose was not a full-scale smart watch but a physical fitness smart watch. And I could not have been happier. The Forerunner 45 is beautifully crafted and ergonomically designed. I have a thin wrist and the watch size was perfect for me. I find it fits snugly and the watch band has excellent grip and sturdy latching mechanism. It is very accurate. I matched the iPhone measurements and based on my previous measured runs I found the watch to be consistent and correct in measurements. Plus, it’s a Garmin product, they produce GPS receivers that are fitted on aircraft and ships the world over. So accuracy is assured. Battery life is very good, I need to charge it every third day or preferably the second day, and the charging takes little time. I think about 30 minutes or so to full charge from half charge status. In all probability, if you don’t use the GPS, the battery life will be a week. The point is battery life is very good and charges fast. The push buttons for accessing the menu are intuitive and I never felt the need for a touch screen functionality. When your fingers are sweaty and you are doused in sweat, you need hard interfaces and the push buttons are ideal. At least I feel so. The menu navigation takes a little time to get used to but it’s not a worry at all. Be a little patient in the initial stages to learn the settings. There is some complexity in settings such as alerts every km or units or targets etc. I wonder how much of these can one gainfully use, but there are a number of user settings that can be done. I like the feature that when it’s dark and you are exercising, the dial lights up when the wrist is turned to your face for you to see the exercise status, and then switches off on its own. That saves battery too. Good engineering. Yes, you may have read that the GPS lock on takes some time and I too have noted that occasionally. But off late, after upgrading the software, I have not noticed any delay in locking on to the GPS. It takes less than a minute but I have had occasions that the lock on has taken up to 15 minutes. In a way, a few minutes to achieve lock on is good as I warm up and stretch during that time. So if it takes a little while, I am fine with it. But please ensure that you upgrade the software upon release of a new version. This should happen automatically on syncing the watch with the Garmin App on the phone. The mobile app is well designed and syncs well with the watch. The details of your walk, run, duration of exercises, VO2, calories, sleep activity are all updated and aggregated. For instance, it’s a good feeling to see the amount you’ve walked or run in a week or a month or a full year. And you do get motivated to exercise more if the data shows a declining trend. Your best effort is also highlighted from time to time. In all, the Garmin app is neat, well designed and presents the data in great detail. For example, you can access additional details of your run, your heart rate, body battery and also stress level. You can compare yourself with the rest of the population that is using Garmin app. Frankly, I have not accessed in great detail the data measured by the Watch, its quite a lot. But the watch is very sensitive. I was once running and a wire from a tree was hanging loose, I ran into it unknowingly and it stabbed me on my cheek bone...I stopped dead on my track and the watch started to vibrate wildly exclaiming a sudden stop and then went on to dial the emergency number. I was amazed. This could have actually been an emergency if the wire has impacted my eye. Hence, the watch is very sensitive to alert any fall or sudden stop. I can vouch for that. So for QUALITY, BUILD, ACCURACY, APP SUPPORT and BATTERY...the Forerunner 45 is a great fitness watch.

Great Basic GPS Watch
I purchased this watch to replace a Garmin Forerunner 35 that I had for years as it was on it's last legs. I found this watch to be easy to add to the Gamin Connect app so I could seamlessly keep using that for my workouts and other data. I especially like the GPS feature so I can just go for a run anywhere I want and I know how far I have gone. This eliminates the need to carry my phone or repeatedly run the same pre measured routes. This Forerunner 45 is about the least expensive sports watch I could find that had the built in GPS. I find the distance tracking to be quite accurate based on using it on known routes that had distance measured previously. The battery life is excellent and it can go for a number of days without recharging. However, one of the minor issues I have with this watch over the 35 is that I have to take it off to charge it as the charger plugs into the back. With the 35, the charger kind of clipped on the side so I could continue wearing it while charging. I typically charged it when working by simply plugging it into my laptop. The Forerunner 45 was also easy to pair with my phone and gives me notifications for emails, texts, incoming calls, etc. However, I do find the display on this watch a bit harder to read than the 35. There is more info to see and the text is smaller on this watch. But, I am on the older side, so any younger users with better eyesight may not have any issues with this. Overall, this is an excellent, basic, fitness and smart watch. And with the built in GPS at this price level, it can't be beat.

Muy buen reloj de entrada
Excelente reloj de entrada, es super ligero, solo no me gustó que es un poco pequeño (42 mm), en las fotos la perspectiva es que es más grande. Pero en cuanto a funcionalidad es bastante bueno. puedes configurar tus entrenamientos por día, se conecta rápidamente por medio del BlueTooh y la precisión del GPS bastante buena hasta el momento.
