5/5 stars - reliable silver oxide cells for accurate everyday watch operation
I selected these silver oxide cells to service several quartz watches where voltage stability and predictable discharge curves are more important than headline capacity. In practical use, the 377 specification delivers consistent 1.5 V output, which is critical for maintaining accuracy in small analogue movements. Installation is straightforward, the dimensions are precise, and contact reliability has been good across multiple case designs. This reflects the majority of user feedback noting proper fit and immediate functionality without intermittent dropouts. From a technical perspective, silver oxide chemistry remains the correct choice for watches due to its flatter discharge profile compared with alkaline alternatives. Longevity has been acceptable in real-world use, though a minority of reports suggest shorter life in high-drain or older movements, which is more likely movement-related than a cell defect. Packaging is sensible for consumers who want quality without excessive surplus. At the current price, it avoids unnecessary jeweller visits while maintaining dependable performance.

Great value and longevity.
Being retired I thought I would search the house for all the watches that had been left in drawers, it's better value for money as opposed to taking them to a watchmaker. My personal preference is Duracell mainly for battery life

I destroyed my watch back cover chanching battery's. The watch worked fine itself with the new battery so i would go for the 5 stars instant. Its nice to buy a decent battery instead of a 10 pack you trow away.
