When do you need a silver oxide watch battery?
Silver oxide batteries such as the V329 are specifically designed for small electronic devices such as watches, calculators and medical devices. You need this battery when your original watch battery is flat and your device stops working. The constant 1.55V voltage ensures that your watch keeps running accurately until the battery is completely depleted.

Why choose the V329 variant?
This battery measures 7.9×3.1 mm and fits watches that are compatible with the SR731SW or 329 reference. Always check the old battery or your watch manual for the correct type designation. With a capacity of 37 mAh, this battery provides sufficient energy for long-lasting use in standard analogue and digital watches.

Silver oxide technology for reliability
Silver oxide batteries outperform alkaline alternatives because they deliver a stable voltage throughout their entire lifespan. This V329 holds the 1.55V consistently, which is important for the accuracy of your timepiece. The technology is also less sensitive to temperature fluctuations than cheaper battery types.

Practical installation tip
When replacing, pay attention to the correct polarity – the positive side of the battery must face the right way. Use plastic tweezers or a coin to insert the battery and avoid touching it with your fingers to prevent corrosion. Store spare batteries dry and at room temperature for optimal shelf life.
