Page 1 of 1Reliable 399 Watch Battery Replacements
A 399 watch battery is a compact 1.55V silver oxide cell used in many analogue watches, chronographs and small precision devices. In this category you can find compatible options such as SR927SW, SR927W, Duracell D399 and Varta 399, selected for stable voltage, dependable performance and accurate timekeeping.
Whether you are replacing a battery in an everyday wristwatch or servicing a more delicate timepiece, choosing the correct size and chemistry is important. The 399 format is designed to deliver consistent power in a very small case, helping your watch movement run smoothly until the next replacement interval.
What Does 399 / SR927SW / SR927W Mean?
The codes printed on watch batteries can look confusing, but they usually describe the same physical format and chemistry. 399 is a common reference number, while SR927SW and SR927W are technical designations used by battery manufacturers. These cells are typically silver oxide batteries with a nominal voltage of 1.55V.
The letters can indicate discharge characteristics. SR927SW is often intended for low-drain watch movements, while SR927W can be suitable for watches that may require slightly higher pulse capability, such as models with additional functions. Always check the marking on your old battery or the watch manual before ordering.

How to Choose the Right 399 Battery
Before replacing your watch battery, compare the code, diameter and height of the old cell. The 399 watch battery family is commonly associated with the SR927 size, but different devices may require a specific variant. If the old cell is marked D399, V399, SR927SW or SR927W, the products in this category are designed to help you find a suitable replacement.
- Open the watch carefully or ask a watch specialist if the case is sealed.
- Read the exact code on the existing battery.
- Match the code to a 399, SR927SW or SR927W replacement.
- Install the new cell without touching both battery surfaces with bare fingers.
- Check that the watch starts and the case back is closed securely.
Tip: If your watch stops again shortly after battery replacement, the movement may need cleaning or inspection rather than another battery.
