329 SR731SW Watch Batteries 1.55V

Reliable 329 watch battery for precise timekeeping

The 329 watch battery, also known as SR731SW or Varta V329, is a compact 1.55V silver oxide cell designed for selected wristwatches and small precision electronics. Its stable voltage output helps quartz movements keep accurate time, while the trusted Varta manufacturing quality makes it a dependable choice for battery replacement.

This category includes compatible Varta 329 SR731SW 1.55V batteries for customers who need a genuine replacement cell with the correct size, chemistry and voltage. If your old battery is marked 329, SR731SW, SR731, V329 or an equivalent reference, this is the right place to find a suitable option.

Why choose a silver oxide SR731SW battery?

Unlike many alkaline button cells, a silver oxide watch battery is engineered to deliver a more consistent voltage throughout its service life. This is especially important for analogue and digital watches, where stable power supports accurate movement operation and reliable display performance. The 1.55V 329 battery is typically used in low-drain devices, making it ideal for watches that require long-lasting, steady energy rather than short bursts of high current.

Common names and equivalents

Watch battery codes can be confusing because different brands and catalogues use different labels for the same cell size. When shopping for a replacement, check the marking on your existing battery or your watch manual. The 329 battery is commonly associated with the following references:

• 329 watch battery
• SR731SW silver oxide battery
• SR731 button cell reference
• Varta V329 1.55V cell

If these markings match your old battery, you can confidently select a product from this category. If your watch uses a different code, always compare the diameter, height, voltage and chemistry before installation.

Tips before replacing your watch battery

1. Confirm the battery code: Read the number printed on the old cell before ordering.
2. Use the correct chemistry: Choose silver oxide SR731SW when the device requires stable 1.55V output.
3. Handle carefully: Avoid touching both sides of the cell with bare fingers, as oil and moisture may affect contact quality.
4. Check polarity: Insert the new 329 battery in the same orientation as the old one.

A precisely matched watch battery helps protect the movement and ensures dependable everyday performance.
