Watch Battery Cross Reference Chart | Renata & Brand Equivalents

Looking for a reliable watch battery cross reference chart? This comprehensive conversion table helps you quickly identify equivalent silver oxide batteries across major brands such as Renata, Duracell, Energizer (Eveready), Maxell, Varta, Timex, Bulova, Seiko, Citizen, and Rayovac. Whether you’re a watch enthusiast, a repair professional, or simply replacing the cell in your quartz watch, this guide makes it easy to find the right battery every time.

Watch batteries often carry different reference numbers depending on the manufacturer, but the underlying IEC codes and dimensions (diameter × height in millimeters) are standardized. Using our chart, you can match a Renata 357, for example, to its exact equivalent in other brands, ensuring proper fit and performance. The table also lists application types (High Drain, Low Drain, or General), so you can choose the correct cell for chronographs, digital watches, or standard analog models.

This cross reference list covers the most commonly used silver oxide watch battery types, including popular sizes like SR44SW / 303, SR920SW / 371, SR626SW / 377, SR927SW / 399, and many more. Each entry includes Renata’s part number, IEC code, physical size, and equivalents from other major battery makers, all neatly organized in a sortable, responsive HTML table.

Bookmark this page as your go-to watch battery conversion chart to save time during battery replacements, reduce errors, and improve your workflow.
