It would have cost $24 per watch to have the jeweler replace the batteries so I figure this saved me $44! It was easy to do with my jewelry tools. ## Frequently Bought Together - Renata 364 SR621SW Batteries - 1.55V Silver Oxide 364 Watch Battery (100 Count) - Renata 377 SR626SW Batteries - 1.55V Silver Oxide 377 Watch Battery (100 Count) - Renata 371 SR920SW Batteries - 1.55V Silver Oxide 371 Watch Battery (100 Count) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/501116866-364-sr621sw-batteries-1-55v-silver-oxide-364-watch-battery](https://www.desertcart.hr/products/501116866-364-sr621sw-batteries-1-55v-silver-oxide-364-watch-battery) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-24*
