⭐️⭐️⭐️⭐️⭐️ Excellent Quality – Reliable Swiss Watch Batteries
I’ve used Renata watch batteries for years and these 379 (SR521SW) cells fully live up to their reputation. They’re Swiss-made, high quality, and provide consistent, long-lasting power. I fitted one to my watch and it started instantly, keeping perfect time with no issues. The pack of 10 is excellent value, especially compared to buying single batteries locally. Each battery arrived well packaged and clearly marked, so there’s no confusion when storing spares. If you want dependable, genuine watch batteries from a trusted brand, you really can’t go wrong with Renata. Highly recommended.
