Lasts over 2 years
Had to buy a second battery 2 years later. I have an omega swatch as a my daily wear and works perfectly in that model.

Great Watch Battery!
I finally decided to start changing out my watch batteries myself. Why pay $20 plus from a jewelry shop when I can do it myself. I bought the watch repair kit and this battery. It took just a few minutes to replace the battery with this one. Works perfectly! I will be purchasing this battery again!

Perfect fit.
Perfect battery for a old watch that needed to be put back in my weekly rotation.

My Battery finally arrived!
Bought this battery for my watch, good value at $2.12. It took two weeks to arrive in a letter type envelope, no padding around the battery. Was kinda surprised on that but it made it, that's what's important. Hopefully it works!

Battery dead on arrival
I would give this a zero if possible. I put this battery in my swatch watch and it didn’t work. I tested the battery life with a tester and the battery was dead. Never again will I order from this seller.

Ottima per il mio orologio Tissot
Perfetta per il ricambio del mio Tissot, senza andare dal orologiaio, funziona bene.

Hard to find battery works!
It was mailed to me via regular mail from Quebec. This hard to find locally battery worked to revive my almost 22 year old Swatch and I'm pretty happy about that. The expiry date on the package is October 2027 (it is now November 2025). Fingers-crossed the battery lasts at least that long.
