Original product.
I usually read the bad reviews before buying but I say, let’s try. Original product, arrived by mail but in good condition. Installed in my watch (Mido) and worked perfectly. I surely buy again from this seller.

Identical Replacement to the OEM Tissot Battery
My Tissot Supersport Chronograph used this same Renata Swiss battery. Identical Replacement. Swiss battery for a Swiss watch. Works great. The expiration date was 2 years from now, so the seller is shipping new batteries. A+. I will update my review if anything changes or if the battery life is not as long as expected.

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.
