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.

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.
