Works great
Same battery as the original watch battery. Works great. One odd note. Amazon sent this tiny battery in huge 11x17 or larger envelope. Waste of packaging.

Replacement Batteries for an older MK watch
The 2 battery pack that arrived seemed to be hand-cut from a larger blister pack so I have no info on the expiration date of the batteries. Installed battery and it works.

Die Renata 364 ist die ideale Wahl für jeden, der eine hochwertige Armbanduhr (z. B. von Marken wie Tissot, Longines oder Swatch selbst) besitzt. Der Aufpreis von wenigen Cent im Vergleich zu Billigbatterien lohnt sich fast immer, da ein Auslaufen der Batterie das Uhrwerk irreparabel beschädigen könnte.
