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.

Exactement la même marque de pile avec les mêmes caractéristiques que celle d'origine de ma montre. Pour l'instant tout fonctionne très bien ! Devrait tenir au moins deux ans !
