Great watch battery
I saved a ton of money by replacing my watch batteries myself. It would have cost $24 per watch to have the jeweler replace the batteries so I figure this saved me $44! It was easy to do with my jewelry tools.

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.
