This is a 22-pack of Murata 379 cells, also known as SR521SW.

They’re silver oxide, so they last longer than the cheap alkaline ones.

Replaces Sony 379 and fits watches, calculators, small electronics, you name it.

Brand new, fresh stock, no UPC on the pack.

Keep a few in your drawer so you’re not stuck with a dead watch right before a meeting.
