Energizer 377 1.5 volt silver

Popped one into my vintage watch that had been dead for years and it started ticking instantly. The voltage is steady so the second hand sweeps smooth, not jerky like with cheaper cells.

These little cells fit my watch perfectly and the 1.55 volt rating means the timekeeping stays spot-on. I've had the same one in for over a year now, and it's still ticking without a single hiccup.

These little 377s have powered my watch reliably for over a year now, and I was glad to find the exact voltage replacement I needed. The 1.55 volt output is spot on for the LR44 equivalent I was searching for.
