Cell types in this size

SR416SW

Low drain (SW): for plain analog watches · Silver Oxide2

6 codes in our sources name this cell type.

LR416

Alkaline cell of the same size: the IEC digits are the size, the L is the chemistry. LR416 lands on this page by that rule; our sources hold no alkaline datasheet for it, so no figures are shown.

  • Use instead of SR416SW

    LR416

    Fits, with a catch

    Fits, but LR416 is alkaline and runs shorter.

    Same 4.8 mm × 1.65 mm size. LR416 is an alkaline (L) cell; the watch is made for silver oxide (S). Use it to get the watch going, then fit SR416SW.

Questions

What is the 337 battery equivalent?

SR416SW, V337, 623, 280-75, SB-A5, SR416 name the same 4.8 × 1.65 mm silver oxide cell as 337. Any maker's cell under one of these codes fits.

Is LR416 the same as SR416SW?

No: LR416 is an alkaline cell of the same size, SR416SW is silver oxide. Fits, but LR416 is alkaline and runs shorter. Same 4.8 mm × 1.65 mm size. LR416 is an alkaline (L) cell; the watch is made for silver oxide (S). Use it to get the watch going, then fit SR416SW.

What watches use the 337 battery?

In our base: 2 Seiko calibres (1F20, Y150…). The full lists are on this page, with the brand tables they come from.
