Every watch cell, to scale

All 45 sizes drawn at one scale, grouped by diameter: cells in a group share a diameter and differ in height or chemistry. Face above, edge below; tap a cell for its page.

Questions

What is the most common watch battery?

In our base it is MT621: 492 calibres, modules and models name it. Next come CR2016 (365) and SR621SW (364) (194).

What do SW and W mean on a watch battery?

Both are silver oxide cells of the same size. SW marks the low-drain cell for plain analog watches; W marks the high-drain cell for watches with lights, alarms or chronographs. 6 of our sizes come in both, among them SR626SW and SR626W, SR916SW and SR916W, SR920SW and SR920W, SR927SW and SR927W.

Can I use a lithium CR battery instead of a silver oxide one?

No. A lithium coin cell such as CR2016 is 3 V; a silver oxide cell such as SR626SW is 1.55 V. The voltage alone rules the swap out, whatever the size.

Voltages: CR2016[11], SR626SW[2]

Which watch batteries are rechargeable?

Solar and kinetic watches hold a rechargeable cell, not a battery to swap for any primary one. Of our sizes, 7 are rechargeable: MT516F, CTL621F, MT621, CTL920F, MT920, TS920E, CTL1616F. Replace them only with the same type.
