What it fits
Small analog watches. Confirm the printed number or measure the old cell before you buy — a 0.5 mm height difference will not seat correctly.
IEC names encode chemistry and size. SR is silver oxide, LR is alkaline, and CR is 3 V lithium. The digits are diameter and height in tenths of a millimeter, so SR527SW is about 5.8 mm across and 2.7 mm thick.
