Battery Details

Do not confuse with these other batteries listed as "25"
PX25; LR57 (25, RW395/25).

This battery has been discontinued. The only thing I can find that comes close is the purpose made RW-25 Adapter from the Small Battery Company.

You could make a shim to take up the slack on an LR44 (see: Watch Battery Adapter page for ideas).

If you know differently, let me know.

Equivalents:
