This battery is unavailable now. I have found the number referenced on a Chinese website but I couldn't get any details from there that I could understand! If anyone has further data on this battery please email me and I'll update this page.
It may be possible to stack 2 LR62 to get the thickness, near width and voltage, and then make a spacer from foil to take up the slack for the length. Make sure that the spacer doesn't short out the series connection though (some tape will suffice).
The photos on this page were kindly submitted via email by a visitor who found this page while trying to replace the dead battery in his watch. Many thanks Steve.
