Al - on a previous post I recall you saying you now use Maxcell cells when doing replacements instead of Renta cells. Can you tell the Maxcell model code for the correct cell for the 1538 cal used in the SMPq? Regards
What is the case reference or serial number of the watch - sometimes the battery thickness depends on the case.
Okay the traditional number for this would be a 395 if you were going Renata, and in the Japanese system that is an SR927SW. Cheers, Al
