First Indiglo 1993

VARTA battery leaked a bit in this one...
I was very lucky. I had left many of my dead batteries for years in my Quartz watches and I have ruined only one of maybe 90 such watches. A very nice SEIKO multifunction watch now needs a new movement 8M25 and so far I was not lucky enough to find one. But after I had seen that corroded 8M25 and what the battery did to it, I am removing a dead battery the moment I see the watch stop. If you look closely you see the discoloration from battery acid at the bottom of the battery compartment. This watch is luckily still running.

The movement is numbered M643-3 and there is a TMX stamp...
next to the coil (next to the battery compartment). If TIMEX would not have invented the Indiglo backlight (also called EL backlight, or electro-luminescent backlight), I would have said that this was just another China or Hong Kong Made Quartz movement. It seems this movement has been made for or by TIMEX exclusively. In other watches you will see that Timex also often used Citizen's Miyota movements.
