Casio Illuminator MTD-1049

After having recovered from the jet lag traveling to the
PMWFerence 06 ...
my vision returned to a point where I could spot a fog like film on the
inside of the crystal. Great! I had now a reason to disassemble the watch. I
love that as much as I love wearing them. Trying to see what is inside and how
watches are built was always as fascinating as their designs.
Be careful: the top LED fell out when disassembling
the watch. The two LEDs feet are mounted between two contact springs. Those are
only visible with a loupe. When I first assembled this watch, the 12 o'clock LED
was not always making good contact. So I had to disassemble the watch again and
discovered that the LED feet have to be inserted between two tiny springs on the
circuit board. The rest of the assembly is fairly straight forward, although the
spring load of the battery (CR2016) holder is quite stiff and requires a
confident push down on the battery when re-inserting.
