Hello list,
I am restoring a Seiko Quartz QM10 Marine Chronometer that is currently
inoperative. Preliminary investigations would indicate that the
oscillator (TO5 header) isn't functioning therefore I am seeking any
information as to its nominal frequency and whether it is just a crystal
or an oscillator. I can follow the cmos dividers OK but a schematic
diagram would be most useful.
Any help or pointers much appreciated.
Kind regards
Peter UK
