Hi to all. When I put the batteries to my pulsar in the display I only can read
" : " or "1 : ".
Sombody knows how can I repair it?
Can you indicate me what quartz crystal (type in hz) has this watch?
Thank you very much

All Time Computer watches, from the very beginning, used quartz crystals oscillating at 32,768 Hz [32KHz]. There were many different crystal package types, tending to get smaller as the watch designs got more advanced and refined. The Dress models typically used the 3x9 mm cylindrical packages [usually gold-colored]. Swapping out a crystal from another module is not a complex or time-consuming repair. The module in the Dress watch is identical in all resprects to the one in the Ladis' models, with the exception of the LED display itself; the digits are about 1mm taller on the Dress version [but the quartz crystals will interchange].
