This watch is not for the faint-hearted. It weighs in at 152 grams, and that’s quite a lot for a quartz watch. The width including crown and pushers is 51.3mm!
The crown has three positions. Pushed in closes a contact (pin above the winding stem) which advances the movement slowly by moving the motor constantly. In normal position, nothing happens, and in pulled out position, the watch can be advanced one hour at a time, which is also used to set the date.
The movement back in the case. The chronograph in normal mode shows minutes at the top and seconds at the bottom. If the middle button is pressed, the display changes to hours at the top and 1/100s at the bottom.
A look at the electronics. All hand-soldered, and the two batteries are big enough to jump-start your car. The are connected in line, so the movement uses 3V. The quartz is at the top left (white plastic back), below that the poti for adjusting the beat rate, the IC to the left of that, and the brass coloured round thing with the red “CE” stamped on it is the step motor.
Back to working condition. Before you wear this watch, you have to do some working out at the gym!
