I have a Seiko 6m26A watch in which no one stepper motor works.
When I set the stopwatch function, after pressing the start and reset pushers, a beep sounds.
It even rings the alarm signal at the time stored in the processor.
Unfortunately, regardless of the function selected, the right beeps are heard, but all the hands and date are dead.
Inside the case everything seemed to be complete.
I unscrewed it and washed the connection and electronics boards.
I did a hard reset (after changing the battery) and soft reset (clock reset using pushers).
Nothing but beeps.
Maybe someone can tell where to look for a fault in this system?
