Question about Seiko 0512037FA Wrist Watch
PLEASE SEE IF YOU CAN HELP ME WITH THIS PROBLEM.
I JUST PURCHASED A SEIKOSNA619, THE STOP WATCH HAND ONLY RESETS AT 23 MINUTES AFTER,I TRIED TO RECALIBRATE BUT WHEN I PULL THE CROWN ALL THE WAY OUT IT EITHER RESETS AT 23 AFTER OR NOT AT ALL.ALSOBRING WHEN I PULL THE CROWN THE HAND IN UESTION DOES NOT MOVE,THEREFORE I AM NOT ABLE TO SET IT AT THE 12 POSITION.
DOMENIC IN PA.
I guess the blue faced SEIKO is a Flightmaster (Model: 7T92- OCFO)and it is a great watch. This is a common problem with most chronographs and this happens due to misalignment with usage.
All you need to do is pull out the locking crown all the way out (2nd Step) as if setting time. and then press and hold the top / left button and at first the milli seconds hand resets. after which you have to press the borrom / right button to move the seconds hand in to place. and then reset the time and lock the crown. You can repeat this for Milli Seconds, Seconds, Minutes & hours hands.
Hope this helps,
Krishna Chaitanya GT.

Solution #3 (Posted by Guest on 5 Mar 08) is spot on. Quick and easy method to reset the chrono hands (it was not in my Seiko manual).
Interestingly, this can also be used to set the chrono ahead (or behind--with a little math) for offset timing measurements.

you often need to do a full reset on 7T32s (& other seikos) after a battery change. there is a small reset contact in the rear of the movement which needs to be shorted to the top of the battery (the movement is engraved with wording to this effect, something like "AC reset", I can't remember exactly). you might also try pulling out the crown all the way (2 clicks) then holding both upper pushers in for a few seconds. it's unlikely to be a buggered motor unless it's one of the subdials that's failed.
