Good Evening Gents,

 

I started this hobby a few years ago when I purchesed a GMT Master 2 from a site i was given by a friend that was into reps (they're not a TD here, nor would I recommend them)  The watch started to run fast on me, gaining a min a day or so.  Towards the end of its life, I could no longer adjust the 24hr hand, the watch was gaining 15+min a day, and finally the crown broke off of the stem. 

 

Does anyone think it would be worth servicing?  The watch does have some sentimental value as it was my first rep.  Any recommendations of someone in the CONUS to fix this?

 

Cheers!

Sounds like a typical 2836-ModGMT issue and possibly magnetized causing it to run fast.

 

It probably needs demagnetized and the GMT module repaired.  Or if you are handy, R&R the movement with a new one.

Im pretty sure I could tackle the R&R myself after doing a bit of reading.  I'd have to get the proper movement (was sold as an asian 21j movement.)  Would the movement come with a new stem and crown?

 

Other than the most obvious answer of a magnet, how would a movement become magnetized?

The Asian 21J "GMT" is really a DG3804b.  You can find them Ofrei or eBay.

 

My wife magnetized her gen Breitling switching off the Subwoofer to our Home Theater System once.  Also, some safe's have electromagnetic solenoid style lock mechanisms.

None on ebay, and OOS on Ofrei.  Time to start google'n.

 

Thank you very much for the info.  Im guessing my watch became magnetized from sitting near my computer speakers.

I believe the "Alpha" brand or "Chronotac GMT" Chinese GMT homage watches all use the same 3804 style movement.  Might want to search eBay for GMT watches under $100 w/automatic movements.
