A7750 GMT Reliability

[nakortheblue]

Anyone with experience?

Is the A7750 GMT as reliable as the ETA2824-GMT-ICHS?

Or will it be as problematic as the ETA2824-GMT-CHS?

I'm thinking of getting a GMT PAM.

Thanks for looking.

The A7750 GMT is no where near the poor quality or workmanship or crap that the ETA2824/36 modified GMT models are known to be.

My experience with them has been mostly positive and reliable. The only issue I have seen is with the quickset for the GMT hand, on the Asian models they use the datechange gear for the GMT quickset, this requires the gear to swing all around towards the center of the watch to get engaged into the GMT gear and move the hand. I have seen issues that are not repairable where datechange gear won't engage into the GMT gear...or does so intermittently.

Other than the GMT quickset, the basic design and reliability following servicing has been 100%.

Thanks for the great info, watchdog.

Just wondering, do they fall into the category of modified movements that you will not service?
