My GMT II stopped

[marzzz]

Mine is a 116710 BLNR I purchased new in 2015, and has been my daily (one and only) wearer ever since. Closest it comes to water is the shallow end of a swimming pool. From the get-go it would gain exactly 1 second/day, and I would reset it every Sunday night. I rarely, if ever, wound it, and it was never off my wrist for more than 6 hours. Over the past month or so it has on a couple of occasions completely stopped, but when I reset it to the correct time it would go back to keeping near perfect time. Until it stopped again, usually days/weeks later.

Yeah, I know, probably time to send it in for service. But I am curious as to what may be causing this issue? Oh, and when you send it in, in general how long has it been taking to get it back? Thank you all.

Rotor axle wear and rotor grinding bridges => dirt everywhere in the movement.

Yes this happens, but damage to this extent is not that common. For the bridges to get this damaged the axle needs to be worn out significantly, and you would easily hear/feel it bang and scrape around.

That’s too bad. Just send it in to the nearest RSC. Since it’s out of warranty, be prepared for a bill of $1,000.00, or so, and you should have it back within a month, or so. Good luck. In the meantime, buy a nice economical watch, to wear, while it’s gone.

I serviced my 2007 GMT and oils were dried up and I replaced the mainspring and escape wheel. It was still running reasonably well considering the movement’s condition. Yours will run like a champ again after an overhaul.

Eight years is a long time without service where the watch is worn everyday all day. In a rotation, watches may go further but not as one. Just send it in for service. Oils are probably dry.

[Ontime]

I suggest you take it for service.

[Alex71168]

I suggest a services. As you’ve worn it continuously for that long and rarely even taking it off I guess the rotor has worn.

It’s mechanical, can fail anytime.
I have some running over two decades without issues

Could need a service or simply you are not active enough when wearing to keep mainspring at peak power.And a stopped watch should be always fully manually wound before wearing at least 40 full crown turns clockwise only.

I agree, a service might be needed. Usually 4-6 weeks turn around time on average.

I agree with these guys.

I’d give it a full wind and set it aside to see how long it runs.

[996marty]

A good overhaul will sort it out then I’m sure it’ll be fine

[1William]

A full wind and wear and see how it does.

[marzzz]

The funny thing about the full wind, my original AD retired and closed his store a few months back, and I went to another local AD to introduce myself. Mentioned that my BLNR was 8 years old, never wound it, never had any issues. She suggested I wind it every week, and that's when I started to see the stoppage issue (!?). So off to the RSC it will go this week, thanks to everyone for your responses!

If you are winding it fully, weekly, even though you did say that you "rarely, if ever" wound it, then we might have had a different suggestion.

A watch wound weekly, consistently, that still stops may very well have an issue with the auto wind. The reverser wheels swing into a different position when the rotor changes direction. Lack of lube or some damage can cause this module to malfunction, one of Rolex "weak" points.

In the old days a watchmaker might take the autowind off if it malfunctions, turning the watch into a wind-only time piece.

Funny how all the replies have been helpful, but if this were a 32xx from the same era, we would be six pages deep on how the 31xx is far superior.

If it was a 32xx, there would be amazement that it had lasted so long without a service!

So a quick update, took my BLNR to the AD today (8/14), and a different "Rolex expert" recommended I try winding the watch on a regular basis, and if it stops again then take it in for repair. OK, I am willing to give that a try, but he did say that for repair they had someone who was certified on the premises who would do the servicing, as opposed to sending it to an RSC (Dallas?). Anyone care to comment on this? Is it okay to have it serviced locally? Thx

Get it serviced by RSC.
