Icon11 How to slow down a GMT Master II?

My GMT Master 2 runs 9 seconds fast a day. What is the best position to leave it at during the night to slow it down and lose some seconds? Thanks

Rolex used to supply this with its watches. I have heard that it is obsolete now, but it seems to work with my Tudor Black Bay and my 1991 Datejust, so it might be worth trying.

If it is gaining time, it MAY be magnetized (5 min job at any AD).

If that does not work, then it would need to be tuned. It would help to know how old your watch is and if it went through any jolts, etc... Also has it even been serviced?

I agree with the above about the possibility of being magnetized. Was it around strong magnets any time recent?

If so should be an easy fix as mentioned above. It's the only thing I can think of at +9 secs a day. I'm not sure changing the crown position when off your wrist can make up that much of a difference in this case.

Interesting, mine is consistently 11sec fast. I wonder if it somehow got magnetized when it was going through customs?

A magnetized watch usually gains alot more than + 9 seconds a day. You would be 30+ seconds a day fast if it was magnetized.

Leave it overnight with the crown facing downwards. It should lose a lot of seconds. If a ceramic GMT it should really only gain one or two seconds a day max. Get it regulated if you continue to see that large of a deviation.

It may not be an overnight job cause tuning required opening the watch, and once that happens it goes through an iteration of tests to check for waterproofness. And if the watch is under warranty, your AD (unless certified for such) will need to send it in to RSC, then your talking weeks!

The newer movements aren't affected as much by position overnight from what I understand.

It doesn't need to be "serviced", as in an overhaul. It only needs to be regulated and that could be done while you wait.

The newer Rolex will in fact react to position. I have a GMT II BLNR (2013) and when it leave it crown up at night it will consistently loose about 2 sec/night. During the day it will gain 2-4 seconds. And its nearly the same with my Tudor Heritage Black Bay (2016) and GMT II (2005). They all loose time with crown up over a period of time and will gain about the same when dial up.

I'd get it regulated when its convenient for you. Should be a very quick fix.

Magnetized watches are typically in the + minutes range, so I doubt thats the case here.

If it's still under warranty the only one who can regulate it is Rolex Service Center, if anyone else besides them open the watch the warranty is void. (at least that's what RSC told me when I called multiple times to confirm this.) Someone correct me if I'm wrong, because I would love to be

If your watch is a consistent 11 seconds fast then can assure you it's not magnetised just needs regulation.

The less a watch is opened, the better. Not worth the effort or trouble for 9 seconds.

Ok thanks! I'll probably just leave it be until I have it serviced then.

It's most likely not magnetized. It would run erratically and a lot faster.
I had a watch get magnetized once and it went from +5 spd to +20 spd right away.

I would suggest talking to it and explaining that life is two short to be running that fast. If that doesn't work well ... I am afraid you may have to seek professional help.

I can vouch for this. It will lose seconds with crown up or crown down. My GMT is currently gaining between +1-2/day. Over three days it's usually a total of +4-5, so i guess about +1.6 average.
