Two mornings in a row now the gmt has seemed to advance an extra half date on the date window leaving it caught between two numbers when I wake up at around 7am.

E.G. this morning as per the pic it should have been 10 but is in fact halfway between 10 and 11.

If I advance it manually thru two or three date changes it’s fine so this must be an overnight thing.

Any ideas anyone please?

I’ll try to do a time lapse on it tonight to see when it happens.

Yep. I have the same issue. Mine also jumps 2 days at a time also. It seems to rectify itself occasionally and then go back to its bad ways. There was another on WUS yesterday so assume it’s starting to become an issue.

My watch will be on it’s way into RSC when back from hols. No biggie, but sure they can sort it.

thanks for the info steve. yes mine was running fine for 1 month before this started happening. at least with date overshoots on a gmt, you can reverse the date instead of having to go fwd thru 30 days. i guess i'll check mine into RSC too. shame as its been on the wrist non-stop since i bought it!

Since then the date window has been running perfectly and the watch only gains less than 1 second a day !

Did you ever find out what the problem was?

They told me that the date wheel needed regulating.
But I noticed that the watch accuracy was greatly improved after the service
It used to be around 2.5 seconds a day forward. Now for the last 17 days, it has only gained 11 seconds.

peterpl · 10 July 2018, 06:34 PM

Damn thats disappointing.

This is why I am scared of buying any watches with new movements. Rolex/Tudor seem to have issues with date flips which is a very simple complication

The DD40 and now this Tudor GMT both have date change issues and both happened with new movements in their first models. Wonder whats up with their quality control and testing of these new movements. Its quite a simple thing not to get wrong.

Stevec14 · 10 July 2018, 07:03 PM

It’s frustrating, but not the end of the world. I wonder if more will come out the woodwork.

It’s just a PITA to have to change my date every day!

Possible a tiny bit of oil on back of date wheel just cycle the date around a few time should cure it.

watchwatcher · 10 July 2018, 11:50 PM

Second Peter's suggestion...please try that and let us know. I was thinking of picking that watch up later on in the year...

Stevec14 · 11 July 2018, 02:56 AM

I wouldn’t have any tools to open up. In any case, I would rather RSC dealt with for a new watch under warranty.

Is a shame. There are now 2 others on WUS with the same issue. To be fair, it is what it is and I’ll get mine in after I get back from holiday. Is not stopping me from enjoying the watch.

Hopefully not many more, and then I can sell mine as a true Mk1 with knackered date mechanism!

Oh boy... just when I thought I was safe...

Having seen my Pepsi change date flawlessly for the first ~32 days, I felt I'd dodged that bullet but the other day I noticed it had jumped a day... sigh.
I do appreciate that some of your watches have managed to get through the ordeal without a trip to the RSC and I will do the same - give the watch time to distribute the excessive lubrication. Hopefully. *Knocks on wood*

I recently sent another new watch in (to the official Service Center) and it came back scuffed up... and having OCD, I'm now much more reserved about sending in a new watch...

Regarding a theory that the issue existed only with the first "batch" or "a" batch; I took receipt of mine this past mid-November and it's one with the coveted rivet bracelet so there is really no chance that this sample was sitting at the AD since July... . I would have hoped that by now Tudor would have taken control of the issue!

Too bad, it's such an awesome watch!

Some stats:
date wheel "snaps" to new date roughly 7mins past midnight (my 126600 about 6mins after)
SN I764nnn
purch date 20th Nov (EU region)
Accuracy: +2~4/day

I'm wearing it for New Year's Eve... I guess my friends will be wondering why the heck I'm staring at my watch so intensely come 00:06...

Good news, my GMT did snap from 31 to 1 in a "timely" manner for NY's

So I've been monitoring mine every night and every night, the date has jumped (in one go) to the next day around 8~10mins past midnight.

Until this (Fri) evening. I had it on and glanced at it roughly 15mins past midnight and I was surprised to see it still showing Fri's date (11th). I glanced at it several times until ~01:15 and that's when it finally changed... to this:

It has clearly "shot past" the 12th and headed to the 13th. I presume that sometime tomorrow it will show the 13th and tomorrow night, I bet it will jump to 14 as if nothing ever happened.
I'll keep everyone posted.

peterpl · 12 January 2019, 12:09 PM

I thought the movement was an instantaneous date flip? Does the date change gradually or is it an instant click over to the next date?

Well looks like I was waaay off...

Taken at 00:43 on the 13th - no change from the night before

pulled the crown out to the 1st notch and as soon as I started turning the crown,
it sprung all the way to the 15th... go figure.

Instantaneous just like it's bigger brother, Rolex. Hence the title of this thread: "Tudor gmt date window ISSUE"...

Interesting. Maybe I missed it, but can you tell me if it is HOLDING that position between two dates, or is it eventually moving to the next date but sticking only for a short time?

I'm basically never up between midnight and 1am so I wonder if maybe mine is doing the same thing but I'm never seeing it?

Thanks

As I noted one post above yours...
"Taken at 00:43 on the 13th - no change from the night before"

josephvman · 20 January 2019, 12:35 AM

Send it to RSC. It’s not going to fix itself and the sooner you send it the sooner you’ll get it back. Been there, done that.

ROFL, that's always risky - dropping off a watch, not happy to go home watchless and seeing something tasty from the corner of your eye...

I, on the other hand, played it safe and walked into my AD wearing my "Tudor backup watch"...

Done deal. This could have been the one issue that could have fixed itself, assuming we are certain it's only a question of lubrication (and I'm not, at least not 100%...). Indeed, it appears to have worked for some. The only question is if it was really a permanent fix...

Anyway, a moot point for you and I ...and Tufty

nikhsub1 · 11 July 2018, 03:05 AM

Well, a bit off topic but I sent my Tudor GMT in for being way too fast. Was ~+7 seconds / day or so. Unacceptable to me.

Unacceptable would hardly call +7 seconds way to fast.

Some here will try to tell you that +7 is not way too fast. I certainly think it is....for a $4,000 watch. I can buy an Invicta that is 7 seconds fast. I like fine Swiss timepieces for their engineering and accuracy. If Rolexes started being +10 seconds per day, the would lose a lot of appeal.

tottallyoff · 11 July 2018, 06:16 AM

surely +7 is still within COSC certification. Right?

Nope. It needs a tweak.

Mine despite not being able to show the correct date is less than a second a day out.

Jocke · 11 July 2018, 06:21 AM

That is a common problem when you use the India timezone as the second timezone.
