GMT II C Accuracy after 2nd 30 day period

[blackeagle]

As timed against Time.gov Sept. 9, 9:15 PM - Oct 9, 9:15 PM

In this 30 day period the movement lost 24 seconds. So of the 20,736,000 ticks it was slow 192, or .9999907 accurate. I'm terrible with math but that looks pretty good to me.

That is fantastic!!

[Robb]

Awesome!!!

It doesn't get much better.

Congrats.

I know that I have to reset mine every couple of weeks just because I'm anal about time, but I have not kept track. It's usually around 1.5 minutes when I adjust. I must say, it kinda sucks only due to the fact that it is difficult because my crown doesn't "eject" easily, and when it does, there are NO definate "clicks" to let me know where I am in the movement.

Anyway, I digress...

I have similar results with my GMT II C. I have not measured it over 30 days. But, I just checked it after a week and it only lost couple of seconds. I am truely amazed at the accuracy and I don't even wear it during the weekends as much.

Still +0 secs per day here - no adjustments.

Have the Green Arrow owners noticed that most of us are running slightly slow to 0. I can't recall a poster saying their Robin Hood ran fast.

Mine is still running -4 seconds per 24 hours

Wouldn't worry C-rad - mine took a month to settle in.

Thanks AJ ... I feel better already

By the way C-rad, when you take it off for the night, how do you store it? Face up? Crown up?

I wear it while sleeping. I've thought about taking it off and laying it flat face-up for a night to see if that helps.
I might try it tonite.

Exactly what I was going to suggest. But again, as it's brand spanking new, all the gears are still settling in.

Exactly!

Also, try out the "Positional Correction" positions. They MIGHT have a small influence on the precision, might not, since the below overview more applied to the non-"fastbeat" mvts.

Anyway, here it:



So if your GMT IIc is losing time, try laying it DIAL UP (remember to put something between the caseback and bracelet so that the bracelet does not scratch the caseback.

Mine arrived about 1.5 seconds/day slow and after 30 days, hovers around 1 second/day slow. If anything, I would rather have it 1-1.5 seconds fast each day, but I dont think you can manually regulate anything closer that this.....

Ronnie,
I'm a die-hard Tiger fan ...... but at this point I want a +- 1 sec / day Robin Hood !!!



well and a National Championship

[bayhillrolex]

Well after 6 days it looks like my watch is starting to settle down.
For the last 24 hours it has been spot on

So for the first week of full time wear -24 secs or average of 3.4 secs/day.

Things are looking up

PS. I haven't been trying to regulate it at night by the positioning techniques, this is happening as I'm wearing it 24/7 except for very brief periods.

[redcalx]

I've had my GMT II for a few months now and I've noticed that it hardly loses any time at all. I reset it always at the start of each month and for October so far (today is the 12th) my watch is 1 second slow. I'm certainly not an expert, but based on what the rest of you are saying... that's amazing, no?

[blackeagle]

I think it is what we should expect from a 6k watch. It is nice to see progress in the accuracy relm. My 1985 GMT II lost 2 minutes a month for most of its 22 years of wear. It did get better after the last service.

I am an old guy, I expect my watch to be accurate. I grew up in the rural south and I remember the days at the Farm Bureau when the old guys were comparing their "Railroad" pocket watches and the accuracy they talked about. I have worn 3 watches in my 65 years. My first watch was a 21 jewel Waltham I got when I graduated from high school. I wore it from 1961 to 1985 when I got my GMT. That watch was never sent to a jeweler for cleaning or oiling and it never lost or gained. When my Rolex is being serviced I still wear it after all of these years.
If they could make an accurate watch then, they should be able to keep up now.

[vdave]

Yeah. I agree I am impressed with accuracy of the new GMT II. Looks like Rolex's investment in the blue parachrom hairspring is paying off.

But, I agree with blackeagle ...the accuracy & quality should go up with price.

Well appears after two days this week its back to running -4 secs /day

I had task someone a while ago, my GMT IIc only a few weeks old, loses 2 seconds every 12 hours, where as my GMT II lost less than 2" every 24 hours, my non SCOC no date sub, was in that ball park, loosing 2-3 seconds every 24 hours, my new GMT IIc is the worst at time keeping.....so much for the parachrom spring guys!!!

[frostie]

Not suprised at all it's a rolex
