How accurate is your watch?

[Steel28]

After 44 days since purchased brand new my SubC runs at -1 sec a day.

[Kyle3130]

My 14060M 2 liner is running+.04 seconds per day since the time change 23 days ago!

[Racerdj]

My Daytona's are running +2 and +3 per day while the Subs are +1 per day.

[Laszlo]

Both within spec.

My DJ 116234 is more accurate than my Sub 114060. Only by a hair though. Amazing timepieces.

[samsam]

I do appreciate the mechanics and what have you behind this, but I personally don't care as long as it's not awfully off.
I honestly get my watches cuz I enjoy looking at it. Otherwise, I would've gotten this atomic watch synced ones.

HAGD everyone!

+ 1 sec. per day

[brandrea]

I've never paid attention to it really.

I only ever adjust the time when I have to adjust the date function, or if I'm using the second time zone.

[Widows Son]

I've never checked, or felt the need to. It's more accurate than it needs to be.

Last time I checked my 5513 was April 1st 1989 just checked it now and its .9999987 of a second fast beat that one.

[rockinray]

My 16803 Sub picks up about 4 seconds per day.

[tonypapa67]

SubC +0.8 seconds per day.

[polarinda]

+14, +18, but i could care less. I adjust it mid month -5mins. Good enough for me.

[JMAK]

My F series Sea Dweller is +2 sec/day, and when I put it crown down at night it loses 1 sec/night.

[rkim11]

Just set my M LV 13 days ago and its running at +3.38 secs a day.

That's an April fools joke right....?

[rw170driver]

My 116710 loses 3.2 seconds per day on average. I lay it face up at night. I'm still amazed at the engineering. 3 seconds out of 80,000+ per day for a mechanical device is simply mind blowing to me. I set it a minute ahead every month on the first. This month I might try winding it just to see if that impacts anything. It hasn't been wound since March when I bought it.

Daytona 116520 D Serial .4 seconds

My 1985 Sub is +3/day. Last serviced April 2013.

My BLNR is +.25/day.

[fmc000]

1991 Daytona - about +1.5sec / day. Not bad but if you're an accuracy freak I suggest a Breitling superquartz. Mine was about +2.4 sec/year.

My Sub is wonderful at + 0.23 per day.

[postalworker]

-2 seconds every 24 hours

[yahoo_mks]

DJII random serial - approx +2 sec per day

[RLROCK]

The first week with my new GMT II c and I am running a total of +8 seconds for the 7 days.
Now if I can only get the band to stop squeaking.

[OmegaJJH]

+ 10.8 seconds per day on my SubC.

Trip to the a Rolex SC for me.

I've just started a thread titled Rolex Service Centre UK question where I'm looking for some advice if you all wouldn't mind taking a look.

[RolexPete]

Mine is a shade under 2 seconds a day fast. I can live with that. If I tried I could get it closer to zero by resting it in a certain position at night.

I'll admit that I'm a bit OCD when it comes to timing. My 43YO GMT 1675 runs about -4 sec./day after recent service and my new-to-me Daytona 116520 is +5/day, also after recent service at RSC. I find both to be outside my comfort zone but not unnervingly so, as I would like to see no more than a minute variation per month (2 sec./day).

Has anyone attempted DIY regulation? I understand the principle of the four small screws on the balance wheel, where turning in speeds and turning out slows the timing, but this requires special tools. Removing the case back is not a big deal, but can one buy the regulating wrench needed? All that said, even though I maintain my own cars, motorcycles, etc., I don't think I would attempt doing anything beyond looking at the watch movement.

I watched a watchmaker do the regulation on my GMT once and in one hand he held the balance wheel with tweezers and did the regulation with the other. It would seem that holding with tweezers might stress the delicate mechanism.

[elcompa]

New BLNR is about + 0.4 sec. per day.

[Ed Man]

My sub has been running at about +1 sec since I got it 12/30/13.

It's not difficult at all. You just need case back tool, tweezers, a microstella tool, and a timegrapher. All of which can be readily purchased. As for stressing the mechanism, it's not that delicate (hairsprings are) and you won't hurt it by holding it immobile with tweezers. I've also used a pegwood stick to do the job - it just depends on how you're trained.
