Time accuracy, regulation and "reset"

[coralhound]

I have been wearing my new to me Submariner (2005) overhauled in March by a Rolex guy but not an official Rolex center. It seemed it was running fast. So Tuesday I set it to an atomic clock online. 56 hours later its 92 seconds fast.

During this time I have placed it crown up all nights (the slowest of regulation)

I called the dealer and they have asked me to let it wind all the way down to stop and then manual wind it 40 times to reset it. They said sometimes it will need to break in slightly after a full overhaul.

After this reset they said set it against the atomic clock. They believe it will clear it up. If not they will adjust it.

Is this a legit process?

Thanks in advance

I have heard/read of cases where the watch became more accurate a few months after service.

I would give it another 30 days and re-time the watch and if you are not happy, bring it in for a simple regulation

Great watch

I don't know about that practice but my SubC and DSSD keep better time now than they did new. That's a big difference for 56 hours. I don't think there is that much adjustability in the microstella screws to get it running perfect. I would think seething is wrong.

I have to ask if you have checked the accuracy correctly because 90 seconds fast in 56 hours is a lot of microstella or positional variation correction.
If your dealer seriously suggested it will slow down by 38 seconds/day when it runs in then you need to go elsewhere IMO.
On a Rolex you would be struggling to manage a positional correction of 1/10 of that. This is what make these watches so accurate - they don't vary much with position changes.

Sorry I wanted to be clear, they think that after it runs to stop and then I manual wind it it will clear, if not they have said they will readjust. I will have to ship it of course.

They said that if it gets to +7 a day after this then it will likley settle in a little more.

Legit?

Even after it settle down there is no way to correct so
many seconds

[Tridor]

I think it needs a serious regulation. That's way too much of a variation to be corrected as suggested.

Good call and worth a try on a holiday weekend. I will sync now with the AT and see if there is ~30 seconds in 24 hours. Then let it run down.

Thanks for the advice everyone.

I just synced it and may have some more insight to my issue. Within a minute I was a minute fast. I think it advanced immediately. If I did that before than 32 seconds over 56 hours isnt too bad?

The other thing I noticed was when the seconds hand crosses 12 the minute hand is already moving off the minute marker. Its synced now for 5 minutes, I will see what its like in 24 hours.

Sorry if this was a NooB mistake.

My Raymond Weil and Montblanc watches track very well!

A minute fast within a minute???

You may have a miniature time machine on your wrist!

In all seriousness though...are you sure you're actually reading the time correctly. Sometimes the minute hand is ever so slightly off when the second hand sweeps past 12. In that case, you should still be reading the minute hand as if it's where it "should" be.

I don't know. I'm a bit confused...

Yes that is what I think happened the first two times i tried to sync. I have compensated for it now. 12 hours elapsed (most of the time in a dormant crown up position) and its 5 seconds faster than the atomic clock.

Myself think you are over complicating any sort of a time check just wonder if you have a quartz watch.Now if you do wind your Rolex watch manually first 40 full crown turns clockwise.Then synchronise your Rolex with the quartz watch wear your watch as normal for say 8 hours plus a day.Check time daily with the quartz watch then average the lose or gain over the 5 days for a accurate enough test for your Rolex watch.

Not allways. With the micro stella screws in the balance it can de different. There are micro screws in the balance which can be screwed in or little more out.
My watch (15053 , 3035 mvnmt) runs a little faster while crown up (+5).
The watch needs no reset during months , it is spot on. Wear it during the day and crown up during the night. Atomic accuracy

Well when they regulate and make fine ajustments to the beat rate timing rate that is achieved by turning the Microstella adjustment screws and nuts.The two smaller Microstella screws make adjustments of one second for each turn, and the larger Microstella, two seconds for one turn, but rate adjustment on the balance wheel its around a max of 30 seconds either way.

How did it run before you sent it out?

I'm at -2s/24hr after 25yrs on a 16013 Datejust. Serviced once.
I think you should have another pro get out your watch. Like a medical "second opinion". Cost bucks, but you'll have peace of mind. At least I would. My 2005 Breitling has migrated from COSC spec to -13s/24h. Drives me batty. Thinking of sending it in for COA.

Post back after a bit...I hope it improves.

[coralhound]

19 hours since sync, 8 hours of which were "dormant" crown up while I slept. Its currently 10 seconds faster. I will check in again at 24 hours. My plan will be to let it run to a stop and wind 40 times and sync again.

Goose,

I just bought the watch a few weeks ago, it was overhauled just before shipment. They are standing behind the work, I thought this run to a stop deal was a little hokey but I will give it a shot. More than likely I will be sending it back for them to recalibrate.

As you can see I had some user issues the first couple of times syncing it.

[azguy]

Keep us posted

[coralhound]

24 hours = +14 seconds

Its been off the wrist for 3 hours starting the wind down.
