Brand new watch losing 5 second

[AndTylerToo]

I purchased a brand new 36mm oyster perpetual at an AD yesterday around 11 AM. Today, 27 hours later the watch is already running 5 seconds slow. I know this is outside the standard range. Any advice and/or thoughts? Thanks in advance!

Let the watch settle in a bit first before making any rash decisions. Give it a few weeks and keep an eye on it.

I will do that thanks. Just out of curiosity, is there a kind of “breaking in period”?

I wouldn't call it a break-in period so much as a settling-in period. Precision mechanical devices often need time to do this. Especially ones with tight tolerances like wristwatches. Often, when a watch comes back from service, it takes a week or so to settle in again. Lubricant needs to work it's way into the proper places, etc.

Correct.

Understood. Thanks very much!

Several of my watches were out of spec initially. Not Rolex but Tudor and omega.

Tudor was 6 sec a day fast, within a week it became my most accurate watch. It was exact for a while before going between +1 and +3

Omega moonwatch was +8 to +10, worrying actually... now +3 consistently.

I rarely check these days, only when new then once a year.

gotta love this forum!

And if it does stay at -5, you're covered by the warranty. You'll need to decide if it's worth sending the watch in for a relatively minor deviation, but the option is there if it really bugs you.

[AndTylerToo]

And, if I’m wearing it every day no need to wind it too right? Sorry for the basic questions. I’m new at this!

[bp1000]

Yes it’s a self-winding movement

Providing you keep moving it will keep going - otherwise it will last approximately 2 days at rest.

Ps
If it stops after a period of rest, give it a full wind, 35 - 45 full turns of the crown. Good to go thereafter.

If I haven't wore one of my automatic watches that I keep in a winder for a while and their timing is off a bit, I simply reset the time/seconds and forget about it. Enjoy the watch.

No. For rolexes post 2000 the quality control stepped up significantly , for the new watches no break in period. Serviced ones yes, long periods or short break in depending on the service place, engineer etc.

I would observe it for a week and wear it as much as you can. give it a few winds every morning.

In a week if you still have the issue, speak to your AD. Request an exchange or pop in to your RSC if possible, they will check it if it's a problem of regulation and can be fixed on the spot within 20 minutes. If not they will advise on the next steps.

I wouldn’t worry just yet as the others have stated. Personally i would give it two weeks and see where it lands.

Did you try resting it dial up at night? This seems to be the fast position for many. If it is for yours, it may help compensate for the time it loses on the wrist.

This may sound silly - but did you fully wind the watch upon purchase?

My first modern automatic watch was a Sinn 556. When new, it was +2s. After about a week, it was, and still is +0.7. My newish Rolex 114060 was about +1 for the first week and has been about +0.5 sec/day for the last month.
As others have said, just give it a couple of weeks or so.
By the way, I was pleasantly surprised that the top grade ETA movement in the Sinn is nearly as accurate as my Rolex.

I find a new Rolex takes a good few months to settle down. I’ve had a number that are 3/4/5 seconds per day out at the beginning, and down to 1 or 2 seconds six months later.

Make sure your time reference is absolutely unassailable.

Time.is is one such reference.

Don't trust your computer or a so-called "atomic" clock, as both only update periodically and both can drift considerably between updates.

I agree with those who suggest a "settling-in" period.

I have no explanation as to how that works, as not everyone agrees that there is such a thing, but my experience is that your new watch will keep time differently after a few weeks.

Even if the time is unacceptable after that period of time, you can have the watch regulated under warranty.

Ive just serviced my titanium breitling avenger bandit 2 months ago with 7750 and fine tuned it . Its running 0.1s/d measured weekly last 8 weeks (minus 1st week) . Far better than my newish Daytona which has been regulated by RSC

[Byrdguy]

Kind of like the squeaky bracelet syndrome. Wear it and let it settle in.

[Spam16v]

My new 216570 is running a few fast but I’m a 20k step a day guy around my plant so I presume if I were reading the Wall Street Journal it might be just right. ;)

Glad you mentioned that. The rep at the AD wound it but not sure how many times. Would you recommend that I rewind? If so, how many times? I understand it has a mechanism to stop winding too much.

I have been wearing it pretty much non-stop except for sleep since yesterday.

Give your watch forty winds.

It won't hurt it, as you cannot over-wind a Rolex, and it might actually help, if the AD didn't do the job correctly, which would not surprise me.

Will try that and rest it face up tonight. Thanks!
