How much time variance is normal on a new sub?

[Varus27]

Hello all,

When I first got my watch, it was gaining about 0.38-.5 seconds a day. I recently got it back from warranty work from RSC, and how it seems t be gaining 2.4 seconds a day. Is this normal? I know it's still under COSC standards, but I see some people getting INSANELY accurate time. This isn't a huge deal, but wanted to see if it's something I need to get them to check into.
Not sure if it needs to be regulated or just keep in keeping on. Thanks!

Cannot understand how anyone can measure 0.38-5seconds a day please remember are 86400 seconds in a day.Depending on how much power reserve the mainspring has and wearing habits time could vary slightly daily but your watch in fine a don't need regulation. And IMHO some posts on forum that boasts INSANELY accurate time either they must have a watch in 10000000 or live on fantasy island.

If you could have a watchmaker put it on a time grapher, you will know what the slowest position is, and then rest your watch over night on that position. You’ll probably get better than 2.5 spd. If that position is already the way you set it down at night, then 2.5 spd will be all you can do.

Gaining .5 seconds a day is amazing for a mechanical watch.

[S’portEye]

You are doing great with this watch. Don’t worry.

[Varus27]

Appreciate all the kind feedback, sounds like nothing to worry about!

Yes this is the speed after a night's rest.

This is what I’m talking about if one keeps opening up a watch for relatively minuscule imperfections. I know you are still contemplating on getting the dial replaced given your previous threads.

You’ll eventually find yourself in the rabbit hole at this rate. It will start taking away your enjoyment of the watch.

You are right, watch is great and I am past the dial issue at this point, been just enjoying it. I think I will avoid the rabbit hole and just enjoying the watch. I will get a dial swap when I service it and it will also take care of the time variance in a few years. Cheers!

Dial up, crown up, crown down all have different rates. Resting it on the slowest of these might get you better that 2.5

My sub runs 0.5 spd resting dial up at night and -1.2 spd resting crown up at night. If you are keeping track, do it over a longer period of time to get a good average; at least a week and take the reading at the same time of day.

If you just got it serviced, it will change over the next few months. I would definitely not have it opened up and adjusted if you are currently getting 2.5 spd. That is an awesome adjustment they did at service.

That’s what I’m talking about, wear it and enjoy the journey. Cheers

Yes, that's what I'd do. Don't know if the traditional guidance still applies today but it's what I use:

that does not apply. I have three 32xx movements, and each is different.

Rolex seeks to ensure +/-2 seconds a day.

[GradyPhilpott]

Give the watch 40 turns and wear it for two week or more and see where you are by that time.

I've had new Rolex watches settle in after a time.

Others claim that this cannot happen, but it happened to me and it's worth a shot.

My watches keep better time when they're not fully wound. YMMV. I'd suggest maybe 10 winds from a dead stop - then wear.

[Chewbacca]

Time is slower underwater like all movements so it depends.

[CarlOver]

0.38 to 0.5 spd? And watch was sent to RSC to correct this? Well, they are trying to teach you a lesson. It seems.

[S7gpt]

my sub, worn night and day looses 2 seconds a day - happy with that

I have 2 32xx movements and both respond to the regulation guidelines. Perhaps not down to the same exact amount of loss or gain between them, but the loss or gain is apparent, respectively.

[straho824]

+/-2 seconds a day its normal.

Same. Because of this all my watches "sleep" on their side at night with crown pointing up. I swear it makes a difference.

The bare uncased movements are still tested at the Swiss COSC to a average of between -4+6 over any 24 hour period to get the Swiss chronometer certification. Now on the actual COSC test in the first 10 days of testing the movement could deviate by up to 10 seconds either way in a single 24 hour period, and still pass the test.Now Rolex re-tests on a machine with movement in its case to this new -2+2 average daily spec just to say movement met said spec at time of testing.No purely mechanical movement will keep 100% perfect time no matter the price or brand, out of 86400 seconds in a day close yes, but perfect no just to many variables.

[George58]

just wear the dang watch and enjoy it

Obviously some have comprehension issues.

Read the thread?

To the OP.
Which model Sub do you have?

That is coincidence, and not by design.

The old printed self regulation guidelines do not apply any longer

Very well said Peter. Can we just enjoy our watches and not be so concerned if it’s not as accurate as The Atomic Clock.

Can members like you not just stay away from such threads where you have NOTHING to add?

Exactly this.
