This is my Seadweller (about 30 years old) and it's labelled Superlative Chronometer. Still gains a few minutes a month and was recently serviced at Rolex Canada.

Patek models from about 10 years ago were generally about +/-4 seconds a day. The new Rolex models are -1 for the 2018 Hulk, -0.25 for the 2017 SS SkyD blue, and think the 2016 Sub is like +1 seconds a day. Crazy accurate, though note when i wear a model it is worn 24/7. Seems to me they keep better time when left on the wrist all the time. At least it is in my experience. Hope this data helps.

I think it's a balancing act. I think they adjust the movement so that it accounts for a person wearing the watch a certain number of hours per day. If worn more or less or with frequent jolts, the timing can be off. I also manually wind mine depending on how much/little wrist time they get. I generally wear my sub-c 15 hours a day and lay it flat in a watch case for the remaining 9 and it works great for me with my current piece.

you need to remember that its also an average when fully wound across multiple positions (Face up/down, crown up/down, etc.) so depending on how you wear it, how often you wind it, how often you move to let the automatic works wind it, how you store it, your timekeeping will vary.

you could be 0 s/d in one position, and +5 or -5 s/d in another. If your watch isnt COSC certified, you can be even further out across positions.

You understand that's simply a matter of regulating the watch, not some intrinsic flaw with any of the movements in the watches you mentioned, yes?

I'm willing to bet your experience with IWC and AP are not the norm compared to most when it comes to accuracy.



Just because a watch isn't COSC certified doesn't mean it isn't capable of being that accurate (or even more accurate), it simply means it wasn't tested by COSC. Most of the top tier watch marques don't bother with COSC certification, actually.

This is correct, and if I'm not mistaken, only "Swiss Made" movements can even be submitted for COSC certification.

My Seiko 007 runs about 15-20 sec off per day, so not bad compared to these.

And is it just me or are some computers pretty far off of any accurate time standard? Not unusual for me to notice somebody's handheld or workplace computer time is off by a minute or more from my watch, but later when I check I'm still fairly accurate (certainly not off that far).

update: NO, checked my records and actually only lost about 6sec/day, DK what I was thinking

So far my Seiko Sarb033 has kept good time. My Submariner and Datejust run about 3 minutes fast on average.

That's not very good for same movement as my sport 5. Is it the Japanese model? I have skx007 also.

I’ve read people can regulate the skx to about +/- a few seconds. You can regulate the watch by how you place it over night and such.


The movement is good, just not pretty

You got me wondering so I dug out my notes, and you are right - it did not lose this much. Actually only lost about 6sec/day, so a fail for my memory rather than the watch. It is a Japanese model.

My Panerai is pretty good and i daily that. Tag Carrera is kinda crap tbh; nice looking watch but that movement is so bleh. Maybe it's my usage; but the movement is really tightening up and losing its time. Gets off by w couple minutes after a few days.

Moving your arm alltogheter will mess up the timekeeping.
Not only the position your arm is in.

A lot of people here seem to think that COSC is an accuracy for timekeeping.
That is only true if you dont move the watch. How the watch behaves under movement (something you cant prevent when you wear it) is a whole other matter.
If you regulate a watch with a timegrapher you can see that it can sometimes take 30 sec. or so before the watch is in a resting state that the timekeeping is constant again.
So how you use the watch also determines how accurate it is. If your useprofile is accurate you can regulate a watch to your specific behaviour.

For a strange reason I can't edit my earlier post in this thread . What I would like to add is that Zenith's El Primero movement is also as accurate as Rolex's movements that meet new Rolex standards

true, but generally, well put together newer watches dont take as long to get to the resting state, and cosc gives you a good starting point.

i can shake up a rolex 3135 and put directly onto my timegrapher and its at 0-1s/d right off the bat.

now some of the older movements, cant do that cause there is enough play in the jewels/gears that it takes a bit for them to balance out.

this 806 is getting near 60 years old. while I haven't made any effort to check it for +/- sec/day it's never been more than one minute off in all the time I've owned it.

My Rolex keeps +/- 2 seconds, which i think is pretty good for a 15 yeard old watch.. of course it's not keeping any time at all right now since it's in the shop for repair.

I never kept track, but only time I would notice watch was off is if I didn't last it flat overnight. I'd have to adjust time every other month due to not being quick set.
That was on my 1967 Datejust, which took a hit on the crown and is now only accurate 2 times a month...

Lots of good posts, thank you. I can only wear wood battery watches bc I kill the battery in metal watches within two weeks to a month for some reason. My wife started the wood ones after talking to a local jeweler. I have a few high end metal watches that are just about useless, but the mechanicals I’ve never considered. Will need to dig into this.
