My AT with 8900 gains about 0.5s a day when constantly wearing it. Placed on the counter face up, it gains more.

My new to me Seamaster PO 2201.50 is running between 0 to +1. Good signs.

My 3861 Speedy is around +3.5-4 per day.

Don't know if you saw it but my 2254.50 has had a bad experience with magnetism and my M1 MacBook Pro. Something to watch out for.

I will. I've worn mine while using my Lenovo laptop. I'll have to do some observation.

My 1861, after 5 years or so of running at +5 is now running at -3. OB told me that it had been magnetised at some stage recently (though that should make it run faster and their demagnetiser made little difference), but I figure it’s due a service soon and it’s still running accurately enough for a compilation of cogs, levers and springs 😉

I found that my 3861 varies depending on how it rests at night. When it stays crown up, I’m getting +0.5-1 sec/day. When it sits face up, I’m getting +4-5 sec/day. Nothing scientific, just comparing it to time.is every morning before I wind the watch.

That's all to be expected and within norms.
It's a good result really and something one can easily work with day to day👍

My SMPc averages at -1.1 s per day.

My PO averages at +1.2 s per day but I need to put crown up at night.

I've had my Seamaster 300M for 18 months now and have been astounded at its accuracy from a mechanical movement, about .3 sec a week gain (job to tell!) sort of thing I would have expected from a quartz movement!

I have this watch also…. Mine is a 2017 ,Just Regulated and very accurate thus far. No deviation to speak of, yet.

My Seamaster 300 Trilogy is my most accurate watch, at a consistent -1 sec per day. Rock steady.

My PO MK1 was dead on every day if left in position, for years, but after an Omega service, it's dire and is the first time any of my PO have run fast as opposed to losing 1 or 2 seconds a day, but after waiting for almost half a year to get it back, I can't be bothered to let them have it back

I bought a 300SMP in August. It averages +3-4 sec/day. Would have preferred a little tighter but within tolerance.

My new green SMP300MC (cal. 8800) is about +2 spd on the wrist and -2 spd stored dial up.

My Archer serviced chronographs run synchronized to the atomic clock. A 145.022-69, 3894.50, and 2298.80. Worn or dial up.

Haven't really paid that much attention to my 2254.50 and 166.0324.

So many amazingly accurate Omegas.

5 yrs old, Just inspected and regulated by Omega trained Watchmaker ,48 hrs ago. Exact same as Atomic time Sync’d.

I’m sure that will change… yet I’m enjoying it as of now

I have an Omega Seamaster 300 Heritage and since setting it on November 6th (15 days ago) it has gained approximately 12 seconds. Which means it is less than +1 second per day. Stored overnight crown up. It was purchased March of this year and based on anecdotal evidence it is consistently running at less than +1 per day.

Ironically, the Watch Accuracy Meter app says it runs at -1 per day averaged over 6 positions. So the watch is more accurate than the app.

Gotta love that.

I have two Metas watches. The Globemaster runs consistently -0.3sec/day and my Constellation (8800 movement) runs at +2sec/day. I have several non-Metas Connies. Two with the first gen. co-axial. One is running at +4sec/day and the other is dead nuts at 0sec! Pretty impressive by my standards! I don't know the service history though as I bought them used.

All Watches in this thread are lousy performers. Send them all to me in exchange for a nice Quartz Watch. I will even pay the Postage.

I don't measure my Speedmaster Pro day to day. I check it roughly once every 2 weeks or so, and it's been consistently averaging around +3.5 seconds a day for months.
