How accurate is your Omega?

My PO is very consistent.
Place it face up and it slows over night.
Place it at 9 side and it speeds up over night.
I alternate these positions and am currently regulating at +0.09/day.

I wish I had a loss speed position but all are positive. After a typical day of wrist time and overnight crown down (slowest gain), I range from +2.0 to +3.5 spd with an average of +2.8 spd. I know it's within tolerance but it was bothering me when I first got it... now I've learned to embrace it's quirk and don't want to risk unnecessary case back opening (even if it's via an OB).

Better to be able to manage a watch that's running a bit fast than slow.
It's an essential part of mechanical watch ownership.

My 2018 Speedmaster professional gains 8-10 sec per day, sometimes more, rarely less. I'm not happy about that, should that be corrected?

If those figures are on a timeographer then it's within specs so Omega won't touch it.
Perhaps you need to find a really good watchmaker and get them to play with it a bit to bring it within your acceptance range.
If that's on the wrist, then there's plenty of space to play in.

If you're near an Omega Boutique, the tech will likely adjust it for you. The tech at my local OB has done that twice for me with watches back from service, which greatly improved the accuracy.

I'm curious - why do people prefer a running fast vs. running slow? Is it because you can simply hack and hold to catch up if fast, but slow requires a marginally more complex reset?

Always better to arrive early than late to meetings/appointments 馃槈.

My FOIS is +12-15 seconds per day. It's been that way since I got it, (new) and while a bit fast, I've got no problem.

Been using the WatchTracker app recently after about 8 months of ownership (SMP 8800). Before, I would gain about +2s/day when I laid it dial facing up before bed. Recently, I've been resting it with the crown up (9 o'clock facing down) and have been -0.1s/day which is better than I could've asked for. Not sure exactly why, but have nothing to complain about.

I have 2 Seamaster 300 divers with 8800 movements, both are exactly what I want for accuracy. Both are to the + and both are less than one second + in 24 hours. I have also had the same experience with the 8900 movement in a few Planet Oceans. Over the years I have had several Rolex examples and none have been this consistant in accuracy, newer green tagged models as well. As far as accuracy with Rolex it's a roll of the dice, some to the - and some to the +.Yes for me accuracy is important when spending this much on a watch. Due to unavailability and pricing at Rolex, for now call me an Omega guy.

Thanks for your reply!

I'm wearing it every day and I'm also measuring it every day and now I have a 2 year record 馃榾

I also demagnetized at one point when it went south, and that put it back to the +8-10 range.

I will take your advice and go to an Omega dealer. Under say +3 is a wet dream....

My vintage Seamaster that was my dad鈥檚 and is circa 1952 loses about 2 seconds a day. My brand new Speedy runs about 3 seconds a day fast.
So I guess they average +1 second a day!

All four that I own are within spec and not running in the negatives. I am very happy. My Blue AT 220.10.41.21.03.001 is about +.4 seconds a day according to my app. My timegrapher doesn't measure in decimal so it calls it 0 s/d.

My current model AT with 8900 movement loses <1 second per day, which is slightly annoying but still very close. Its certification was +3.2 sec. I also have an 8806 movement SMP 300M ceramic that is right at the +3.5 spd that its certification indicated.

Interesting - I know there isn't always alignment with the METAS certification but mine was fairly close IIRC. Regardless, I thought the accepted tolerance is average of 0 to +5spd. So -1spd is probably outside tolerance (assuming this is the average as opposed to a bias towards one position of another such as dial-up).

My 8800 300m us running about +.75s/pd. Usually after about 10 days when I'm 7seconds fast will I hack the watch for a few seconds and square it back off.

Pretty damn impressive how accurate they have scienced these things.

Resurrected this thread for others looking at accuracy.

Wore my 8800 diver for 4 weeks 24/7 so a real world accuracy?
Over the 28 days it gained 2 minutes 12 seconds or 4.7 seconds a day, hope this is of use to someone! Off to wash my wrist now.

My 2018 Speedmaster 1861 runs about +7 /day seems to get magnatized a lot, no matter, it's getting traded on a 3861 Sapphire very soon. My daily driver, a 38mm Speedmaster 3330, is consistently +3/day, certainly within COSC standards. The 3861 should be easier to track now it hacks.
