I've had my Omega 3573.50 for a couple of weeks now and it seems to be running fast, about +7 to +10 a day. That's not so bad that I can't live with it, but I stopped by the AD and they told me it is +0 in one position and +13 in another, and points in between in other positions. I can't recall which position was the fastest or slowest.

My questions is:

Is that much position variation "normal" for that movement?

Or is it a symptom of some problem? Should the movement be more consistent or is that the way they are?

My Rolex's are about the same variance in any position. Guess I'm just not sure what expectation I should have for the Omega. I know it's not a quartz watch and I don't expect it to be but I don't know if I am getting the most consistent rate possible.

The AD has it for examination, but I wanted to ask the forum folks what they thought.....

I have an 1128, whose base is an ETA2893-2 and an 8500 and they are about the same in all positions, so I suspect yours needs a tweak. To be honest any chronometer based movement of any brand should be pretty consistent.

Perdu, thank you for the response. I deal with endshake, mainsprings, timing, and even "the hand" in my other hobby.

I'll see what the dealer can do for me....

The 3573.50 isn't a chronometer certified movement though...

I have the 3570.50 and it also experiences some variation. If I wear it or leave it face up, it is about -8s per day but if i put it on it's side, it is about +6. I just alternate positions and it is spot on for months. They should easily be able to tweak your movement but I don't mind it as long as it is consistent in the different position. Now if it were jumping around all over the place, I would have it looked it. Let me know what happens, I'd be curious to know if I could adjust my watch to w/in chronometer specs...

I will post a follow up. My concern is to make sure there is nothing wrong with the movement. If it that different in various positions, so be it, if that's the nature of the beast.

As above, the cal. 1861 is a non-chronometer rated movement, so greater positional variance is to be expected. However, +/- 7-10s per day is fine, I really wouldn't worry about it

That's pretty much what I figured but the AD is taking a look at it just to make sure all is well.
