This past weekend I purchased my very first Omega (AT) and I was wondering what everyone's experience is with the optimum position when resting their 8900 Caliber watch? I left it face up last night and it was -1 sec off the next morning (still impressive!). I realize since I just made the purchase, any inferences might be a bit premature but I'd love for it to be slightly faster than slower. Any input is greatly appreciated. Thank you!

Wear it for a couple of weeks before you worry about timekeeping. These things "run in" a bit when they're new.

Thank you, will do! Glad to be part of the Omega family ^_^

The timekeeping should not change in a few weeks - if it did, any certification process like COSC or METAS would be useless.

For finding the ideal position, you need t test is=t over the 6 positions you show. Each watch is different, so you will need to find the specific positions that run fast or slow for your watch.

Cheers, Al

Strictly speaking, the person's habits return to normal after a few weeks. 😀

After testing all 6 positions on my Planet Ocean 8900 over a 24 hour period i found out that the crown down position is the optimum for keeping the best time.

Most of the modern Omega calibers with a free sprung balance and silicon hairspring I’ve dealt with often have a delta of 2 or 3 seconds at most, meaning there tends to be very little variation in timing amongst the various positions.
