Seamaster accuracy

[Iceblue]

Purchased the latest Omega Seamaster 8800 couple of years ago and for the first 12 months it kept amazing accuracy gaining only a couple of seconds a month, but for months now it loses 4/5 seconds a day, don,t wear it everyday so on my Barrington watch winder some days, do leave overnight sometimes on top of my ipad could its magnetic cover affect the accuracy of my watch? or as anybody experienced similar. Don't really want it messed about with back at Omega yet.

Has the watch changed or has your pattern if use changed?

No mechanical watch is accurate to 2sec a month. What happens is, your pattern of wear and storage when unworn (position, duration etc) can combine to give an overall accuracy such as you describe. If this changes then the perceived accuracy takes a nose dive, whilst the watch continues to run pretty much as it always has...

Could well be what you describe only questioned it because Omega certify the accuracy of the 8800 master chronometer at 0 to+5 secs

It's out of spec so drop it to Omega to be regulated. I did the same with my Seamaster for the same reason. Was running -7 seconds per day and just needed the timing sorted.

To be fair, Omega’s movements are ridiculously accurate. I wear my PO GMT for 17 days at a time and it’s bang on throughout - doesn’t lose a second.

But from what I’ve seen with other watches, and like you say, they can be sensitive to how you place them overnight. Dial up vs crown down will affect time gain/loss and so a watch winder could be very different to general daily wear and placing it dial up on a bedside table at night.

My Black Bay 58 is sensitive to this. During the day it loses 2-3 seconds. Placing it dial down overnight it gains 2-3. Since the clocks changed, it is still accurate, dependent upon the above.

My first decent watch was a TAG Heuer 4000 automatic, and after it came back from Duvall's, it was correct to the second between clock changes. I was too young and inexperienced to realise that it was a perfect coincidence, as opposed to a perfect movement...
