10sec ahead per day for a 3y Globemaster?

I'm new to the forum and a newbie when it comes to watches. Hope this is the best place for this question.

This week I bought a 2nd hand globemaster on chrono24 (the seller is Malaysian and well rated). The warranty is dated February 2020. It looks new but takes a 10 second ahead per day. In your opinion, is this an acceptable delay for a globemaster who is 3 and a half years old? Should I try to send it back to the seller?

Thanks for your help :-(

Send the watch back. The Chrono 24 warranty is not an Omega service centre warranty. Send it back to Chrono24, and there goes your opportunity to return the watch for a refund. You likely will never be happy with it! Or send the watch to an Omega service centre and spend what you saved by buying the thing from Chrono24, by having Omega service it. You want a new watch with an Omega warranty, buy new!

If it were sold by an AD originally it will still be covered under warranty as the standard coverage has been 5 years since mid 2018. It’s worth taking it into an AD to see what they say.

But only if the owner has the original factory warranty card filled out by an AD or an OB, I suspect!

Yep agreed but it is a possibility.

Seriously? I admit that I am rather used to vintage watches. I would, accordingly, not complain about 10 seconds fast per 24 h. The specification as new (chronometer specs) is -4 to +6 seconds per 24 h. I would think that 10 seconds are not all too far away.

I have to agree. I'd live with +/-10s a day. It'll fluctuate anyway, day-to-day, depending on wrist position, winding etc. Just stop measuring it and enjoy.

I have the same opinion. 10 sec per day sounds fine to me.

Have you tried using different positions to store it at night? I find my Seamaster 300M gains 5 sec face up overnight but loses 3 sec when crown side down. I alternate and it evens out.

Many thanks for your answers.

I can absolutely live with +10 sec a day. What I'm afraid of is having acquired a defective watch for such a big amount of money: I guess full service can't fix everything (or does it?). It's only 3 years old and is supposed to be "master chronometer certified", etc. The guarantee card seems to be fulfilled by a non AD...

For the rest, the watch is fantastic and seems to be new.

Something to consider:

Did you fully wind the watch and wear it before checking the time the next day? You can easily get bad timing results if the watch is not fully wound. And just wearing it without first winding is unlikely to fully wind the watch unless you are really active.

If you gave it a lot of winds (50 turns of the crown or so) and wore for a few days before testing and it averaged 10 sec a day, then it does need to be looked at. If it is steady, a simple regulation may be enough. But if it is highly variable, something is off.

This isn’t a vintage watch, so should be < +5 sec/day.

If this was a vintage watch, I would say +10 seconds is acceptable, a newer watch with a METAS cert should be better in mu opinion. You can create an account with Omega and look up to see that watches original METAS test results. with that info you might be able to make a more informed decision.

Indeed, 2.6 sec/day on the METAS test results.

I wounded the watch immediately. It was also my feeling that it shouldn't be >+5sec for a 2020 watch. Since I received it only 2 days ago, I will follow your advice and check if the lag is stable or if it is variable. Thanks!
