I purchased this mid size SMPc

Reference 212.30.36.20.03.001


It's losing -6 overnight so I'm wondering if its a real watch or not. Bracelet is non OEM I added it myself.

Thanks a lot for your help!

Perfectly genuine but it needs a service. It’s now at least 8 years old. Maybe as many as 14 years in fact. It’s time.

Thanks for your answer, I opened the caseback myself and then screwed it back on well but without relubing the gasket, it was open for 30 seconds, is the water resistance compromised?

Yes. Another reason to service it. Did you buy it privately or from a dealer? If the latter perhaps you have some recourse.

I purchased it from a private seller. Ill make sure not to put it in water until I get it serviced, thanks a lot.

An Omega official service isn’t cheap but you might consider using an independent ideally Omega authorised watchmaker. That will be much cheaper.

Omega service also takes a while (think in terms of months, not weeks). But it comes with an Omega warranty and all the peace of mind (re authenticity) you could ever want.

Have a 2531.80 I bought from a private seller 20+ years ago. Could always tell when it was losing time, it was time for a service. Found a local watchmaker and took about six weeks for a full service. Price was reasonable, around $400/$500 for everything.

Remember, getting it serviced around every seven to eight years will extend the life of the parts, clean out any older lubrication, and finds out if any parts might need replacing. Unless it's a newer watch under warranty, usually will take any neo vintage watch to a local watchmaker.

I remember when the no wave dial one was released and how polarizing it was. Have yet to see one in person, but looks great in the pictures.

It's one of those watches that looks way better in person.

To be honest I think this generation is the pick of the smp300s. Simple and refined design

The black date wheel on the blue dial really jars for me but otherwise it’s a pretty well resolved design. As such I prefer the black version where that isn’t an issue.
