Omega Seamaster Seaweed - Authenticity

Hi everyone,

I think I am ready to pull the trigger on an Omega Seamaster Diver 300M "Seaweed", and I'd love to get some opinions from the community regarding its authenticity.

I've compared it against photos online and everything looks correct to my eye, but I know there are many experienced collectors here who may spot details I could miss.

The set comes only with the box, mini-pouch/box, card holder and warranty card.

If anyone is willing to help, I'd really appreciate it.

Thanks in advance for your time and expertise!

Well nothing jumps out as fake. Usually the balance wheel is a big tell but that one doesn't look off. If you can access the cards, you can use the Metas code to check the watch appears on the relevant website. If it does, it isn't fake.

I agree, but I've also seen fakes with a balance wheel that looks genuine. It really depends on which movement they use.
Some of the superclones even run at the same 25,200 vph.

The clones are getting better and better, so the small details are often the biggest giveaway.
With a loupe, how is the finishing on the hour, minute, and second hands?
They should be flawless.

How does the bracelet feel?
The clones I've seen tend to have very poor/flimsy bracelets that don't feel smooth.

How does the crystal reflect light?

The crown guards on the fakes I've seen, seem to be shorter and thinner than the genuine ones.
(On yours, they look correct.)

Do you have a better close-up of the movement?

Sorry for my late reply, I was busy with work the past few days.

I hope these images are able to help!

The bracelet I guess feels quite good, doesn't feel flimsy at all.

The crystal doesnt seem to be very reflective, looks quite clear from diff angles!

Ahhh, thing is it only comes with the warranty card and serial number matches.

You should still call an AD, and they can run the serial number through the database.
Based on the photos, it looks genuine to me.

Buy a superclone and leave your worries behind. How much cheaper is this than a new one? Is all this doubt worth it?

I’d rather own the genuine watch than buy a superclone. Saving money isn’t worth giving up authenticity, provenance, and the confidence of knowing what’s on my wrist.

I think stamplicker’s point is that whatever money you’re saving buying preowned is offset (in a bad way) by having doubts about authenticity. Buy new from Omega and know for sure it’s legit—or (the gist of his/her comment) buy a super clone and know for sure that it isn’t. Doubt has a cost of its own, and as supportive as we can be at the forum, no one here can give you 100% certainty based on photos.

We always say “buy the seller”—if this one doesn’t allow returns (giving you time to take the watch somewhere to get it authenticated in person), then you might want to look at a trusted preowned dealer (there are several) who will, and who will also stake their hard earned reputation on only selling pieces they’ve authenticated themselves. In my experience, doubts like this don’t get better over time—they only grow. You want to know for sure. And the clones have gotten very very good.

Ah I got it, my apologies to stamplicker as I misunderstood what he/she meant.

Much agreed to what you have shared, the difference is quite a fair amount but the pricing isn't in the 'too good to be true' kind of range.

I think the Seller might be legit as they have a nice track record and reviews on the Timepieces they've sold, and they are registered as a pre-owned dealer as well.

Just want to be safe and seek a third opinion here from the community before I pull the trigger.

Thank you for pointing it out and sharing with me, really appreciate it~

I still have not seen or heard of any fake using a 25,200 beat. If you have, it would be very helpful if you can support this with confirmable information.

Just in general regarding "superclones:" from what I have observed, every single one of them has looked "indistinguishable" from the real thing only to people who aren't very familiar with these watches. Put them in front of a group like omegaforums.net, and suddenly people start pointing out all sorts of tells.

An absolute dead give-away for me is the 'pallet fork'. Sadly, no one really ever takes a picture of it, but no has cloned a Coax escapement yet (and based on how much trouble Omega had, and how there basically isn't even a good free-sprung balance yet, given how much Rolexes go for, I doubt we'll ever see one for a very long time), so just looking at the pallet fork is a dead give-away, no matter how much they try at everything else.

I’m being cheeky, but one could argue that when the superclones get tremendously good (pallet forks and all) it will be a development that goes entirely unnoticed, as we won’t be able to tell them apart from genuine watches and will simply green light them. That moment may well be in the past. How would we know? 😀

So the development costs of a movement are REALLY quite high, getting them to work well enough (particularly now that even super clone owners are buying timegraphers) is really difficult/etc. Because of that, you have to recoup that cost SOMEWHERE.

You obviously can't charge $10k like Omega does for a Coax watch, because why would someone buy that when the real thing is the same price? SO you have to figure out how to SELL them in decent enough quantities. REP sellers/buyers/resellers are, for obvious reasons, not particularly good at keeping secrets/keeping their word, so this sorta stuff gets out REAL quick...

I got a feeling if they actually were selling a reasonable coax movement, the rep community would be bragging about it all over reddit (99% the quality, 10% the cost) before they finished manufacturing it.

EXACTLY this. The rep producers can't do it for cheap, but if they could there's no way they could keep it a secret.

I would also like to see a so called Superclone Omega with a genuine free sprung balance. I've seen ones with balances faked to look free sprung (ie fake timing weights on the wheel) but not undetectably to those who know what they are looking at. The watch shown above looks fine to me and until I am shown otherwise think the threat of the undetectable clone is overblown. At least in the Omega sphere. I suspect things are worse in the Rolex, AP or Patek world though where it is more worth their while.

I was certain I’d seen one of those VSF superclones with the same VPH hooked up to a timegrapher, but I might be mistaken, as I can’t find the video after a quick search.

According to ChatGPT, the latest Dandong/VSF clones use 25,200 VPH (3.5 Hz), although I cannot confirm this.
