Hey everyone. I posted on the vintage Omega discussion page but I believe this may be more appropriate. I found this Seamaster 300 for sale on a local group and I want to check its authenticity before I go any further with it. I’ve done some research but I’m still not sure I trust my own ability to determine whether or not it’s authentic so hopefully you guys can help!
Neither. It's cal 1120.
Thanks for the insight. Does this model use 2500c or 2500d variant, do you have any idea?
Aesthetical differences are not so important for me, between the new variants of smp. I can live without the wave details on the dial and date being on the right side looks better for me. I don't know if they have any more aesthetic differences. Having a reliable movement, however, is important to me.
I believe the OP was referring to the 212.30.41.20.01.003 which is 2500D. The electric blue was a different fellow…
You’re very welcome.
Appears to be 2500D. Supposedly more reliable than 2500C though I cannot offer a comparison between it and an 8800 in terms of reliability.
If reliability is ultimately your most important criteria, you may want to also consider a sword hand SMP (2254.50 et. al.) powered by cal. 1120. Simpler, serviceable, and reliable.
Good morning, inherited this ‘Omega’ Seamaster coaxial from a friend that passed. Nice looking watch, keeps reasonable time, date complication occasionally needs reminding to change, albeit the screw down crown thread has gone and will want replacing, however, I’m 99% that this is a knock off, although they would have had the capital for a genuine one which accounts the 1% doubt.
Reasons I think it’s a fake;
The dial.
I can’t find a 250X.XX with a black face and white date indicator.
The omega symbol and logo looks too large.
I’m not sure that the hour marks are right.
Second hand looks too long.
The case.
The quality of the case isn’t great, there’s tooling marks where the lugs fit.
It has a solid back with engraving that doesn’t match anything I can find.
The solid back has 6 opening engagement points not 5.
The strap.
Doesn’t match the watch age and is stamped 455B and I can’t find an image of a genuine equivalent.
The inner clasp isn’t stamped/ engraved like my other omegas.
To be honest I’m only wearing it as my Dynamic recently encountered a feline related gravity based failure and needs repair, however as the ‘seamaster’ needs a replacement crown I thought I’d check on here before I sent it off to get laughed at.

Good evening everyone. I'm interested in this used Omega Planet Ocean (ref: 215.30.44.21.01.001) going on an auction site. I'd greatly appreciate any expert opinions or additional observations. Thanks in advance for helping me ensure I'm making a sound purchase decision!
Here are my initial observations:
- Dial and Logo: The dial text and applied Omega logo appear crisp and correctly positioned, aligning with genuine examples I've seen. The markers and hands seem correct for this model.
- Bezel: Ceramic bezel insert numerals and indices seem consistent with genuine examples. The finish and depth of engraving look good.
- Helium Escape Valve: Positioning and shape look accurate, as does the crown detail.
- Caseback: Engravings and serial number appear present, but obscured in the photograph, preventing me from looking it up.
- Movement: The photos provided show the Co-Axial movement through the exhibition caseback. The text 'Omega Master Co-Axial 8900' looks a tiny bit odd to me, but it could be the angle and lighting. Otherwise, it appears genuine.
- Bracelet and Clasp: The bracelet appears consistent with authentic Planet Oceans I've handled previously, with accurate clasp details and engraving quality.
Thank you again for any insight you can provide. I really appreciate it.
It's genuine but the condition is not that great; it's heavily worn. I would be more concerned if that was a scratch on the ceramic bezel insert between 50 & 55 or if the seller was too lazy to wipe it down before taking photos. Regardless, I would personally pay a little more for one in better condition... it's not a rare watch.
