Genuine or not?

Hi. I'm not a collector, but only because of lack of cash. About 15 years ago I splashed out on a watch to celebrate a promotion at work. It was sold as a genuine Omega Seamaster 600, boxed, Omega buckle and dated as early sixties. Browsing on line recently, I realised that it has a big flaw - it lacks the seahorse design on the back. So, is it a fake, or is it genuine but with a replacement back, or did Omega ever make them without the design? Grateful for any info. Whatever the outcome, I love this watch!View attachment 1132531 View attachment 1132531

Looks OK not all watches had the hippocampus on the caseback.
Omega made flat casebacks for engraving for 25 year service and the likes. They even marketed as the special occasion, anniversary or graduation watch in the time the above watch was released.

So inside the case back will tell you/us more.


Plenty of adds like this in magazines around graduation time

Ah, I see. Knew this was the place to ask. That's really helpful Standy - it's always felt genuine to me, and you've cleared away any nagging doubt. Thanks so much. This site is going to worry my bank manager.

Do you have the rest that came with it ie: box

You need to get it serviced if you have had it 15 years without one. Find a independent watchmaker with a Omega account. (Do not send it to Omega they will replace parts to make it look like new but ruin the vintage charm and value)

Looks quite genuine, I'd say a reference 135.011 with a caliber 601 from about 1965 or so.

This model didn't have heavily stamped logos on the caseback, more often just lightly etched.
Owing to time, wear and the effects of sweat induced corrosion, the markings were often worn away.

A nice keeper with a bullet proof movement (if properly serviced).

It was an entry level piece in the 60s range. Looks perfectly genuine to me and there is a theory that the full Arab number dial was a UK market special order as that is where those are seen most.

Yes, I have the box. It was serviced a few years ago, and has had a replacement bar thingy that secures the strap.

Thanks for the info. A service is on the agenda post Tier 4.

Just out of curiosity, as I have no intention of selling, any idea of value?

£500 or a touch more or less. Differs from private to dealer selling.....

But someone in the UK might have a better handle.

Maybe £300-400 as is, £500-600 when freshly serviced (a service runs to circa £200-250 at an independent). That would be in a private sale ie ebay. A dealer would offer less and ask more, sometimes a lot more.

ps don't take the Seamaster bit too literally, these were barely water tight when new, now it will be very unlikely to hold water out. The 600 part is not a depth rating of any kind, it refers to the movement within.

Thanks very much. I'm aware of the waterproofing or lack thereof - don't take it anywhere humid or it steams up.

I think £300 would be a good price as a buyer at the minute. I like these Arabic dials and was bidding on 2 or 3 last year. I think I went up to £325+/- and didn't win a single one.

It depends on dial condition. If it's good without blemishes I think £400-500 unserviced is about right at the minute. If it has damage/stains or heavy patina then £300 is right.

Yes, me too. Just bought a nice 1940s piece by JW Benson with full Arabic dial, but that's for a different forum...
