Hi, there is a wonderful but also quite expensive Omega Seamaster 600 which has a caliber 600 and ref. 135.011. According to the omegawatches database that combination does not exist. Also I believe that 1968 as the date of the watch seems to be quite late for a caliber 600. The serial number of the movement starts with 214. Looks odd to me. What do you think? Thank you and Best regards RS

The Omega database is incomplete. We would need comprehensive photos to help you with your question.

Hi Dan. This is the link to the offer on chrono24:

You could see the photos there. I am interested because I believe that the caliber 600 would be something rare. Normally I guess that there is caliber 601 or above in the Seamaster 600. Would you agree? Thank you and Best regards RS

If you can, post photos, not links, so someone stumbling onto this post in 10 years will know what watch is being discussed.

As far as I can tell, the 600 and 601 are about as similar of movements as I could ever imagine to see. A 1968 watch with a 600 would be suspicious, as it was only in production into 1964. I find myself wondering if this was a replacement movement at some point in its life.

What is very interesting here though to me is how rare the 600 seems to be on the internet. It was quite hard to find any real details about it outside of a handful of listings, and seems much less common (and was made for fewer years). But I'm guessing whoever the person who swapped it (if they did!) just had it on their shelf, or it came from a donor.

I didn't click on the link, but according to the OP, the serial is 21M, which would be 1964, not 1968.

Well, that 21 million comes from the movement, which would obviously be changed if the movement changed.

The seller on C24 is the one claiming 1968 (though, looking at it in English, it looks like it is an 'approximation'), but I have no idea how they could know.

I DO know that every single watch of that reference that I can find (that has a movement specified/pictured) is a caliber 601. So: "rare combination" or "swap" are the two options AFAICT.

Hi, thanks for your contributions. I really appreciate it. 1968 is obviously wrong. However I agree that the combination of ref and cal is very unlikely and thus probably a swap or sth similar. Also if you look at the caseback this looks quite odd, like being painted. I think I will keep my hands off this watch. Best regards RS

I'd also say that the crown is also not original to the watch.

For what it's worth:

I have an almost identical version to the one you posted above. I purchased it off the original owner who chose this interesting Omega 'Serpentine' bracelet when he bought it back in the late 60s

Seamaster 600.
Serial No. 220xxxxx
Reference: 135.011
Year: 1965
Cal: 601

Here are some examples with the crown I would expect:
