Vintage Omega Seamaster caseback question

[77T]

I had never seen such a caseback engraving before and asking if any vintage Omega experts might know about or have seen similar casebacks.

The watch is in bad shape and looks like a a similar case as a vintage Omega Automatic I currently own. Mine is a 1965 and this looks like that era model.

But it is not a dive watch for sure - looks like a model that fell between the dive line and the Deville models. So did Omega use the Seamaster name on some "non-dive" watches?








Any insights are much appreciated.

Omega introduced the name "Seamaster" in 1948 to denote their line of water resistant watches. Most of the early Seamasters were dress watches, and many of them continued to be dress watches even after 1957, when Omega first introduced their trifecta: the Seamaster 300 for divers, the Speedmaster for racing drivers, and the Railmaster for engineers. The DeVille was originally a Seamaster line before becoming its own.

As far as your specific caseback, I couldn't say. The rest of the watch looks like it took a beating ... water damage, perhaps (although that's just a guess).

Like Frank said, that's definitely what the Seamasters of that era looked like. That's why I think the modern-day Aqua Terra is the closest thing to the old Seamasters.

I also can't comment too much on that exact caseback, but it looks genuine to me from what I've seen.

Some came with no Hippocampus, some were engraved, like.your example, some are embossed, mostly De Villes.

Thanks very much guys. Yes I see evidence on the dial that moisture got into the watch. It has a generic crown (and probably gene in stem, too). I knew the dial was authentic and original since it was a one-owner watch from new, but the engraved caseback was throwing me a bit (vs. embossed/stamped).

Will get it opened at my watchmaker's today (hopefully the back isn't seized to the case).

That explains why the case on the Seamaster looks so similar to my old non-waterproof Omega Automatic.
Here's a pic of mine and the case dimensions are the same as well as the lugs.
