Recommendation for Cosmic

Claven2

If you do it right, nobody will even know the case and movement were not born together.

What's the red in the 1st pic, on the dials, a reflection? I like the face, but not sure what the Cosmic actually means apart from maybe another name.

Surely the movement depicts casing, with consideration around a ring etc. I did have a hunt around for a 135.017 but saw nothing, being in aus though often we dont see much on fleabay as people dont offer posting outside the americas.

I did find this comment where @JimInOz made reference to another case being near identical packaging but wasn't sure overall, he might have more insight.. was quite a few yeas ago: https://omegaforums.net/threads/opinions-on-seamaster-cosmic-601-135-017.11829/

Intrigued as to the approach, and general sentiment... (because I'm heading down the same road, and have recently purchased some movements for obscenely low cost).

What's most important when looking to assemble a piece like this, the dial? I would have thought without a quality one everything else would fall by the wayside.

And in terms of general sentiment... forum thoughts on people piecing together a watch like this? sounds a little frankenstien, but surely its peoples choice if they have the time and skill?

But more importantly, what do you do if you wanted to sell it after, not as a ongoing income but say you were moving to a new project. From a flea-bay perspective I rarely/never see anyone stepping up and stating its a rebuilt, more 'hey heres a great watch, no history'.

BOM for that reference

JimInOz

I can't see a problem with assembling a watch from parts, as long as all of those parts are listed in the BOM for that reference.

People have been doing it with Seamaster 300s for ages.

Sorry I can't help with the case though.

Any seller should be clear with a potential buyer where a watch has been made up from parts, period or modern service.

Is there a reason you’re looking for a Cosmic case? It’s highly unlikely IMO a movement with such an early serial was originally a Cosmic. If cost isn’t an issue you could obtain an extract against the movement to see what reference if was originally.

Yes, I have a 1966 cal. 600 movement which would be a period correct movement to replace the 1960 movement that came with the Cosmic dial that is pictured. That combo from what I gathered went into a 135.017 case unless you know of a different fitting case.

The fact that that dial fits on that movement doesn’t mean they were supposed to be combined when looking at the serial. I agree with @Davidt - the serial of your cal 600 points it to ~1960/61, Omega started building the 135.017 in 1966. IIRC, the 601 was built much longer than the 600, so the 135.017 might not have come at all with a cal. 600 originally.

Mind you, this is all just information that’s relevant to you if you’re really fastidious. Honestly, if enjoying a watch with the right looks is your main concern, there’s nothing wrong about using that cal 600 with the early 60s serial for your Cosmic.

Sorry I miss typed it was supposed to be a 1966 ca.601 not 600. I had the 601 sitting when I came across this dial with the 600 and the price was good enough for the combination of the dial and the hands that I thought of the movement that it came with as a bonus. Now I have to look for an early sixties dial to go with that 600 movement as well as the 135.017 case!

How much of the movement servicing do you do as well?
