Ended up purchasing this restored gold filled 351 bumper from a local watchmaker. It it is in nice condition and is very accurate. After doing some Googling and info from forums, I am left wondering if there are some incorrect aspects to the watch. Namely the presence of a sub dial on a 2577, and if the back cover is correct (is the rest of the watch a 2577). If there are some minor "franken" parts in the watch it doesn't really worry me in the wearing, but I would just like to be confident of the originality if in the future I sell it, or pass it on. I would appreciate any comments.

 

Cal 351 doesn't have a subseconds.

 

I suspect there has been some "gathering together of parts" to produce this watch (well, I don't really suspect, I know!).

A correct 2577 is shown here.

As a collectable it's worth about $5, if it was me I'd return it.

 

Certainly wouldn’t bring the price a completely correct and original one would, but FIVE DOLLARS? You can enjoy it until you decide to sell it. It’s up to you how you portray it if you sell it. It’s clear the seller didn’t tell the whole story. Enjoy it for what it is. Perfect ones are rare.

 

Next time you should google before pulling the trigger and if things dont add up just dont buy. As other members have mentioned you have a movement that doesnt exist (351 w/ small seconds) and that I would consider worthless from a collectors point of view.

So made up movement, incorrect dial for the reference, and crown is from a Constellation.

 

Ironically, the connie crown may have a little value!

If it works, and you like the look of it, keep it and use it

As others have said, if you view this as an investment, you’re going to be dissapointed in the long run, so return it quick

Edited to add - if its also a genuine Omega strap ( and buckle?), then these will also have value

Can you tell us what you paid for this?

 

Thanks everyone for your replies. I bought it because it looks good on (and is very accurate). As commented above models with the 351 do not have subdials, so does this mean the movement also has been modified in someway to operate a seconds subdial.

 

Likely that the dial & adjacent part of the movt. have had cal.351 parts added to the back of the movt.
You can see from this link that cal351 had associated variants with subseconds. http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&&2uswk&Omega_351

 

Note the different coloration between the barrel bridge marked 351 and the rest of the movement.
I believe the rest is some variant of the 28.10, perhaps the cal.344 (updated 340, 342)? I'm not sure what else in that date range would accept a 351 bridge.

I don't feel there's anyway to modify a sweep center to a sub, I feel the 351 barrel bridge is the oddball.

Remember, I just tinker.

 

Frankenwatch for sure, but actually looks quite good!

 

Putting a 351 barrel bridge on (for example) a sub-second 340, 341, or 342 would not require any other changes. But trying to take a complete 351 movement and converting it to a sub seconds movement would require a LOT of work and swapping of parts. The barrel bridge colour tells me that this bridge is a replacement.

 

You can add a center second, if you like...

 

That is the polished end of the centre wheel arbor. Not the tip of the centre sweep, pinion.
