Hello everybody.

I have the chance to buy this 2446-1 bumper with black dial.

From the movement # on the I see that it's a 1947 watch.

Is the 351 movement correct?

Any inputs before I shot the trigger?

Thanks a lot

 

I myself have just ordered an Omega 2446. Of course there are seniors on this forum who can guide you better. Based on the minimal info I could collect from the info:
1. The movement doesn't look well oiled and clean/serviced anytime recently
2. Serial number suggests that it was made between 1947 and 1948
3. The indices don't match the omega vintage catalogue, but Omega often misses some references on their vintage website
4. Crown seems a bit rusty too, can't have a glimpse if it is signed or not

Overall, you may find better Omega if your research more. Noit to discourage you, just my opinion.

 

The dial looks okay to me except that it has lost almost all of its lume. The hands seem to be incorrect (edit: this is incorrect) , though, which is the biggest problem I can see (and probably enough reason to keep looking unless you just really love the dial). The case is not in amazing shape, but it's 75 years old. It will almost certainly need to be serviced, so factor that into the cost, which is of course what it all comes down to. What's the asking price?

 

Caliber 351 seems a bit early for this serial number and reference, 2446-1, one would typically expect the forerunner of the 351, caliber 28.10. IIRC the 351 came in 1949 with a different winding weight design. Could be some overlap here as serial numbers are a somewhat inexact science without a factory extract to confirm.

Dial looks original but missing lume as are the hands which I think are correct.

 

I defer to @X350 XJR who is much more experienced than I am.

 

Is this an Australian variant?

 

I have long been under the impression that the 28.10 had a tongue-shaped spring located atop the automatic system top bridge located where the arrow indicates, and exposed bumper springs. The subject movement looks to me like a calibre 351. If you look closely at the bridge beneath the rotor and close to the rotor’s edge, calibre 351 shows.

 

That serial is actually nearer 1949. The 3 digit naming came in pre 11m (circa ‘47-48) so the movement is fine for the era. A later movement may have been dropped into the case of course. The OVD shows the 2446 as being introduced in 1946 and hosting a 351 but it’s true the very first must have been the older exposed spring version without that name. The model seem to exist up to the early 50s so nothing there seems amiss with the movement at least. The dial is harder to judge since I struggle to stand on my head!

 

The watch has some issues, but the dial is kind of cool looking, I can definitely see the appeal.

 

If those with the knowledge are looking at this thread please comment on my Bumper. It is the only bumper I own or ever owned so can only compare to info on line.

I bought it as a 351 but cannot see that marked anywhere so maybe something else ?
1946 vintage ?
Maybe not all original ?
Looks a bit grubby and unserviced, but keeps good time, not sure if its worth getting it serviced ?
Based on price paid, is it worth £300/$300 ?

 

It is much better to create your own thread than piggyback onto an existing one since it gets very confusing but since you ask it is unfortunately not all original. The movement is fine, it is the one that became the 351 in 1947 but in this case dates as you say to ~1946. It was known as the 28.10RA SC PC (you may see some of this stamped under the balance).

Note it says Seamaster on the dial, this model wasn't a Seamaster, no Omega had that text on the dial until ~1949 proving that this has been redialled or replaced.

 

Thank you

I do have a GREAT watchmaker handy which I hope will do another miracle with this dial, so let's see what happens. I paid the watch in the range you mentioned so hopefully I will get a decent watch at a correct price.

 

I don't think so, having foud it in Italy.

 

Thanks for the advice and information, much appreciated

 

I've had the watch serviced and the dial restored and this is the result.

Although my pic isn't very good and can't show properly the condition of the dial, I can assure you that it's much better in realty

 

That's amazing. Can you tell us who did the relume job?

 

Sure - Roberto Tarabella here in Italy
