Hello to all...and I need some help about a Seamaster vintage

Hello everyone, I have just launched my profile in this forum, I am from Spain and I hope to be able to learn many things about Omega watches with all of you, I hope you can forgive my English because it is not the best in the world. Since 1999 I have been a happy owner of a Seamaster 50th anni (movement 1128), but what has brought me to create this thread is a slightly older model. I'll get to the point:

I like to tinker with watches and a couple of years ago I started doing my own restorations (I call them "rescues" jej), then, a couple of weeks ago I found a vintage Seamaster on a Spanish trading platform, I couldn't resist its charm and I acquired it.

And this is where my doubts begin: the watch has a "10k gold filled" finish (marked between the lugs at 6 o'clock), which makes me think that it is a model that someone imported from the American market, not a model that was originally sold here in Spain or Europe. Therefore I do not know this type of case well, I have already removed the movement (a 490 with serial number 14.xxx.xxx which I believe dates the watch as manufactured in 1955), but I am not clear if the bezel is fixed , or if it is under the gold foil that covers the entire box, because I don't see any slot to put the opener in to be able to extract it.

Another question is: the threaded steel back does not have any "Seamaster" logo, or a "waterproof" legend either, on its external face, it only has "10K G(old) F(illed) Bez(el) Steel Back" engraved in small fonts; and internally it has the reference FX6294 marked (which is also not common in European market I think), but what intrigues me most is a kind of logo that has what appears to be a "J" crossed by a hand or arrow, and on that logo is stamped a F4072 Does anyone know what that logo is about? A mark of the typesetter or the company that did the gold plating?. Back or case has no gasket either and I must to find one too (I think right measures could be inner 29,75/outer 31,75 mm).

My idea (apart of a full service of the movement, clean the dial, hands, etc) is to redo the gilding treatment of the case and the crown, first I need to refining the case and then applying a gold plating over the old filled gold (or what is left of it after refining the finish of the case), but for that I must know if the bezel It can be removed or not, and if it can be removed I must know how. I share some photos (keep in mind that the watch is in the condition it arrived to me, still very scratched and very dirty...I promise to update my restoration progress) this are seller pictures from the platform where I bought it:

The "10K Gold Filled" legend btween lugs at 6hrs.

Movement works but it is very very dirty, partly because was no gasket there. Needs a full cleaning and service.

Steel Back marks:

this is the "J with arrow" logo that I would like to know about:


Any help will be appreciated and I thank you in advance gentlemen for any help you can provide me.

Hello and welcome. If you need, I know some crazy folks in Spain for restoration.
If the gold layer is thick enough I think you could obtain some good results by a gentle polishing.

Thank you very much X350 XJR !!! That is very valuable info, you have clarified my most important doubts !!!. So that "J" logo belongs to Jonell and the bezel is not removable in this case, niiiice to know both things !!!.

Yes, you are absolutely correct, the balance bridge is marked with OXG. Sorry about my ignorance, I didn't know what that OXG code meant, I thought it was some code for the replacement of the part or something like that, but now I see that it is an import code to the US.



Thank you very much Kwijibo. Could you tell me who those crazy folks are?, I may contact them (although my intention is to try to do the restoration myself).
Unfortunately, the gold foil has peeled/worn off on all 4 lugs and in some places on the case at 12 and 6 o'clock (just like gold plating), so I can't just polish it, I have to give it a gold plating to cover all the damaged areas. you can see how the gold layer has been eroded

Thank you very much gentlemen, your answers are very helpful to me.
