Hi everyone here,
this is my first post so bear with me when I’m making mistakes.
See attached some pictures of an old Omega watch.
It has been in the family for 50 or 60 years, it still runs and works although it’s running a little behind, about 20 minutes a day.
I love it because it’s from my grandfather.
Can anyone give me any information about it?
Also, when I open it, you see the springs that look to me as if they are not the right ones or too big, could these be the reason why they’re running behind?

Thanks

 

Your watch is most probably a 28.10 RA PC SC. The codes indicate that it is a bumper automatic, it has shock protection and central sweep seconds. If the rotor is moved over to the other side showing the balance you will see the shock protection. I have a very similar piece with serial number 10'910'959 which is close to yours.

 

Apologies for second post. Here's a link to the Ranfft pink pages with more detail on your watch.

Thanks a lot, looks like a brother from another mother
What do you think about the springs?
They look weird to me.
Who is repairing these?
I know Omega has a service center in Switzerland, but there has to be some support in the US…

 

If you follow the link you will see what the springs should look like. I'll attach a photo of my big brother 30.10 RA PC to show springs. These were the very first Omega bumper autos. Later versions covered up the springs. Do not send your watch to Switzerland for service, it will come back as an unoriginal watch that runs really well. I sent a private message regarding service.

 

Very similar to my watch although mine is a sub second my case back is also Wandsworth very similar to yours mine was made in 1944 .

 

The case on your Omega was made by the Wadsworth Case Co., not part of Omega to my knowledge. They were a major supplier of cases to Omega. If Omega had given this model a name, it likely would have been printed on the dial. Your watch should be serviced NOT by Omega, but a specialist who is expert in working on antique mechanical watches. Don’t take it to the jewellery counter at your local Wal-Mart store to have it serviced. Give us an idea of where you live, and maybe someone can recommend a shop.

 

I live in Massachusetts and already got a recommendation but would appreciate maybe a second one so I can compare.
No worries, I’m not gonna bring it to a Walmart repair shop
But I was thinking of sending it maybe to Switzerland but the other expert on the forum recommended not to do that.
Do the bumper stop springs look OK to you?
Could this be the reason why at the watch is going 20 to 30 minutes behind per day?
And it doesn’t look like it can keep the energy for more than 6-8 hours, in the morning I have to reset the watch because it stopped overnight

 

Those bumper springs have absolutely no bearing whatsoever on the time keeping of your watch. How long it runs overnight can be affected by a/ how much winding you give it if winding it manually, or b/ how long you wear it through the day, or c/ how active you are when you wear it, or d/ condition of the mechanism. I recommend that these older bumper automatics should be fully wound manually at the start of a period of wearing it, then winding it manually again if/when it stops. The automatic winding on older automatics with the bumper mechanism falls short of modern automatic winders. A competent technician can fill in the blanks for you.

 

Thanks so much for your reply, I’m embarrassed to say that I had no idea that I can actually also wind the clock up
I just assumed that the bumpers would do all the work…

 

It need service cleaning and oiling to make it run accurately. I would stop wearing it until it's serviced and then enjoy it for many years in good health !

Oh and welcome to the Omega Forum. Lots of help here from serious collectors.

 

That’s a masive six-eater subseconds, I didn’t think they got that big until the 26x series.
