Posted this a couple days back but not in the vintage Omega thread.

I’m really interested in a vintage omega constellation from the 70’s. It looks and is listed to be in great condition. However, after reading about the movement it sounds like there aren’t a lot of people out there who can service these anymore and parts are hard to come by. Does anyone have someone that services these particular movements well and actually has spare parts if needed? Any thoughts or suggestions would be greatly appreciated!

Thanks in advance.

You’re going to have to post both some pictures and the reference number for any meaningful responses otherwise people are guessing which watch and movement you’re looking at

Thanks, good point. Just replied with a picture of the movement and the reference number is 198.0047

Parts for these are now basically Unobtanium. There are ways to keep them going but that isnt a road I would go down willingly personally. If you must go early 70s electric, the F300 hummers from the same era are slightly easier to keep running with several service options so you might want to look at that. Quartz movements from the same era also have parts and servicing problems so are also to be avoided.

Following on from @padders, if you’re looking for an electronic watch, Cal 1250 is reliable and around (and affordable) but buy one working properly, repairs can be costly.

The model number is frequently 198.*** and, whether Constellations or Geneves, are chronometer rated.

I collect Accutrons and Omega f300's. Whenever buying one of these watches always factor in a service that will cost between 250-500 depending on parts needed if any. I know of five or six highly reliable guys that have access to parts and are honest in doing repair and servicing. Parts for these watches are not as plentiful as before but are still available. They are beautiful watches and deserve a place in your collection.

Hi,

I just purchased a Constellation 1230. It is running smoothly, but loosing about 6 seconds over eighteen hours - well out of original spec. It's hard to find information about these.

I have Accutrons and am usually able to adjust the rate to within a second a day. Do you know how to regulate the Megasonic?

Thanks!

Pete
