I don’t think there is anything compatible between the two. I believe the Omega 30T2 is a 13 ligne movment where the 6497 is a 16.5 ligne movement. They may have similar bridge configurations but that is about it.

Does anyone know if this movement is compatible with the Omega 30T2? Looking for a new movement for a vintage Omega and they look very close in specs.

[...] Well, the wrist watches are based on a ETA (Unitas) 6497. I remake the mainplate and all the bridges to meet my standards of fit and finish. I refinish the [...]

There should be a little screw near where the stem enters the movement. That screw should release the stem, but don’t turn it too far because it will release other things too, probably 1 full turn or so should do it.

Hey, found your article while searching on how to remove a unitas (clone) from a uboat case I have. I’m huge watch enthusiast but can’t really say I know much about the guts themselves.

can you tell me how to remove the crown shaft so I can remove the movement from the case? I can provide a picture that doesn’t make sense. the only thing holding the movement in is the crown shaft and I’m not sure how it disconnects.

I want to buy a real unitas movement and redesign the face for a custom piece in the case, but I’m mildly in over my head

any help would be appreciated.

thanks!

How can the value of a family watch be determined? It is an Alliance Horlogere cira 1930′s-1940′s. Mechanism still works.

ETA only supplies movements in large quantities. A good place to get a base movement for a project is from http://www.ofrei.com. They even have kits with dials and cases. The technical drawings for case and dial requirements are available in the technical guides available from ETA o their web page or from Otto Frei as well. In fact for information on the different grades they would be a good source as well.

As for add-ons, there isn’t much available for the 6497, you’ll have to make any complications yourself. There was a version of this watch with a date many, many years ago, but I have yet to find any parts for it.

Case design is generally jewelry work and I have no experience in it at all, nor can I recommend a good book, but if you know how to work metals it would be pretty straight forward.

Best of luck!

Hi Peter,

I am looking to design and make my own case and dial for a ETA 6498 movement. Can you advise where i can learn about the different grades of movement offered and what the benefits are of each ‘upgrade’. Can you also purchase different parts that bolt onto the basic movement but add to its functionality (ie date, power reserve that kind of thing?).

Also where is the best place to get these movements from, do ETA supply them direct? can you recommend a text book that details case design? Thanks for your help.

Joby,

The 6498 is like 99.9% of watches on the market today. The hands are friction fit onto the post. You could remove the seconds hand and attach a disc without any problem at all. There is no pin you need to remove or anything.
