just received watch yesterday. Having trouble finding info on this calibre 613 for my omega Geneva. Appreciate if I can get some information/specs on movement please.

 

Well, first piece of relevant information is that the 613 is a date movement, so....

Are you sure it's a 613?

 

I believe so.

 

Well, looks like you have yourself a franken watch. In any case, the movement is a manually wound movement with date, 12 1/2 lignes in size, 17 jewels, 19,800 A/h, with a 38 hour power reserve.

Generally speaking they are reliable and accurate if not in terrible shape. Your watch looks like it has some rust, may be in need of a service, and has had some parts replaced from a donor watch I suspect. In a word it looks rough.

Hope this helps.

Cheers, Al

 

Redone dial also, and as already told the dial should have had a date window if it was to fit the caliber 613 with date. Do you have the reference number form the inside of the caseback?

 

135.012 (135.0012) should have a caliber 601 movement inside.

 

Can a 613 even fit in watch?

 

Same size I think, same model series, the date function is the difference

 

Ok thank you for your help. Will not be keeping watch.
