hi guys i'm braking my head and buying 2nd time wrong main spring . can somebody help with rado 2797 309 can't find correct as far as i understood it should be eta 2783  and should be GR4006X but it does not fit. can somebody help to find correct?

Here it says the mainspring is 1.45 x 10.5 x 0.12 x 368mm. Which is  quite a bit shorter than the the GR4006X which is 400mm long

Cousins don't have an exact match but I would think the GR39981X or the GR3956X would be a better comprimise

What do you mean by it doesn't fit and photos would help.

ETA 2783 from Cousins so the question becomes are you sure it's a 2783?

Just looked at the Ranfft link provided by @ColinC and it shows the Rado 2797 309 as a 2773 which is the same GR4006X anyway.

No idea if Ranfft has it right... but there are 2 different mainsprings listed on the ETA2773 page - the same shorter one as was listed on the Radio 2797 309 page and the one that matches the GR4006X.

The 32mm difference in length shouldn't cause a problem with the barrel size.
