gwallabie 25 Posted March 3, 2023 I am planning to change the asian movement in a ZF IWC 377710: ZF IW37710 to an ETA 7750 (with an IWC rotor if I can source one) . Found a Hands-Set for an ETA 7750 , it claims to be a set for an IW3777-01: ZF 3777 (01) Black Dial Does anyone know if the Hands-Sets are exactly the same for both movements, or are there any differences like in color or size?

Teetertank 0 Posted May 15, 2023 Potentially interested in doing this too. I believe you're looking at the right set to replace the rep hands, as you've probably already found out, there is a slight difference in the collet size one one or more of the hands between the Asian and Swiss movements. I think it's the chrono second hand which has a slightly different pinion size. Regarding the 3777-01 vs 10 I believe they are the same as I've seen the same reference used when checking for the gen hands. Share this post Link to post Share on other sites
