gwallabie 25 Posted March 3, 2023 Hi everyone, I am planning to franken my IW377710 with an ETA 7750 and with a Hands-Set for ETA 7750 - and looking for a watchsmith / modder who would do this. As far as I understood it is mainly swapping the movement and eventually smaller mods (hope will not be needed) to the hands. Probably I would only need the center sec hand for the chrono function, maybe the three subdial hands - I read about different outcomes... Found this stem diameter description: The ETA-7750 has the same dimensions as the IWC-79320. Here are the diameters of the stems: Genuine ETA 7750 all variants (all) Hour 2.00mm Minute 1.20mm Center Seconds 0.25mm Subdials 0.17mm ---------------- New Asian 7750 (28,800 BPH) Normal ones Hour 2.00mm Minute 1.20mm Center Seconds 0.20mm Subdial 0.20mm Thanks, Cheers Share this post Link to post Share on other sites
