mac83 0 Posted May 13, 2015 Hi guys, ive just bought a frank muller crazy hours with a gen dial, im looking to change the movement from the 21j, can anyone tell me what options are available. Share this post Link to post Share on other sites
GenTLe 1,509 Posted May 14, 2015 Crazy hours has a modified movement to make the hour hand to "jump" in its "crazy" way of work. No other movement will do that. Anyway I believe that a handwind and a automatic movements are around... I still have to open it to check, but the one I got from silix (the more expensive one at 90$) makes the noise of a rotor inside when manipulated. Share this post Link to post Share on other sites
Genius 281 Posted May 14, 2015 Mine is a 21j and you can hear the rotor. If you want to mod it just remove the rotor and you got yourself a hand wind that will be silent Share this post Link to post Share on other sites
