slickdick Posted October 25, 2010 Report Share Posted October 25, 2010 No, Crown position is different. It can be done, sure, but not easy. Quote Link to comment Share on other sites More sharing options...
sander Posted October 25, 2010 Report Share Posted October 25, 2010 Easy swap? How handy are you? The first one I did took me more than 60 hours. Now I know how to do it, it takes me about 14 to 15 hours. A few difficulties: The pushers won't work with the movement and need to be modded. The crown can be lowered (it's not a must) but the pushers still needs modification. A complete new inner case needs to be made. If you do not have the gen hands, you need to broach the chrono hands and make new hand tubes for the hour and minute hand. (the rep hands sizes are 1.20mm for the minute and 2.0mm for the hour hand. The movement needs 0,9 for the minute and 1.20 for the hour hand.) 99% of the time the date window needs to be painted matte black or matte silver because the movements normally come with a polished window. I assume you have a gen dial right? If you are handy, it's a fun project. Go for it! If not, it's a waist of money! Quote Link to comment Share on other sites More sharing options...
