Yaakov Asher Sinclair Posted May 10, 2007 Report Share Posted May 10, 2007 Has anyone tried putting a Swiss Valjoux 7750 into an IWC Portuguese? Even the New Asia version is pretty spotty, so I wondered if anyone tried this route? Link to comment Share on other sites More sharing options...
eunomians Posted May 10, 2007 Report Share Posted May 10, 2007 Not possible. 7750 has running seconds at 9 o'clock. Link to comment Share on other sites More sharing options...
new & improved osteopath Posted May 10, 2007 Report Share Posted May 10, 2007 You can do it, but it requires moving the plate which re-aligns the subdials. This is a risk as the extra plate is made to the same standard as the asian 7750 movement, which seems to be hit or miss. If you have a good watchmaker who will clean up the extra gears this may make it somewhat more reliable. It is a shame, because cosmetically that watch is very spot on. -O Link to comment Share on other sites More sharing options...
RWG Technical Posted May 10, 2007 Report Share Posted May 10, 2007 You could do it, IF you transfered the Asian parts to the Swiss movement... BUT, the problem will remain, to get the running seconds at 6, you need to use all the extra Asian gears, which is where the problem is in the first place. I did a similar transfer with a asian and swiss 7750, with the 7753 subdial layout...have a look here, this is the level of labour required to make this swap. Replacing the Asian 7750 with a Swiss 7750... It can be done, but in the end, the movement will probably not work anyway, due to the extra friction from all these extra gears...
