milsub5517 Posted November 15, 2008 Report Share Posted November 15, 2008 sorry guys i know im late , but whats the overall opinion on these new movements with seconds at 12 in AP's? EDIT: found a link to a tear down review on rep geek: http://www.repgeek.com/showthread.php?t=25910 looks like not all extra gears have jewels... Mike's conclusion: So what is my conclusion? First off, the modification is not badly thought out and the idea of transferring via a gear running coaxially with the cannon pinion is quite smart, it adds sturdiness to the entire mechanism. All of the jewels are quite flimsy except for the one which the running seconds gear rotates in, and there are no jewels in the bottom plate at all. Using graphite lubrication will certainly help, but I have several Daytonas and Portugueses with running seconds at 6 and have never had any serious probems even with the unlubricated ones. Perhaps I've just been lucky! Datewheel swaps and painting in the area around the date window will be tricky since it requires removing several plates of the modification module. Removing the dial is more difficult than usual due to the dial feet extending through the entire module (and the common problem with crappy dial feet clamps on A7750's). Further and more intelligent conclusions will have to be drawn by people much more knowledgeable than me! I hope you feel that reading this post wasn't a waste of time. Mike.

Mike's conclusion: You have in this forum a very detailed analysis of the movement of this watch: http://www.rwg.cc/members/index.php?showtopic=78001 Francisco.

milsub5517 Posted November 15, 2008 Author Report Share Posted November 15, 2008 thank you Francisco! So the movement is still problematic wih some gears running over the surface. God, it takes them forever to design good transfer plate.. is running secs at 9 version mechanically better? Quote Link to comment Share on other sites More sharing options...
