FasTTaP Posted July 12, 2007 Report Share Posted July 12, 2007 Hi, I've got this 7750 pre daytona, the gen is supposed to host a Valjoux cal. 72 and I could'nt find the following info : is this an automatic or a manual movement??? Gen info link (first watch on the list) rep: gen: This watch has to go to an extensive vintaging process before even considering wearing it, and I guess servicing the 7750 will have to be done, so should I have the rotor disable (it the valjoux 72 happens to be a manual winding watch) ???

Guest RiverwindMDS Posted July 12, 2007 Report Share Posted July 12, 2007 The valjoux 72 is handwind... Link to comment Share on other sites More sharing options...
FasTTaP Posted July 12, 2007 Author Report Share Posted July 12, 2007 Arg... I was affraid of that... So should I disable the 7750's rotor to get close to the gen ??? Link to comment Share on other sites More sharing options...
Guest RiverwindMDS Posted July 12, 2007 Report Share Posted July 12, 2007 Arg... I was affraid of that... So should I disable the 7750's rotor to get close to the gen ??? Just take it off... But the subdial spacing is very different from the two movements... Link to comment Share on other sites More sharing options...
RWG Technical Posted July 12, 2007 Report Share Posted July 12, 2007 Arg... I was affraid of that... So should I disable the 7750's rotor to get close to the gen ??? What purpose would it serve to remove the rotor? You can't see it, and if the rotor is in place, the watch will wind as you wear it. If you wanted to remove the rotor, you left with hand winding it all the time, and I am not sure what that will prove? RG Link to comment Share on other sites More sharing options...
FasTTaP Posted July 12, 2007 Author Report Share Posted July 12, 2007 Well, if the rotor was removed, the watch woul'nd make any noise, witch would be a quick giveaway to any expert Link to comment Share on other sites More sharing options...
eunomians Posted July 12, 2007 Report Share Posted July 12, 2007 Well, the dead giveaway (rotor or rotor removed) would be the huge caseback to fit the 7750, and the seriously flawed subdial placements. Also, no Tritium dots and rhodium plated markers/hands would also tell any Rolex WIS that it is a fake. The 7750 is a thick 7.9mm movement since it consists of 3 layers (mainplate, day/date plate and chronograph plate). The gorgoeus Valjoux 72 is manual wind with no day/date function, thus it is much much thinner than the 7750. And since it is a column wheel chrono, it is much more expensive due to the vast array of refined parts needed when compared to the inexpensive 'heart piece' coulisse-lever design of the 7750.

HauteHippie Posted July 12, 2007 Report Share Posted July 12, 2007 Well, if the rotor was removed, the watch woul'nd make any noise, witch would be a quick giveaway to any expert The watch isn't very convincing with the rotor removed, so why bother? My recommendation is to just enjoy the watch instead of trying to trick people with it. Link to comment Share on other sites More sharing options...

Jimster Posted July 14, 2007 Report Share Posted July 14, 2007 Rob, I'm in need of a sweep hand to fit my DW 6263 VJ 724. Do you by chance have any? Please let me know. Best regards, Jim seaop@aol.com Link to comment Share on other sites More sharing options...
