denimhead Posted March 4, 2014 Report Share Posted March 4, 2014 Calling all Movement experts, I'm assuming not, but in theory would an eta 7750 rotor fit the eta 2892-A2 movement? Was there ever a Gen eta modified chrono version of the 2892-A2 Cheers Quote Link to comment Share on other sites More sharing options...
jpz5142 Posted March 4, 2014 Report Share Posted March 4, 2014 I'm by no means a movement expert but yes there was a Chrono module for the 2892. AFAIK it was just that, a module that was added on top of an existing 2892 base movement. As far as the rotor, don't think they're compatible tried looking at part numbers to prove my point but got crossed eyed.... maybe someone with more authority can come along with the part numbers for you.

kbh Posted March 4, 2014 Report Share Posted March 4, 2014 Interesting thing about the 2892-2; it was purposely made thin so it could be used as a "tractor" for other modules, including GMT, chrono, moon phase and others. And the rotor attachment is totally different. Quote Link to comment Share on other sites More sharing options...
krpster Posted March 5, 2014 Report Share Posted March 5, 2014 To answer your two questions seperately... Structure of the oscillating weight between these two movements is completely different. Not compatible in any way. As kbh has mentioned the 2892 is used to power many complication modules. As an example a common unit used by Tudor and Hublot is the Dubois Depraz chrono module.

Guest Posted March 5, 2014 Report Share Posted March 5, 2014 The two rotors are very different. 7750 is pretty large compared to the 2892. Also, the 2892 rotor requires a more sophisticated process to be removed compared to the one screw of the 7750 Sent from my SAMSUNG-SGH-I747 using Tapatalk 2 Quote Link to comment Share on other sites More sharing options...
