Rolexman Posted November 24, 2007 Report Share Posted November 24, 2007 (edited) Tried the search function but without any results. There's no screw in the middle, only three holes. Do I need a special tool for it? Edited November 24, 2007 by Rolexman Quote Link to comment Share on other sites More sharing options...
FxrAndy Posted November 24, 2007 Report Share Posted November 24, 2007 You have a shiny ring with 4 cutouts on it, on the inside of this ring you have flats that when aligned with the flats on the bearing will allow the rotor to be removed, i had a small problem with my AT with the seagull where the retaining ring turned its self and the rotor fell off !, i got it back on no problems with a couple of screw drivers, i am sure that there is a special tool with 4 prongs to do this a lot easyer.

docblackrock Posted November 24, 2007 Report Share Posted November 24, 2007 Those three holes do contain three screws, except they are inverted. In terms of assembly, the rotor is actually a more attached part of the auto-winding mechanism than say the rotor on a 2836 or 7750. See pics.... And in situ... So you'll need to disassemble more than you're used to. What are you trying to do anyway? Rotor swap for logo? Quote Link to comment Share on other sites More sharing options...
FxrAndy Posted November 24, 2007 Report Share Posted November 24, 2007 That is a different one DBR, my seagul one looks like this 2892 here below Quote Link to comment Share on other sites More sharing options...

docblackrock Posted November 24, 2007 Report Share Posted November 24, 2007 That is a different one DBR, my seagul one looks like this 2892 here below If it's Seagul then it's a clone. Rolexman is talking about a standard ETA 2892. Quote Link to comment Share on other sites More sharing options...

FxrAndy Posted November 24, 2007 Report Share Posted November 24, 2007 @ DBR i cant find a picture of another 2892 with a rotor like the one you show?? Quote Link to comment Share on other sites More sharing options...
RWG Technical Posted November 24, 2007 Report Share Posted November 24, 2007 @ Doc I have never seen your style of Rotor attachment, it must be an aftermarket non-ETA one...looks as if it only comes apart from below. RG Quote Link to comment Share on other sites More sharing options...
FxrAndy Posted November 24, 2007 Report Share Posted November 24, 2007 @Z do you have special tool to remove the rotor or just use a screw driver to rotate it, i know you can get them off very well that way but getting them on is a pain as you have to put pressure downwards and rotate at the same time.

I use a grey screwdriver to rotate the spring. For installation I use my finger to get the 4 corners to engage into the bearing, then turn it. Once done I clean it off with Rodico...works fine, as long as your careful. RG Quote Link to comment Share on other sites More sharing options...

Rolexman Posted November 24, 2007 Author Report Share Posted November 24, 2007 (edited) Thanks for all the info guys! I was referring to the Valgranges copy movement in the Chopard GTXL. I thought all the three rotor attachment systems were the same. Apperently I was wrong, sorry. This is the movement and rotor I'm talking about: Do I just unscrew the three tiny screws?

FxrAndy Posted November 25, 2007 Report Share Posted November 25, 2007 That is where i would start but never done it my self Quote Link to comment Share on other sites More sharing options...
olivia Posted November 25, 2007 Report Share Posted November 25, 2007 Yes...remove the three screws. That worked for me just fine. I could not see any other way of removing it. Quote Link to comment Share on other sites More sharing options...
docblackrock Posted November 25, 2007 Report Share Posted November 25, 2007 Do I just unscrew the three tiny screws?Call me pedantic but I'd start with those eight tiny screws on the caseback first Quote Link to comment Share on other sites More sharing options...
offshore Posted November 25, 2007 Report Share Posted November 25, 2007 Call me pedantic but I'd start with those eight tiny screws on the caseback first Hmmm, maybe not too pedantic doc! He could alternatively start by using one of these! Offshore Quote Link to comment Share on other sites More sharing options...

SSTEEL Posted April 28, 2014 Report Share Posted April 28, 2014 You have come a long way mate I need one of these tools, and for what it is, and does, its damn expensive for what it is, so looked for an alternative, and found a clone of one for €55 euros delivered Quote Link to comment Share on other sites More sharing options...
