Ronin Posted February 3, 2011 Author Report Share Posted February 3, 2011 Cool. Thanks. Where did you find the Crystal info. Is there a "Reference Guide" out there somewhere? I thought the dial size may be more in line with a Sub or SD, but could be wrong. Probably in the 26.5 range??? 1675 are 27.3... Do ALL GMTs use 5.3mm? TIA.

grifter Posted February 3, 2011 Report Share Posted February 3, 2011 (edited) i thought the fat lady used sapphire crystals.. the 116 is for 1675. also read that the fat lady dial is same diameter as the 16710 T dials. (what that diameter is... dunno ) Edited February 3, 2011 by grifter Quote Link to comment Share on other sites More sharing options...
Mapman57 Posted February 3, 2011 Report Share Posted February 3, 2011 i thought the fat lady used sapphire crystals.. the 116 is for 1675. That is correct M - the 16760 Fat Lady has a sapphire crystal ........and a 78350/501 bracelet assembly. Some newer models have the 78790A/SEL bracelet set up. Really nice model......retaining the drilled lugs, kind of transitional Quote Link to comment Share on other sites More sharing options...
JoeyB Posted February 3, 2011 Report Share Posted February 3, 2011 Yep, my bad. The 16760 introduced the sapphire crystal. Quote Link to comment Share on other sites More sharing options...

chefcook Posted February 3, 2011 Report Share Posted February 3, 2011 Hand Stack: Hour - GMT - Minute - Second Sorry, a lot of misinformation here regarding the part numbers. According to Rolex Part catalog R20 from 2003: Crown: 24-603-0 6mm!!!! Tube: 24-5330-0 same as for 5.3mm crowns Spring bars: 23-12200 (same as Sub 16800 or 16610 with lugholes, NOT the same as 16610T). Crystal gasket: 29-295-2 (same as 16800 / 16610 / 16710) Crystal: 25-295-C2 (same as 16800 / 16610 / 16710) Bracelet: 78360 Endlinks: 501 There never was a 16760 with SELs as the 16760 went out of production long before SELs were introduced. The 16760 was only available with the Coke insert. The dial is the same as used in early 16710, so only glossy with white gold indices and tritium. Dials are interchangeable between 16760 and 16710. All 16760 were marked SWISS-T < 25 The caseback is different from the 16710, it looks more similar to a submariner case back but it has a different part number. I would not go the 16760 route as there is no accurate case. The 16760 really deserves her nickname! The case is much thicker than a 16710, it is comparable in thickness to a Sea Dweller 16600. Even the crown guards are much thicker than on the 16710. So, if you have the parts for a 16760 - make an early 16710 from it Quote Link to comment Share on other sites More sharing options...
Ronin Posted February 4, 2011 Author Report Share Posted February 4, 2011 GREAT INFO! I had a gut feeling the crown was 6.00 Actually... I think I have a case lined up, and am working OUTWARDS from the case. Thus the dial/crystal questions.... So I can use a 16760 OR 16710 dial... Still looking for actual diameter of dial.... ??? The case I might be getting is an aftermarket 16600 minus the HEV... Like to pre-plan and make sure dimensions are correct before dial/movement investment. It will be a total one off if I pull it off... Quote Link to comment Share on other sites More sharing options...
