the collector Posted April 24, 2006 Report Share Posted April 24, 2006 I want to fit a genuine Rolex crown to a 6263 case, i have been doing some research and now i am a bit confused about the reference number of the Rolex crowns. Please help me to finally clarify what refernce the correct crown for a 6263 has.... Thanks Link to comment Share on other sites More sharing options...
the collector Posted April 24, 2006 Author Report Share Posted April 24, 2006 @nanuq as far as i know the original 6263 used to acrry a twinlock crown and as these crowns where worn out they would be replaced with the newer triplock crown.... but the question is which triplock?

leitztozeiss Posted April 24, 2006 Report Share Posted April 24, 2006 (edited) Triple lock crown, 7mm tube. Part numbers are: Crown: 24-703 Case Tube: 24-7030 This is according to info obtained from a search a TRC - CLICK HERE to read. I hope this helps. I'd like to install a gen on my 6263 also.

ubiquitous Posted April 24, 2006 Report Share Posted April 24, 2006 The 6263/5's all had Triplocks- The Cosmographs with Oyster signed dials were outfitted with Triplocks from the start, not Twinlocks. Twinlockers were the 6239/6240, etc with non-Oyster signed dials. As such, any Triplock 7mm crown is sufficient for a 6263/5, as it is likely these have been replaced during a service with the most recent variation. 24-703 should work nicely.

Guest avitt Posted April 25, 2006 Report Share Posted April 25, 2006 I think that this is germane...Here is a comparison between two of the aftermarket Triplock tubes. On the left is the version from Cousins (Clockspares.com), and on the right is the Helfands version (please excuse the dried lock-tight). I can't comment on the quality, other than to say that I've already torqued the threads off one of the Helfands...my fault entirely. Link to comment Share on other sites More sharing options...
pitimany Posted April 25, 2006 Report Share Posted April 25, 2006 Do anybody know a US source for Triplock tubes (Clockspares is Uk), please PM me ? I tryed Helfands, way too short. they can be secure more adding glue, but no my choise. Link to comment Share on other sites More sharing options...

(However, I'm open to alternate source as well). Link to comment Share on other sites More sharing options...
Sherrington Posted April 25, 2006 Report Share Posted April 25, 2006 The pre-Daytonas came with Twinlock crowns and pump pushers... here's a good photo: Hey Bob. That's in mint condition for one of your watches. Have you not aged it yet? Link to comment Share on other sites More sharing options...
the collector Posted April 25, 2006 Author Report Share Posted April 25, 2006 @Avitt, that looks like a damn nice tube.... good price aswell.... thanks for the info Link to comment Share on other sites More sharing options...
Guest avitt Posted April 26, 2006 Report Share Posted April 26, 2006 @collector, thought you might want to see how that tube looks on a Daytona case: Link to comment Share on other sites More sharing options...
the collector Posted April 26, 2006 Author Report Share Posted April 26, 2006 @Avitt. nice... thanks alot. BTW is that a gen case or a aftermarket? Do you by any chance know if the 6263s carrry gaskets for the crystal? I want to make mine waterproof so i do not have to take it off when i go for a swim....

Guest avitt Posted April 26, 2006 Report Share Posted April 26, 2006 That case is an aftermarket. It's my understanding that vintage Daytona's don't use gaskets around the crystal. You could probably use one...I'd suggest a flat gasket, with in internal diameter of about 29.5mm. I'm not sure what this would do to the watch's profile. Another suggestion (which comes from Nanuq) would be to spread a little silicone grease around the lip of the case, before fitting the crystal.

pitimany Posted April 26, 2006 Report Share Posted April 26, 2006 (edited) Fully aggre with Nanuq I have try to make and test my DW water proof, and only made about 0.1 atm (1.3 meter ) during water test, a tiny bubble started to form next to upper pusher. This make my watch water proof, but no water resistant P Correct, most vintage don't have a gasket there, like the sapphire crystals use. It's a raised lip over which the crystal fits, then the retaining ring squeezes the crystal down onto the lip. A little grease in the two interfaces helps. The exception to this rule is the 1665 Sea-dweller. Beneath the crystal retaining ring there is a machined groove into which an o-ring fits. The ring presses down on the o-ring and "inward" against the crystal. If it were up to me, I wouldn't take a chrono in the water. Just too many places for it to leak, "Oyster" designated or not. I save the swimming for my dive watches. Edited April 26, 2006 by pitimany Link to comment Share on other sites More sharing options...
the collector Posted April 27, 2006 Author Report Share Posted April 27, 2006 (edited) Nanuq you are quite right, better to use the right watch for the right purpose.... @Avitt, that is a beautiful case.... is that a gen tube that is fitted or the cousins tube? BTW has anyone seen any heavy 78350 for 6263 for sale? Edited April 27, 2006 by the collector Link to comment Share on other sites More sharing options...
Guest avitt Posted April 27, 2006 Report Share Posted April 27, 2006 Thanks collector. That's the Cousins tube. I'm impressed with the quality. BTW, theres no need for a special tool to install this tube...a T8 Torx bit does the job perfectly. Link to comment Share on other sites More sharing options...
the collector Posted April 27, 2006 Author Report Share Posted April 27, 2006 I want to get hold of a nice steel bezel for my other project.... do you guys know where i could get hold of a good one. I have been looking around a bit and noticed that usually the numbers on the steel bezels are too bold.... How are DW´s steel bezels? Link to comment Share on other sites More sharing options...
Guest avitt Posted April 27, 2006 Report Share Posted April 27, 2006 Unfortunately, the DW 200 Units/Hr steel bezel is discontinued, due to lack of demand....(I know, I thought the same thing...) Link to comment Share on other sites More sharing options...

halley Posted April 28, 2006 Report Share Posted April 28, 2006 Thanks collector. That's the Cousins tube. I'm impressed with the quality. BTW, theres no need for a special tool to install this tube...a T8 Torx bit does the job perfectly. I have what appears to be helfand tube and the T8 Torx does not work, even a T10 is too small for the inner tube, so I'm off buying the real tool!

the collector Posted April 28, 2006 Author Report Share Posted April 28, 2006 @halley what tube are you inserting, genuine or aftermarket? Link to comment Share on other sites More sharing options...
Guest avitt Posted April 29, 2006 Report Share Posted April 29, 2006 @Halley, it's never a bad idea to get the right tool for the job...But I should have given you a bit more information. Here is a picture of the bits that I use. A Mibro Torx T9 insert bit is perfect for the helfands tube, while a T8 is the one for the Cousins tube (hmm...I guess the Cousins has longer threads AND a thicker wall). It's really the shoulder of the bits that snug onto the tubes. The teeth do pass through, like you've mentioned. Here's an end shot: These really work well for me. And holding the bits by hand helps to ensure that I don't overtorque anything. Link to comment Share on other sites More sharing options...
