milesd Posted May 29, 2011 Report Share Posted May 29, 2011 So I'm building a 5517 and I wanted a specific gen crown (I eventually found out it was a 702). At first, not knowing much about Rolex, I bought the first gen crown and tube I saw posted on the forum. However after doing much research I found the crown I wanted was a 24-702. During the hunt, I ended up with a 24-703 (with long logo) and a modern crown. However this weekend I finally found a 24-702 and I've got an aftermarket crown tube from a member here. Thanks to RWG members as I did a search and found all the info I needed here. 702 - 703 - 704?? 702 vs 703 702 tube vs modern tube Link to comment Share on other sites More sharing options...
Nanuq Posted May 30, 2011 Report Share Posted May 30, 2011 IMHO, the 702 is the king of Rolex 7mm crowns. Nicely done! Link to comment Share on other sites More sharing options...
alligoat Posted May 30, 2011 Report Share Posted May 30, 2011 Nice comparison. The thread pitch on the case ends of the 702 and 703 tubes looks slightly different... You would hope the 702 tube is 3.0mm x .35 just like the 703 tube. I have a 702 case tube which came out of my '78 1680, I'll look at it tonight when I get home. I had to go to the 703 assembly a few years ago when my crown putzed out- threads stripped out in the stem end. Since then, I've picked up a 702 crown in case I decide to switch back.

Yes, I noticed that. I hope everything fits with my mbw case. Link to comment Share on other sites More sharing options...

Mapman57 Posted May 30, 2011 Report Share Posted May 30, 2011 Wow, great picture set as well. Helps us more noob like members, to really see the difference between the evolution of the respective gen crown models. Good luck with that 5517 build, looking forward to the 'regular updates here' Link to comment Share on other sites More sharing options...

Dizzy Posted June 6, 2011 Report Share Posted June 6, 2011 So I need a different tap if im going to change to a 702 tube? The threads look completely different. Link to comment Share on other sites More sharing options...
Ephry73 Posted September 15, 2011 Report Share Posted September 15, 2011 So what is the consensus when using the 702 tube? different tap size/pitch? E Link to comment Share on other sites More sharing options...
krpster Posted September 15, 2011 Report Share Posted September 15, 2011 IMHO, the 702 is the king of Rolex 7mm crowns. Nicely done! Hey Nanuq, what about it makes you feel that way? Just curious Link to comment Share on other sites More sharing options...
ubiquitous Posted September 15, 2011 Report Share Posted September 15, 2011 Have to agree... 702 is my favorite as well... Link to comment Share on other sites More sharing options...
Nanuq Posted September 15, 2011 Report Share Posted September 15, 2011 Hey Nanuq, what about it makes you feel that way? Just curious I like several things about the 702. Mostly I like the beveled back and how it looks in between an old pair of crown guards. That little gap to the case is essential for vintage Rolex. Then I like the fully exposed threads. With a 703 part of the threads are covered by the crown and if you get crud in there (inevitable) it can't be cleaned out and the crown/tube threads can get stripped. Finally, you can clean/wax the threads on a 702 tube with a piece of dental floss and keep 'em smooth as a baby's butt. Nothing finer. Link to comment Share on other sites More sharing options...

If Yuki has the 702, it will be good to know for sure. Ordering my 702 tube later tonight from marsupilami Link to comment Share on other sites More sharing options...
woof* Posted September 15, 2011 Report Share Posted September 15, 2011 702= twinlock ephry? Link to comment Share on other sites More sharing options...
ubiquitous Posted September 15, 2011 Report Share Posted September 15, 2011 702 is technically a Triplock. 700 is a Twinlock... Link to comment Share on other sites More sharing options...
Ephry73 Posted September 15, 2011 Report Share Posted September 15, 2011 I'm sure the twinlock tube could be used, but I am not sure how water tight the seal will be. I guess if there was enough "crush" on the rubber o-ring with the top of the twin-lock it would be ok, but looking at the designs of the two tubes, there is a gap that's too large to just simply squeeze harder. The tubes that Yuki sells are for the "dot-less" 700 crowns I believe. E Link to comment Share on other sites More sharing options...
woof* Posted September 15, 2011 Report Share Posted September 15, 2011 I didn't know that, I thought the reason at service.. they went from the 702 to the 703, was newer better (from twin to triple) technology. Link to comment Share on other sites More sharing options...
