bones Posted March 31, 2013 Report Share Posted March 31, 2013 Seems this is the stumbling block for a lot of builds. I would love one but finding an aftermarket one seems impossible and gens are just silly. Do we have any solutions to this at all other than patience?

freddy333 Posted March 31, 2013 Report Share Posted March 31, 2013 Never seen a 702 rep. You might want to start saving/searching ebay/tz/vrf, etc for a gen. Link to comment Share on other sites More sharing options...
bones Posted March 31, 2013 Author Report Share Posted March 31, 2013 I had heard rumours that someone known to the board had manufactured some aftermarket 702 tubes. Tubes that is, not the crowns. There's quite a few about it seems. Link to comment Share on other sites More sharing options...

bones Posted April 1, 2013 Author Report Share Posted April 1, 2013 Does the Yuki tube fit a 702 crown? I'll have a look at phong though, thanks. Link to comment Share on other sites More sharing options...
1680 Posted April 1, 2013 Report Share Posted April 1, 2013 Does the Yuki tube fit a 702 crown? I'll have a look at phong though, thanks. No, for a 700 crown you need a 700 tube, for a 702 crown a 702 tube and for a 703 crown a 703 tube. Link to comment Share on other sites More sharing options...
bones Posted April 1, 2013 Author Report Share Posted April 1, 2013 I thought so, just checking. Looks like Phongs 702 crown tube combo is $150. Anyone have experience of his 702 crown?? Link to comment Share on other sites More sharing options...
bones Posted April 2, 2013 Author Report Share Posted April 2, 2013 Hmm, got this response to my questions from Phong 5512 old watch under 2-3 mil can be use 24-700-0 better.with 3 dot crown that good for that no need for 7020 the after market 7020 professional able to tell but if you use 24-7000 is good like factory From my research, it looks like 5512's started in the 3 mil range, 1958 or so. Can't see any evidence for earlier ones. Would they have come with the 700? Also, I think someone on here said the thread for the 700 tube is different to the later versions, so I'm thinking to stick with the 702 since i have all the correct taps for that.

alligoat Posted April 2, 2013 Report Share Posted April 2, 2013 The 5512/3 came out around 1959 with the 1530 movement or the 1560 for the 5512. Those watches used the 700 crown and tube. The crown didn't have the three dots below the crown emblem. The 702 came out in the late 60s and was the first 'triplock' with two gaskets in the tube and one in the crown. The 703 didn't come out until around 1980 or so. It has 4 gaskets, one in the crown, two in the tube and one outside the tube at the base. Link to comment Share on other sites More sharing options...
bones Posted April 2, 2013 Author Report Share Posted April 2, 2013 So for a early 5512 we are looking at a 700 then. Guess that makes sense. Of course accuracy aside there's the issue of actually getting the correct tap for it. Link to comment Share on other sites More sharing options...
alligoat Posted April 2, 2013 Report Share Posted April 2, 2013 I have no idea what the tap size for a 7000 tube is. The 7030 tube takes the 3.0mm x .35 tap. Link to comment Share on other sites More sharing options...
bones Posted April 2, 2013 Author Report Share Posted April 2, 2013 After a bit of back and forth with Phong I've come round to the 700 idea. He's sure the tap size is the same for all the crown tubes which is a worry less. Thanks for everyones advice, I'll post up some pics of the final build.

alligoat Posted April 2, 2013 Report Share Posted April 2, 2013 Since the tap size for the 24-600 crown and tube is the 3mm x .35, it would make sense that all of the other 700 series tubes are the same tap size! The 6mm crown and tube dates back to the 50s at least. Link to comment Share on other sites More sharing options...
marsupilami Posted April 3, 2013 Report Share Posted April 3, 2013 the thread size is the same for all tubes. how many of you want some 702 tubes ? I think about a 2nd batch... let me know. Link to comment Share on other sites More sharing options...
bones Posted April 3, 2013 Author Report Share Posted April 3, 2013 Sure, I'd be interested in a few. Planning some more builds in the future and it would be handy to have some in the parts drawer. Link to comment Share on other sites More sharing options...

phillycheez Posted April 4, 2013 Report Share Posted April 4, 2013 Majority of 5512s and 5513s have a 703 crown these days.. Mostly cause anyone who sent their rolex in to RSC for service had a new crown installed as it was a recommended service. But 702s is where it's at and what I would install. If going gen it's best to find it with the original tube though. Threads can be an issue and you wouldn't want to ruin it. Here's another version of the 702 crown from my old 5513. "hollow holes" Link to comment Share on other sites More sharing options...
freddy333 Posted April 4, 2013 Report Share Posted April 4, 2013 'Hollow holes' result from over-polishing. Link to comment Share on other sites More sharing options...
phillycheez Posted April 4, 2013 Report Share Posted April 4, 2013 'Hollow holes' result from over-polishing.Totally plausible. I just don't think there's enough info out there to make that a conclusive statement. Only reason I'm suspicious is because my 5513 case was barely polished itself which makes no sense why the owner would polish the crap out of just the crown. Of course it's totally possible a previous owner replaced the crown with this one. That's vintage for you and you just never know. Especially cause Rolex never confirms nor denies anything about their vintage models. And the fact that all the info on vintage rolex is practically a bunch of anonymous Internet posters that collaborated their knowledge and information on some site... Excluding a very small handful of published and known Rolex enthusiasts. http://www.network54.com/Forum/207593/thread/1298566375/Submariner+168000+Crown+questionhttps://www.rolexforums.com/archive/index.php/t-165045.html Link to comment Share on other sites More sharing options...
freddy333 Posted April 4, 2013 Report Share Posted April 4, 2013 Remember, these are wrapped crowns (I have never seen this on a 704). That is, a thin sheet of steel is wrapped over a metal substrate. Over time & after successive polishings, the wrapping gets worn away at the highest points, leaving holes.

phillycheez Posted April 4, 2013 Report Share Posted April 4, 2013 True. And if i were to put my money on it I would say it's due to polishing or weathering to some extent. If anyone wants to try over polishing their 702 crown to see if they can replicate the hollow holes... I'll try it if I come around to owning one again. I think it's a cool characteristic.
