jmb Posted October 29, 2009 Report Share Posted October 29, 2009 I'm putting together a "tooling" order as I need some stuff for my shop and figured I'd order some taps and what have you for the tube and crown on Rolex (Subs and what have you). I seem to remember the tube as a 3mm but can't remember the pitch or what the crown is. Thanks... Link to comment Share on other sites More sharing options...
alligoat Posted October 29, 2009 Report Share Posted October 29, 2009 Tapping the hole in the case takes a 3.0mm x .35 tap. On MBW's it might be a good idea to drill out the case hole w/ a 2.65mm drill bit, then tap. Crown is the 7mm, 24-703-0, tube is the 24-7030-0, the last 0 denotes ss. Might not be a bad idea to pick up the little wrench tool for installing the case tubes- Ofrei and Jules Borel have them. Taps can be bought for less if you look on line- do a search. Maybe $6 ea plus s&h- beats Ofrei and JBorel! Easy to buy a couple at that price. I've beem doing well recently with the aftermarket casetubes that Mr. Slimeball sells (wholesaleoutlet990). Jewelerstools sells used 24-703 crowns- cheaper the more you buy. Used to be able to buy them for $20 or so on the bay, now maybe $35. I still haven't the guy over in HK w/ the $14+ crown and casetube- it would be nice if those are decent copies! Link to comment Share on other sites More sharing options...
jmb Posted October 29, 2009 Author Report Share Posted October 29, 2009 goat, I've bought several 6mm and 7mm crowns from the "hong-kong" guy and they seem to work out OK. Comparing one of his right next to a gen you can see differences but they are still better than what I'm replacing. I have bought from him off the 'bay and he'll usually give a shipping discount. Here's my Noob with one of his crowns: Link to comment Share on other sites More sharing options...
alligoat Posted October 29, 2009 Report Share Posted October 29, 2009 Yeh, I just need to buy a set of those just to check them out. With the modern noobs, MBK/Euromariners and WM9's using decent copies of the gen, they've got to be available. Link to comment Share on other sites More sharing options...
jmb Posted October 29, 2009 Author Report Share Posted October 29, 2009 The one in the picture is from that parts4rolex guy... The one that was on my Noob when I got it was huge! Link to comment Share on other sites More sharing options...
preacher62 Posted October 31, 2009 Report Share Posted October 31, 2009 (edited) This is my Noobmariner with BK's custom crown set. Fat tube. Crown isn't perfect but better than Noob crown. And it screws into the same Noob case tube drilling. Edited October 31, 2009 by preacher62 Link to comment Share on other sites More sharing options...
jmb Posted October 31, 2009 Author Report Share Posted October 31, 2009 parts4rolex guarantees this crown/tube set to be interchangeable with the gen Rolex parts and I found that it also screwed into the Noobmariner case just fine. Link to comment Share on other sites More sharing options...
preacher62 Posted October 31, 2009 Report Share Posted October 31, 2009 That's great to know...thanks for info, jmb! Always lookin for parts that work without too much milling. Most of us don't have a machine shop. I am really interested in your lug hole drilling. Let me know if you want to do some. I have an MBK case coming to put that Noob in. I saw one that have been drilled...2mm just like gen. Looked awsome. MT Link to comment Share on other sites More sharing options...
jmb Posted October 31, 2009 Author Report Share Posted October 31, 2009 Thanks, preacher. I think right now I wouldn't be nervous about opening up existing lug holes for somebody other than myself but I still want to get a bit more practice drilling them "from scratch".

preacher62 Posted November 1, 2009 Report Share Posted November 1, 2009 I understand that. I would appreciate it if you would just update us on how your setup is coming. I have thought about building a wooden jig. Cut it out to fit the case perfectly. Locate the drilling and install a steel tube through the jig where the drilling would be. To stabalize the bit. Then I read, with interest your article on the use of a set and a center bit before actually drilling the final. Makes perfect sense that drilling into a piece of SS, at an angle, the bit will walk. Just glad I read your article before I screwed something up. That's what this board is for. MT Link to comment Share on other sites More sharing options...
jmb Posted November 1, 2009 Author Report Share Posted November 1, 2009 A complete drilling jig would be really nice if the holes could be trusted to always be in the same spot. Unfortunately I don't have that much trust in Chinese manufacturing and tolerances... Link to comment Share on other sites More sharing options...

I just received an MBK case set from ET and one of the things I want to do is change the crown to gen-spec tube and crown. Thanks! Link to comment Share on other sites More sharing options...
alligoat Posted November 18, 2009 Report Share Posted November 18, 2009 Preacher, whenever you change out a case tube, it's a good idea to run the 3.0mm x .35 tap thru there- to clean out the glue and just to make sure the threads are correct for the rolex (or aftermarket) case tube. I broke a tap in an older MBK case over a year ago and some of the older MBK cases have smaller than gen holes. If you can run the tap thru w/o too much resistance, you're probably OK. If you are forcing it, it's time to back out the tap and run the 2.65mm drill bit thru there and then tap the hole. On my Euro 16610(MBK) case, all I had to do was tap it, but I believe the crown and tube were the latest batch which are a copy of the Rolex gen. So if you have en older MBK case you might want to be aware of this so you don't break the tap like I did. Link to comment Share on other sites More sharing options...
preacher62 Posted November 18, 2009 Report Share Posted November 18, 2009 Thank you much! I just received the case (MBK 16610) from Eurotimez on yesterday. I believe it to be new. It is not the M Series. Additionally, it does not have a gen-like crown. If it did I would probably leave it along. The crown is more Noob-like only not quite as thick. Great info, though. Better than tearing up my new case. No matter how good the case is...if you are not good at adaptation you'll pull your hair out. Thanks again. If you have more info from this, please share.

alligoat Posted November 18, 2009 Report Share Posted November 18, 2009 One quick thing. W/ the new cases, new crown and tube, you may be able to install a gen crown w/o removing the tube- the gen crown may screw down on the rep tube- I remember a few people doing that. I removed the tube to file down the cg's and trashed it out removing it, so I went back w/ an aftermarket tube. Ironically I like the wholesaleoutlet990 tube better than the Clarks Watch Supply one- but both are soft- I've snapped off three or four now! That's why you need to tap the hole all the way, go slowly and be careful. Also might need to countersink the hole w/ a larger drill bit to seat the tube all the way in the case- just don't countersink too much- it will wallow out the sides of the case.

preacher62 Posted November 18, 2009 Report Share Posted November 18, 2009 Thanks, again! I was hoping that that was the case. I'll try. On my Noobmariner it was great to get BKs case set as it just screwed in the current drilling. I'll try a crown from wholesaleoutlett999. I have bought items from them before. You're always very helpful and we appreciate it. MT Link to comment Share on other sites More sharing options...

MT Sorry to necropost here...but since the cartels (trusty & pt) are offering their 1680s this year, with 2846 movement...what is the current experience with the crowns/case tubes in these new 1680 versions? Also, is wholesale still making a decent case tube? what about yuki or clark? And how come I never see a 7mm case tube tool listed anywhere....or is the 6mm case tube tool used for the 703 case tube as well? thanks for the input in advance Link to comment Share on other sites More sharing options...

redwatch Posted August 7, 2010 Report Share Posted August 7, 2010 Sorry if this seems like a dumb question, but I've been searching McMaster-Carr, MSC, Grainger, Ofrei and others for this tap and I just can't find it. Is the posting correct? 3.0mm x 0.35 tap? I searched for that as well as an M3 x 0.35 Tap. Each search came back with a 3.0 x 0.5 Tap or M3 x 0.5 Tap. Am I missing something here?
