jmb Posted December 14, 2009 Report Share Posted December 14, 2009 The post about the DSSD case back opener got me up off my butt to try my new adjustable case back opener. I had been wanting to epoxy the He valve closed on this so I figured now was as good a time as any. Even with the "tool" I almost gave up but it finally broke loose. Absolutely dry case back O-ring, not that I was surprised. I pulled the movement and put a couple drops of "5 minute epoxy" down the hole while actuating the valve - shouldn't have to worry about that sucker leaking! It also gave me the opportunity to find a pretty good compromise between the dial and rehaut engraving so really the only "zit" left is the crooked 6:00 marker. Someday I'll try fixing that unless ETZ starts handing out replacement dials. I greased the external tube O-ring, the little O-ring in the crown, and was going to grease the internal tube seal and I did not see one! I couldn't even see a groove for the O-ring. Makes me a bit apprehensive about the water resistance of this build, or did I just get a "boo-boo"? Next time somebody has their crown/stem removed on their V5 take a look and see if you have an O-ring hiding inside the crown tube and let me know...

jmb Posted December 14, 2009 Author Report Share Posted December 14, 2009 I'm almost sorry I did as I'm now pi$$ed about only having two seals... Quote Link to comment Share on other sites More sharing options...
alligoat Posted December 14, 2009 Report Share Posted December 14, 2009 This is why people install gen/aftermarket parts- then you know you have all of the seals. A real 24-7030 case tube has two o-ring seals in it, the crown has one at the base of the stem/crown cap and there is the one on the exterior at the base of the case tube. So it's really a quad lock system! But Rolex never changed the name- the 24-702 crown and tube assembly was the first trip-lock assembly- two in the tube and one on the crown- none at the exterior of the tube. Your deal will probably still work, to 50 or 100m, maybe. Quote Link to comment Share on other sites More sharing options...
panerai153 Posted December 14, 2009 Report Share Posted December 14, 2009 Is the 24-7030 tube and 24-703 Crown the appropriate Crown/tube for the DSSD? If it is, possibly that would be an appropriate "upgrade to insure water tightness, along with epoxying shut the backwards HEV.

gioarmani Posted December 14, 2009 Report Share Posted December 14, 2009 I believe it's flush with the inside of the tube. Here are some old pics of my first V5: Quote Link to comment Share on other sites More sharing options...
jmb Posted December 14, 2009 Author Report Share Posted December 14, 2009 Gio, I will have another look, maybe this weekend, but I didn't see anything... Quote Link to comment Share on other sites More sharing options...
Demsey Posted December 14, 2009 Report Share Posted December 14, 2009 I always figured the seal, internal of the tube, was more a 'dust/moisture as humidity' seal when the crown was unscrewed for settings rather than a 'water' seal. In Gio's pics seal #1 is the frontline for pressure. If water evaded seals 1&2? Water intrusion imminent even if seal #3 was present. As 'alligoat' remarked, you're probably good to go for swimming, bathing etc. Still, it would be preferable to have it J. I would imagine.

Justasgood Posted December 14, 2009 Report Share Posted December 14, 2009 Actually: 1 flat rubber seal where the Tube meets the case. 1 O-ring at the bottom of the threaded portion of the tube 1 O-ring inside the Crown 2 O-rings inside the Tube So it a 5-lock Or Quint-Loc system....doesn't quite roll off the tounge like Trip-loc. Glad to help....hold the applause :-) Quote Link to comment Share on other sites More sharing options...

FxrAndy Posted December 14, 2009 Report Share Posted December 14, 2009 I greased the external tube O-ring, the little O-ring in the crown, and was going to grease the internal tube seal and I did not see one! I couldn't even see a groove for the O-ring. Makes me a bit apprehensive about the water resistance of this build, or did I just get a "boo-boo"? I have and still have watches with only one seal and no screw down crown pass a 10bar test so as long as the seals that you do have are in good order then it should be water tight enough, but if you are going to get it wet then have it tested first Quote Link to comment Share on other sites More sharing options...
jmb Posted December 14, 2009 Author Report Share Posted December 14, 2009 I rarely wear it but I occasionally forget to take off the watch when I get into the shower half asleep so I try to make sure anything I might wear overnight is greased. That's about the only thing I'm worried about... I was just a bit taken aback that this higher-end casework looked to be missing something that even the majority of my cheapie Subs have!
