mucrewbtp Posted January 18, 2008 Report Share Posted January 18, 2008 I already posted this on repgeek, and some members over there suggested that I post it here to see if any of the rolex experts might know the answer. I have a MBW 1665 DRSD on order and I would like to do some mods. I found a clark T39 superdome and a source for a bezel insert. I also found several 7MM triplock sub crowns. By looking at the crown is there any way to tell if it takes the new style or old style tube? Also has there been any major change with the crowns, or could I put a new style crown and tube on the vintage 1665? Thanks, Mike Link to comment Share on other sites More sharing options...
freddy333 Posted January 18, 2008 Report Share Posted January 18, 2008 I do not know alot about these, but Rolex service will replace whatever is currently on a gen 1665 with a 703 Triplock. I believe the main differences between the 700, 701, 702 & current model 703 are the dots (and their location) below the crown & circumference of the inner shaft which the stem screws into. The 703 has 3 dots located relatively close to the crown, while earlier versions had either no dots (just the crown) or the dots were further away from the crown (closer to the edge of the crown). I believe the current 703 also has a thicker shaft than earlier versions, which requires a larger opening in the tube as well as a different location for the splines that mate with the Rolex tube tool. I have a spec sheet that describes the differences, but I cannot locate it right now. But this may be helpful (steel/yellow gold, white gold & platinum) Link to comment Share on other sites More sharing options...
alligoat Posted January 18, 2008 Report Share Posted January 18, 2008 As freddy says, the current 7mm crown for a Rolex sub- or SD for that matter. is the 24-703-0. The tube is PN 24-7030-0. The last 0 denotes SS. Earlier crowns, 700, 701 and 702 are not compatible w/ the 703, or the 703 tube. When Rolex services a DRSD (if they still would), they would undoubtably install a 24-703 crown and tube assembly. Older style tubes are about impossible to come by these days. Here's a Rolex crown from Mark Greenberg- moelarrycu in NYC http://cgi.ebay.com/SS-Rolex-Submariner-Se...1QQcmdZViewItem item # 22019253564 on ebay. Pricey, no doubt. He also has gen case tubes for around $46 or so. These from suissetime may or may not be 24-703-0 crowns- you have to ask: http://cgi.ebay.com/ROLEX-SUBMARINER-CROWN...1QQcmdZViewItem item # 230212466772 if the link doesn't work Here's an aftermarket tube from Clark's- these work, but are delicate- first you have to retap the case tube hole all the way, maybe countersink the case and finally install the tube carefully so as not to snap it off. Tools from ofrei will run close to $100 to do it correctly http://cgi.ebay.com/Case-tube-Ref-24-7030-...1QQcmdZViewItem item # 300165713453 if the link doesn't work. Putting a gen crown and tube (or aftermarket tube) in isn't cheap and it's not a task for the novice, but it improves the looks and function of the watch immensely.

mucrewbtp Posted January 19, 2008 Author Report Share Posted January 19, 2008 Thank you for the help so far, Since RSC will put the curent crown on when serviced, I will just buy the crowns I have found and install them. I hope the seller knows what style of crown tube his crowns require. Thank You, Mike As freddy says, the current 7mm crown for a Rolex sub- or SD for that matter. is the 24-703-0.
