phwtan Posted May 10, 2015 Report Share Posted May 10, 2015 Looking to add another mod to my current TC based frankensub. Following are the gen components so far: 93250 bracelet bezel insert crystal (with LEC) bezel click spring Looking to add a gen crown. Are both gen 703 and 704 crowns compatible? Is a gen tube essential? Where is the best source for a reasonably priced crown? I've seen someone suggest that it's possible to get gen crowns for USD$50...is this true? Thanks!

marrickvilleboy Posted May 10, 2015 Report Share Posted May 10, 2015 703 will fit for sure. I thought the 704 had different threads to the 703 tube - someone to confirm. You can get USED 703s for around $60-80 Quote Link to comment Share on other sites More sharing options...
phwtan Posted May 10, 2015 Author Report Share Posted May 10, 2015 Thanks! Where's the best place to source used ones? eBay and VRM tend to have brand new ones for about $USD120+ Quote Link to comment Share on other sites More sharing options...

watcher Posted May 11, 2015 Report Share Posted May 11, 2015 Same threads. Rolex only make one 703 crown tube. 703 is correct for a tc but I had a 704 on mine. Depends if you're that bothered. I had standard tc tube. Quote Link to comment Share on other sites More sharing options...
dbane883 Posted May 11, 2015 Report Share Posted May 11, 2015 Yeah.. 703 tube is correct for both the 703 and 704 crowns Quote Link to comment Share on other sites More sharing options...
J.S. Posted May 11, 2015 Report Share Posted May 11, 2015 (edited) 703 is older generation crown (5 digits) like 16610 704 is newer generation crown (6 digits) like 116610 704 is "monobloc" and my conclusion is it's better because it's crafted from single block not capped like 703.
