marcoxxx1984 Posted August 28, 2011 Report Share Posted August 28, 2011 Hi I need your opinion about my project for a nice modern daytona: - daytona steel black dial without rehaut engravings 21j - frozen the central second hand and leave only the one at 6. Ok I will not have chrono but who cares??? - Clark tropic - ofrei pushers - gen crown/tube + cg mods Thanks Quote Link to comment Share on other sites More sharing options...
dutchguy2 Posted August 28, 2011 Report Share Posted August 28, 2011 It looks like that you are mixing vintage stuff with modern stuff. I don't think that that will work! Quote Link to comment Share on other sites More sharing options...
praetor Posted August 28, 2011 Report Share Posted August 28, 2011 There's some problems with your plan. First of all, tropic crystals are plastic crystals, which has a different crystal construction than a newer sapphire crystal. Also, rep pushers on modern daytona reps aren't that far off, it's not really worth replacing. Second of all, the problem with the modified 7750s are the seconds @ 6, not the center seconds. Yes, they both feed off the seconds wheel, but they're in different parts of the movement. You'd either need to graphite treat the modification plate or just turn it off altogether. Moreover, check freddy333's previous project on the modern daytona. I think he focused more on the profile and dial of the watch. Quote Link to comment Share on other sites More sharing options...
marcoxxx1984 Posted August 28, 2011 Author Report Share Posted August 28, 2011 Guys I would start from a 116520 base like this http://www.watcheden.net/rolex-daytona-chronograph-automatic-with-black-dial-i-12584-p-1.html Not a vintage one...

marcoxxx1984 Posted August 28, 2011 Author Report Share Posted August 28, 2011 Oh sorry I didn't mean plexiglass when I said clark tropic... I was thinking about the sapphire one and I wrote tropic.... Sorry Quote Link to comment Share on other sites More sharing options...
drury Posted August 28, 2011 Report Share Posted August 28, 2011 why not start out with a sec@6 daytona for a base? and have it serviced. then at least the watch would function as it should! Quote Link to comment Share on other sites More sharing options...

praetor Posted August 29, 2011 Report Share Posted August 29, 2011 (edited) very interesting. The link you gave us. It's a non chronograph A21J movement with seconds @ 6. They finally did it! It was always center seconds fake subdials before. This is a fairly new rep to the scene. Also, you should notice that watcheden mixed up the pictures (i.e. the profile and the back is a different watch - the solid gold daytona rep). As for the interchangability with genuine parts, the crown and tube should be a doable mod, as the parts and drill bits are fairly easy to come by. The tap on the other hand, difficult to find. If you plan to change the crystal or dial, it's fair enough to say that nobody knows what's going to happen because there's a fair chance that nobody knows the measurements of the watch case and dial, which means that you're likely to machine those crystal retaining parts... also make sure the movement is beating @ 28.8k. If that's not the case then you'd have further headache. Good luck. Edited August 29, 2011 by praetor Quote Link to comment Share on other sites More sharing options...

Ok I will not have chrono but who cares??? - Clark tropic - ofrei pushers - gen crown/tube + cg mods Thanks I don't think I'd spend money on a gen crown/tub for a watch that will have a frozen chrono seconds hand. Ofrei pushers are also probably an unnecessary expense. Quote Link to comment Share on other sites More sharing options...
kbh Posted August 30, 2011 Report Share Posted August 30, 2011 I'll bet it's the same movement as used in the UN Maxi Divers. That one seemed like a pretty good movement back when I owned one. Quote Link to comment Share on other sites More sharing options...
Pugwash Posted August 30, 2011 Report Share Posted August 30, 2011 Other experts? Are you still having holidays????? I just can't see the appeal. That's a lot of effort for, essentially, a bad replica. Quote Link to comment Share on other sites More sharing options...
Akira Posted August 30, 2011 Report Share Posted August 30, 2011 Since the modern Daytona cases are all wrong....I wouldn't bother with mods or gen parts. People with knowledge will spot it within seconds, with or without mods Just buy it and enjoy the watch the way it is. Quote Link to comment Share on other sites More sharing options...

HauteHippie Posted August 30, 2011 Report Share Posted August 30, 2011 Just think my father has the gen since 15 years and he never used the chrono. Never... I use the chrono on my 16520 quite a bit. But that's not the point. I just think that a rep of this caliber doesn't stand to improve much from aftermarket parts. There are bigger flaws than the ones you've identified for replacement.
