For those of us who have been out of the game & not following the significant advances the factories have made in fake Daytonas in the past 2 or 3 years, I think you should watch this. & make sure your cardiologist (& banker) is on speed-dial when you do. You will NEED to spend some cash.
As some have guessed from my 1st post, my original plan was to replace all the components that have (minor) issues with gen parts. The result will effectively be a gen Daytona -- all the components you see to operate & use the watch will be genuine. As it is, in 24 hours, the movement gained 1 second, which is better than any other mechanical watch I own. So it certainly is not lacking anything, performance wise, relative to the gen. & I cannot describe how much of a cloaking effect having the correct wrist profile has on the watch's few visual inaccuracies. This is the 1st fake Rolex in my experience that functions & looks 100% like the real thing from an arm's length away. Gone are ALL of the seconds @ 6 7750's clunky feel, twitchy functionality & well-known unreliability.
The BIG KAHUNA (I got mine from Andrew (trustytime -- see item ROLDYT0357B) is so good that, after living with it for the past 24 hours, I am not so sure it is worth the time/effort to replace anything other than the dial. & even that would fool someone like me unless I donned a loupe & began poking around at close range. As I mentioned above, this thing is a head-turner (in the best of ways) out of the box. So my new plan is to live with it for a week & then decide whether its few (very) minor inaccuracies (dial font, hands, crown/tube, bezel, balance & bridge, noisy rotor & off-color reversing wheels) merit gen upgrades (which are still sitting on my bench -- that is how good this thing is out of the box)?
