Update --
After 24 hours, the watch has developed a minor, but interesting problem as a result of the gen parts transplant -- (on-the-wrist & w/o using the chrono) timing spec went from 1sec/day fast to 1sec/day slow. Because this error is still well within Rolex's spec for the Daytona, it is not worth the time/effort to correct.
It is quite a feat for a fake Rolex to exceed Rolex's timing spec to begin with. But it is a testament to the 4130's design & the factory's implementation of that design for a fake Rolex to maintain anything close to its original timing spec after such major surgery (balance & bridge replacement). & to see the gen balance hit the ground running (accurately & without any timing adjustment) in a fake is quite an accomplishment.
If you are a Daytona fan, appreciate fine craftsmanship & can afford the (high) price tag, you owe it to yourself to get 1 of these. Trust me on this, even in out-of-the-box form, it is destined to become a classic. As I mentioned earlier, I would have no problem wearing 1 of these watches -- without ANY mods/parts swaps -- as daily wear. & if you have the cash, inclination & skills (or a proper watchmaker willing to do the work for you) to hunt down & swap a few parts for gens, you will end up with a visually, tactilely & functionally genuine Rolex Daytona for a fraction of the MSRP (which only a very select few end up paying anyway) & without all of the games & hassles required of ADs and grey-market flippers.
