The DangDong 4130 used in the CF/BTF Daytona's are generally considered to be the most robust Chrono movements around with failure rates around ~1% (which is on par if not better than stuff coming out of Switzerland). The low-end Daytona reps using Asian 7750's would be much more prone to failure but there is so much other stuff wrong with those reps using the 7750 (due to the size of the 7750 and all the case shape and height discrepencies it causes none would be NWBIG. These failure rates were provided by a TD on Reddit.
I think CF V3's (Black and Panda) are NWBIG IMO - I have both (but not Gen's). *Maybe* you swap a gen crystal if you want an extra 5% in clarity, but other than that a good service and an oil bath for the bracelet and it's as close to Gen as anyone in their right mind needs.
