Well, in the first point, if you're leary of the A7750, you're likely not going to be buying any chrono reps anymore. Notwithstanding any dealer claims to the contrary, virtually every chrono rep has an A7750 now (and they have for about a year). The ETA movements dried up a long time ago. In general, an unmodified A7750 (with running seconds at 9) is a good movement. There have been massive problems with the modified seconds at 6 and seconds at 12 (although I'm told these issues will be resolved with some new Solita movements coming out in reps later this year or early next). And there will be bad batches of A7750s occasionally. But as a GENERAL rule, the A7750s are fine. That being said, do NOT, under any circumstances, set the date between the hours of 8:00 and 4:00. This will strip the gears of the watch very quickly. But this is true of any 7750, not just the A7750.
