I have ten reps with A7750 movement and they are all running well,only one has been serviced. I agree with Andrew In reguards to the A7750 comming along way In the last several years,It really Is a very good movement. Also remember that most high end Swiss made timepieces are autos,the quartz ticking sec hand will be a dead give away to anyone who knows watches. There are some very nice tag reps,spend some time In the "tag area" of this forum. Good luck on your first rep purchase. Mike
