Actually the current A7750 has a fine track record imo.
Over the years i have had a couple watches die on me,taken to my local watchsmith,up running in a couple minutes. Dirt in a gear or a drop of oil...etc,minor stuff but common.
Look for a watchsmith in your phone book and stop by with it,you might find its an easy fix as well. If you find one you are happy with,do take any future purchases to him for a checkup when you get it,doesn't hurt. Good luck.
