My two cents:
This PAM has 21j, and works perfectly. Just 2 days ago I gently shaked for 1 minute my A7750 Chopard MM, in one hand, and my new Yaht-Master with 21j in another hand. A7750 worked 25 hours, but YM still beating. OK? Now, tell me that 21j is sheeeet.
I have few quartz, for one reason only - I work at home, and wear watch only if I'm going out, it's about 2-3 times a week, and I don't have watchwinder yet, so, I'm sick and tired to set up the time and day/date every time I war the watch. But quartz keep perfect time all the way.
Ofcourse, when I'll buy watchwinder, situation will change, but for now- I'm quite happy with few good looking quartzes.
3/4 of my reps has 21j, and absolutely all of them works perfectly for years, even if I don't wear them too often.
And now these 21j is just great. Especially for the price. Oh, yeah... we're talking boobs here, I forgot...
OK, asian, with midsize boobs, tanned skin, looooong black hair, mystery in the eyes, smooth skin... full lips... hey, I have it already.
