So I made my first rep order for 2 Noob factory Rolex reps. One a classic Sub and the other a Deep Sea. Both with the 21J as most criticism I heard was on longevity of the movement and noise, which neither truly bothered me. I received both models, and immediately noticed a problem with the deep sea. It simply will not keep time. It loses at least 15 minutes each hour, sometimes more, sometimes less. the date wheel jumps quite a bit (as if truly loose, not just mis-aligned.)
Oh well I think, I will send it back, the SUB seemed to be good. Wait a day. now it loses time, in about 5 minute increments, randomly. I looked t it last night and it was 5 min slow. Weird, had been perfectly accurate for 36 hours. No worry, set it forward. Kept an eye on it was fine, fine, fine, and then suddenly 5 minutes slow. I had checked it probably less than 30 minutes prior. Just suddenly lost 5 minutes.
So now I am 0 for 2 on the 21J.
My question is, is the movement really that bad, or are the examples I got just really bad?
