Nice!

 

Btw what is considered to be OK accuracy for Asian 7750 Chrono Auto movement? I have a rep that gets 2-3 minutes behind in 24h, is that considered to be OK?

I regulate my A7750s to - 0/+4 seconds a day. My IWC 3777 which I'm wearing this week I have had over a year now. I set it on Monday afternoon and it's now about 7 seconds fast after 2 days, wearing all the time. That's on the top limit for me but I'll probably leave it for now. The accuracy will drift a little over weeks too and these are not built like the gens. Not bad though.

 

2 to 3 minutes a day needs regulating.

7750s can, with a little patience and the right equipment, be set to work within COSC standards of +/- 4 seconds per day.
