I have so,e experience with these clocks, a couple of years ago I stumbled upon them whils looking for a clock for myself, I started importing them from a dealer in China I found on Alibaba, and selling on eBay at a great profit, it lasted about 5 months before rolexs solicitors complained and I got banned for life from selling on eBay, I only had Rolex daytonas, subs, gmts, etc.
so to answer your question as far as I know there are not different version like a replica watch, they are what they are,having said that the daytonas I have are better than the ones on trustys site,
they are are quite nice clocks, stainless steel with glass, luminous hands and smooth running second hands, subs etc have working date wheels
if it's a Rolex your after post a pic or link and I will let you know if it's the same as I dealt with, I've tried to upload pics of the ones I have but cannot as pics are too big,
