I recently bought an "economy" and a "high quality" rep from Silix. A big bang Hublot with the a21j movement (economy) and a Dior for the wife with a quartz movement and full ceramic bracelet. I also bought a couple of watches in the "specials" section. I am fairly new at this but I do own a gen Tag F1 and a gen Omega Seamaster so I have some frame of reference. The specials I bought were a rolex daytona and an omega seamaster chrono to use as daily replacements for the gens. I would steer clear of the "specials". They are not even worth the $30 I paid although I am not sure what I was expecting for $30. lol. I figured if they were really crap I would just toss them, which I did. The bracelets in particular were really cheap and the size and weight was nowhere near the gens.
As for the Hublot and Dior, I paid $72 for the hublot and $108 for the dior. The hublot is nice, good quality rep for the price and the dior is also really nice. The one thing I'd like to point out though is that the price doesn't only reflect the movement of the watch. The hublot has a mineral or synthetic crystal and not sapphire. Also there is no AR on it. The chrono is non functional and the bracelet clasp is a pain to get on and off. It also loses 2 minutes a day! But I was told that I can get that fixed although I would rather not have to. So the price will reflect the overall quality of the rep. In my opinion, best to drop an extra $100 and get something really nice which is what I will be doing. Looking at going with perfect clones next.
That's been my experience so far. Hope that helps.
