I've had mine for about a week and so far it's been great. I bought mine from Vmena, who originally purchased it from King, so I don't know if that has any bearing on things. It's my first A7750 so I'm quite careful about how I use it (don't change date after 10pm, reset the chrono between 10 and 2 ect.) I haven't had it serviced yet as I'm still waiting for a quote from a local watch repairers, but to be honest I may just chance it.
The power reserve seems to be a bit low, but I've since read that the A7750 only winds in one direction (didn't know this before purchase) and perhaps this is why I'm finding it not lasting as long as my gen Aquaracer or copy Rolex Sub Eta. I still get about 18-24hrs if I have it on all day and take it off when I get home from work. Maybe I'm being too picky, after all it is a rep.
The movement is unaltered and the seconds sub dial at 9 o'clock sweeps cleanly without any skips or jumps. However when using the chrono, the minute hand (at 12 o'clock) clicks forward when the second hand reaches 58 seconds. For me this isn't a big deal as I don't use the chrono and besides, if I was wanting to time something accurately I wouldn't use a copy anyway
The chrono buttons feel solid when you push them in.. there's a definitive 'click' which feels very similar to my gen Aquaracer. I doubt you'd be able to accidentally activate the chrono and risk any damage to the A7750 while out and about wearing it.
The crown pulls out (doesn't unscrew) so I'm not sure what that means for water resistance? I don't wear my watches in the shower or out scuba diving (scuba what?) so this doesn't bother me
I've got both the SS and Rubber straps. They both feel extremely well made - the SS bracelet particularly. The polished links are actually separate to the brushed stainless steel sections. Resizing was actually very easy despite what some other members have said, although we did use a proper tool. This may also have been aided by Vmena having cleaned and oiled it before sending it to me - thanks Vmena! The release catch also feels very well made - in my opinion much better than the Omega Ultimate PO release clasp. The ends of the links all seem to be cleanly finished, except for the last ones, which are only noticeable when not wearing the watch.
I actually bought this watch for the rubber strap, but because it uses a deployment buckle (which again is very well made) and having small wrists (thanks mum ) it just doesn't fit on my wrist correctly. I'm not disappointed though, the SS is fine.
The dial is extremely well replicated. I haven't gone as far as to measure the sizes of the hour markers ect., but comparing it to a gen in a ADs window made me appreciate the copy even more. The only niggle I have about the dial on this model, is that the chrome finish around the sub dials at 12 and 6 have a slightly jagged edge where they meet the pattern around the outer edge. Noticeable only up close and for me, not a big deal. If this is the type of thing that bothers you, there are three other Carrera models where I think this problem doesn't exist because there isn't a patterned edge, so pick one of those (brown's my next favourite!).
The date is slightly off centre - towards the top right, however the font looks to be correct. It doesn't bother me too much and on some days it actually appears centred. I think this is something that can be changed, but I'm not sure?
The only lume is on the hour and minute hands, which unless it's held under a lamp for several seconds, doesn't really do anything. This is also the same on my gen Aquaracer, so maybe Tag lume is really crap and it's actually a good copy
In certain light the red hands sometimes, to my eyes, look cheap. I can't really explain it, they just don't look to have the same quality as the rest of the watch. They look like they're plastic (I'm not sure, are watch hand made of metal or plastic?) so again, if this is something that might bother you, then pick one of the other models available.
A couple of small points - There’s no AR on the crystal (the same as the gen), it has a glass back so you can see the nicely engraved rotor and there’s also the same engravings as the original.
If you can live with the A7750 then it’s a great watch. Very close copy. I have no problems wearing it around friends who wear expensive gens and would be surprised if an AD spotted it wasn’t real without having a proper inspection. Buy it and enjoy it!
