Wow, lots of 2018 Santos reps hitting the market. Unfortunately, none of them are really in ready to be labeled super reps yet. The GF version seems pretty nice. The crystal seems decent from the pictures and it does the best job matching the right color of the blue spinnel used in the cabochon (the Kor, BVF and V6F use a stone that too light of a color--more like a corflower sapphire). The bracelet and screws look ok on the GF, but the engravings look a bit weak in the pictures. A little too thick on the bracelet and not deep enough. Also the serial number is a little too thin and shallow on the caseback. The V6F and Kor do a better job here. I would need to see some better pictures though to confirm. The most significant issue with the GF--at least in the pictures and video posted to puretime--is the lower quality print work on the dial. You can see some places where ink (or whatever they use for the printing) missed a spot or ran a little bit. It probably isn't noticeable outside of macro-photos, but it's not close to the level of the gen. The Kor and V6F do a better job with getting the print quality correct. I can't speak about the font without studying the gen a bit more, but they all seem reasonably close to the gen (Cartier font isn't as hard to nail down as Rolex font, so this shouldn't be a huge surprise). None of them are doing a great job on the hands as far as I can tell. All of them are using painted hands, versus heat blued hands used on the gen. Moreover, if you look closely at the pictures on puretime's site, you can see there are paint dots or other remnants along the sides of the hands---particularly the hour hand. You won't see that on gen cartier. These aren't necessarily glaring tells, but show where there could be some improvement in quality on these reps. They get the big things right, but skip some of the finer details. Not bad though for reps under $500.00. I want to see more pictures of the GF---hopefully someone here can post some QC pictures so we can get a better look.
