I've been there a few times in the last couple weeks buying stuff for my new apartment. Availability is hit or miss since dealer paranoia seems to vary day to day. I've seen some pretty interesting stuff though, some Pams, Patek Nautiluses (the one with complications) on steel, AP Divers (V1 with probably asian clone movement), and the cream of the crop, an a21j AP RO 15300 that I picked up immediately. It's the only a21j version I've seen with proper angular dial markers, and the only 15300 I've EVER seen with a solid caseback. The Hublots of all sorts, B&R's, and AP chronos are on display plus your usual bevvy of dress watch reps. The other stuff is available, usually you find someone muttering "Rolex," tell them what you want, and wait on a corner while a runner grabs it for you. It's totally worth a trip if you're there. It's fun trying on a couple random watches you might otherwise not really consider but that look pretty good in person actually, i.e. a JLC Reverso with the best skeletonized asian movement I've seen yet
