I could probably pick out one tell. AR on the GC grand carrera) and 1887 are not gen like. But I haven't owned an 1887. The stock AR is Similar to IWC BP out of box. I have a black GCC17. Thought about having an AR mod. But used the money for a gen gator strap. I could live with the stock AR. I love the watch but for $400, I'd rather get a Noob or H-fact PAM. Hope this helps
