I still prefer the GMT II, which I think is the best watch Rolex make. But I did try the YM 40 on back to back with a Sub before buying one. Next to it, the Sub was so clunky. It felt more like a Seiko.
The problem with the YM is, posting pictures of it is usually pointless. Online it just looks like a silvery watch. In person it’s an absolute feast of texture wrought in platinum, rhodium and stainless steel.
Leave it on a watch stand in your place, somewhere very out in the open. If it disappears, problem solved and you learned who you can’t trust. If not, it continues to tell you your visitors are honest.
