The Yacht-Master's steel-and-rose-gold case puts it in a different bracket of my catalogue than the mono-material sport watches — it's positioned as nautical-leisure rather than dive-tool, even though the 100m rating is identical to watches I'd classify as genuine tools. The brown dial is an unusual choice at this size, and it scores well on my distinctiveness axis precisely because so few references in this catalogue use that color at all. At $16,420, the two-tone construction accounts for most of the premium over a full-steel equivalent — you're paying for the gold content and the finishing between the two metals, not for extra water resistance you're not getting.
