Rolex Sky-Dweller336239-0002

The Sky-Dweller packs an annual calendar and a second time zone into a case that's still 100m rated — genuinely useful complications that most brands would split across two separate watches. This 336933-0001 is 42mm steel-and-gold with a black dial, $28,800, and the Ring Command bezel that sets both functions without extra pushers is the detail that keeps it off my list of over-complicated watches. On my functions-per-complexity axis this scores well: two real complications, one crown, no compromise on the case sealing that every other Rolex in my catalogue shares.
