Rolex Day-Date 40

 The Book of Rolex Day-Date 40 — 18kt White Gold, Olive Green Anniversary Dial

History: The Day-Date debuted in 1956 as the first waterproof, self-winding chronometer wristwatch to show the full day of the week spelled out in a window alongside the date. Rolex reserves it exclusively for precious metals — all gold or platinum — and it quickly earned its nickname as "the President's watch," worn by world leaders for seven decades.

The watch: This edition centers on the modern 40mm white gold Day-Date, launched in 2016 with the new-generation calibre 3255 — 70 hours of power reserve and Rolex's Chronergy escapement — wrapped in the iconic President bracelet. The hero here is the olive green sunburst dial, the celebrated "anniversary" face that has become one of the most collected modern Rolex dials, with the fluted white gold bezel catching the light around it.

In the news: The olive dial remains one of the hardest Day-Date configurations to find at retail, and white gold examples steadily hold their value — not just a dress watch, but one of the most quietly desirable references Rolex makes.
