Stepping up in Rolex's range
The Day-Date has always been the watch Rolex made for those at the top of whatever room they were in — introduced in 1956 as the first wristwatch to spell out the day of the week in full, it has carried that brief ever since. This reference, the 118206, belongs to the six-digit generation that arrived in 2000, and it is distinguished by something the specifications table cannot quite convey: the Ice Blue dial is not available on any other material in the Rolex catalogue. That colour, a pale glacial silver unique to solid platinum cases, is Rolex's own reserved signal — you cannot have it in gold. At 36mm the case sits where the original Day-Date always did, and 217 grams of platinum means it registers on the wrist with a weight that no gold or steel reference produces. The calibre 3155 allows both the day and date to be corrected independently, which sounds minor until you have used a movement that cannot. The President bracelet's Crownclasp leaves only a small applied crown visible at the wrist — no visible opening mechanism, no visible seam — and link sizing requires screw pins rather than a push-button system, which is less convenient but considerably more precise once set.

Learn more about Rolex
Hans Wilsdorf founded Wilsdorf & Davis in London in 1905 with his brother-in-law Alfred Davis, importing Swiss movements and casing them in England. He registered the name Rolex in 1908 — short, pronounceable in any language, and easy to fit on a dial.
Wilsdorf's conviction was that the wristwatch, then regarded as a woman's ornament and hopelessly fragile, could be made accurate and durable. He proved the first half in 1910 by obtaining the first chronometer certification for a wristwatch, and the second in 1926 with the Oyster case, sealed by a screw-down crown and caseback. Mercedes Gleitze swam the Channel wearing one in 1927, and Wilsdorf bought the front page of the Daily Mail to say so — arguably the first modern watch marketing campaign.
The Perpetual rotor followed in 1931, giving automatic winding in a form the whole industry eventually copied. The company relocated to Geneva during the First World War to escape British wartime duties.
The professional models arrived in a compressed burst in the 1950s: Submariner, Explorer, GMT-Master, Milgauss, and later the Daytona. Each was built for a specific job — diving, exploration, aviation, laboratory work, racing — and each became a design template.
Wilsdorf left his shares to a private foundation on his death, so Rolex answers to no shareholders. It remains the largest producer of certified chronometers in Switzerland by a wide margin.

Frequently asked questions, and things you should know about this watch
Can I swim with it?
Yes. At 100m it is rated for swimming and snorkelling, though not for diving.
Water resistance explainedWill the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Sapphire, mineral and acrylic comparedDoes it need a battery?
No. It is automatic — the motion of your wrist winds it, and there is no cell to replace.
Quartz, automatic and solar comparedHow long does it run for when it's not worn?
About 48 hours fully wound — enough to survive a night off the wrist, but not a full weekend.
What size strap does it take?
20mm. Any strap of that width will fit, and on most modern watches quick-release bars make the swap a two-minute job with no tools.
Will it fit my wrist?
Lug-to-lug is 43.5mm, which suits wrists from roughly 15cm (6 inches) upward.
Lug-to-lug decides fit more than case diameter does.
How to size a watch to your wristIs it a men's or women's watch?
Listed as unisex, and at this size it suits any wrist that takes the dimensions.
