Stepping up in Rolex's range
The Pearlmaster exists to sit above the Lady-Datejust in Rolex's hierarchy — not by doing more, but by being more. Where the Datejust is a watch that can take jewellery, the Pearlmaster is jewellery that keeps time, and this reference makes that distinction plain: a fixed bezel set with twelve brilliant-cut diamonds, solid 18k yellow gold cast in Rolex's own foundry, and a bracelet built from rounded five-piece links designed to move with the wrist like a bangle rather than sit on it like a band. The Calibre 2235 inside carries a chronometer certification and a 48-hour reserve, which is a serious movement to find beneath a dial that may be mother-of-pearl or champagne or diamond-set Roman numerals depending on the variant. Rolex fitted it with a quickset date and a hacking seconds hand — the kind of practicality the watch wears quietly. The concealed folding clasp disappears beneath the links so the gold reads as unbroken from any angle, and the screwdown caseback and twin-lock crown account for 100 metres of water resistance that most owners will never need, but which speaks to how the case is actually built.

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?
17mm. 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.
Is it a men's or women's watch?
Listed as women's, though at 34mm it sits in the range that suits anyone.
