Stepping up in Rolex's range
The Oyster Perpetual sits at the centre of what Rolex does: a clean, unadorned case, a self-winding movement, and nothing superfluous. The 177200 is the 31mm expression of that idea, sized to wear close to the wrist without disappearing, and produced in a range of dial colours — the blue here among the more striking — that gave buyers genuine choice within a deliberately restrained design language. It ran in production until around 2020 and sold steadily throughout because it made no compromises in the things that matter to daily wear. The calibre 2231 inside carries chronometer certification, which at 28,800 vibrations per hour means it is held to accuracy standards most movements in this category never attempt. At 10.5mm thick the watch slides under a cuff without protest, and the Oystersteel bracelet — Rolex's 904L alloy, noticeably more resistant to surface scratching than standard steel — holds its polish through the kind of use an everyday watch actually sees.

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.
Will the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Does it need a battery?
No. It is automatic — the motion of your wrist winds it, and there is no cell to replace.
How 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?
16mm. 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.
