Hans Wilsdorf was working as a clerk at a watch exporter in La Chaux-de-Fonds, Switzerland, when he made the bet that would build Rolex. The year was 1905. He had moved to London, opened a firm called Wilsdorf & Davis with his brother-in-law Alfred Davis, and decided to stake the business on an object that gentlemen of the Edwardian era openly mocked: a watch worn on the wrist.
At the time, a man wearing a wristlet was the kind of thing that got you laughed out of a London club. The wristwatch was a lady’s bracelet with a tiny dial on it — jewelry, ornament, frippery. Real men carried pocket watches on chains, tucked into waistcoats, attached to fobs. The wrist was for women.
Wilsdorf bet against the joke. Within thirty years he had inverted the entire grammar of how men told time.
The pocket watch was a uniform
To understand why the wristwatch was funny, you have to understand what the pocket watch meant. By the late nineteenth century, the gold pocket watch on a chain across the waistcoat was the central piece of male adornment in the industrialised West. It signified punctuality, sobriety, employment, and class. A railway conductor had one. A banker had one. A vicar had one. The act of pulling it out, snapping the cover, checking the time, and snapping it shut again was a small ritual of competent manhood performed dozens of times a day.
Women, by contrast, had been wearing small timepieces on bracelets since at least the early nineteenth century. Through the nineteenth century the form stayed firmly feminine. These were jewelry pieces — enameled, gem-set, delicate. The dial was almost incidental to the bracelet.
So when a man strapped a watch to his wrist in 1900, he was wearing what every observer instantly read as a woman’s accessory. Period sources record the standard joke: a chap might as well wear a skirt.
Why the joke was sticky
The ridicule wasn’t trivial. Manhood in the Edwardian period was what social psychologists now describe as a precarious social status — something earned, something that could be lost, something policed constantly through small public signals. The wrong hat, the wrong handshake, the wrong accessory could cost a man standing among other men.
This is the mechanism that makes gendered objects so durable. A wristwatch in 1903 didn’t just look feminine; wearing one announced that the wearer either didn’t know the code or didn’t care, and both readings were costly. The pattern persists today — adolescent boys police one another’s masculinity through ridicule in ways that echo the club-room laughter that greeted the first wristlet wearers.
The barrier wasn’t engineering. Small movements existed. Straps existed. The barrier was social, and it was loud.
The clerk from Kulmbach
Wilsdorf had been born in Kulmbach, Bavaria. Both parents died when he was young. He and his siblings were raised by uncles who sold off the family ironmongery business and used the proceeds to send the children to good schools. Hans learned English, French, mathematics, and the habits of a careful correspondent. By nineteen he was in La Chaux-de-Fonds, the watch-making capital of Switzerland, handling export ledgers and learning what made a movement reliable.
What he saw in Switzerland, and what most of his London contemporaries missed, was that small precision movements were getting good. Aegler, a workshop in Bienne, was making lever-escapement movements small enough to fit a lady’s bracelet but accurate enough to keep proper time. Wilsdorf placed an order for Aegler movements before he had a company to sell them through. The order was so large it reportedly worried his Swiss suppliers.
In 1905 he opened Wilsdorf & Davis. The plan, written down in his own correspondence, was to put Aegler’s small movements into wrist cases and sell them to men.
The name designed to fit a dial
Wilsdorf understood that to sell a wristwatch to a man, the object had to stop reading as ornament and start reading as instrument. The name on the dial mattered. “Wilsdorf & Davis” was too long, too foreign, and too obviously a merchant’s mark. He wanted something short, pronounceable in any European language, and visually balanced.
He later said the word “Rolex” came to him on the upper deck of a horse-drawn omnibus in London. Five letters. Symmetrical. He registered the name as a trademark in 1908.
The bigger problem was accuracy. A wristwatch sat on a moving arm, exposed to sweat, dust, and temperature swings — conditions far harsher than a waistcoat pocket. If the new object was going to be taken seriously by men, it had to keep time better than the pocket watch it was replacing.
Wilsdorf sent Rolex movements to horological institutes for certification. A Rolex wristwatch earned precision certificates that had previously been reserved for marine chronometers used to navigate ships across oceans.
The watch on the wrist was now, by official measurement, more accurate than most pocket watches in most waistcoats.
The war that killed the joke
The thing that finally broke the prejudice was not advertising. It was the trenches.
An officer in 1914 trying to coordinate an artillery barrage with an infantry advance could not fumble in a greatcoat pocket for a chained watch under shellfire. Synchronised attacks required synchronised time, read instantly, on the wrist. The British War Department issued wristwatches — “trench watches” — to officers in enormous numbers. Soldiers came home in 1918 having spent four years checking the time on their wrists as a matter of life and death. The accessory that had been a punchline in 1905 was, by 1919, a badge of having served.
The cultural inversion was almost total. Within a decade the pocket watch became the old-fashioned object, associated with grandfathers and undertakers. The wristwatch became the modern object, associated with pilots, drivers, soldiers, and engineers. Objects can shift between gender associations dramatically, and this moment stands as one of the cleanest twentieth-century examples of a gendered category flipping inside a single generation.
The waterproof case
Wilsdorf did not stop at accuracy. In 1926 Rolex patented the Oyster — a hermetically sealed case with a screw-down crown and caseback, the first genuinely waterproof and dustproof wristwatch case.
To prove it, Wilsdorf gave one to a young English swimmer named Mercedes Gleitze, who wore the Oyster around her neck during a Channel swim in 1927 — a ten-hour crossing in cold water. The watch kept perfect time. Wilsdorf took out a full front-page advertisement in the Daily Mail announcing the result. It was the first celebrity endorsement in modern watch marketing, and it converted the wristwatch from a fragile ornament into an instrument that could survive the open sea.
Why the bet worked
Wilsdorf had read three things correctly that his competitors had read wrong.
He saw that the social ridicule was not based on the object’s properties but on its associations, and that associations can be moved. He saw that the way to move them was to overload the new object with masculine-coded performance — chronometer certificates, war service, ocean crossings — until the old reading became inaudible. And he saw that small precision movements were a technological wave that was going to break with or without him; he just had to be standing in the right place when it did.
The Wilsdorf Foundation, which he established in 1945 after the death of his wife May, still owns Rolex today. The company does not publish financial results, but industry analysts at Morgan Stanley estimated its 2023 revenue at roughly 10.1 billion Swiss francs, making it by a wide margin the largest Swiss watch manufacturer.
The orphan’s wager
The wristwatch on the arm of every commuter, every pilot, every nurse checking a pulse is the residue of one Bavarian clerk’s bet that a piece of ridicule was thinner than it looked. The mechanism Wilsdorf exploited — the way social mockery enforces what objects men are allowed to wear, and how quickly that enforcement can collapse when the object proves itself useful — is the same mechanism that operates in conformity pressure across completely different settings. Ridicule is loud. It is also brittle.
Wilsdorf died in 1960 in Geneva. He had outlived the joke by fifty-five years and was buried wearing a wristwatch.
