In 1924, the same year that Britain’s first Labour government took office and the Empire Exhibition opened, Watches of Switzerland began a mail order business, selling imported watches from its office in the City of London.

Today, as it celebrates its centennial, the Watches of Switzerland Group has more than 200 showrooms in Britain and the United States, employs more than 2,900 people, sells more than 80 watch brands and reported revenues of 1.5 billion pounds (about $2 billion) in its latest fiscal year, which closed in April.

“Today, we’re really proud of our business — we’ve hit almost $2 billion globally, and it is 50/50 between the U.K. and the U.S.,” Brian Duffy, the company’s chief executive, said in a recent interview. ”And we’ve only been in the U.S. since 2018, and here’s still plenty of room for growth.” (On Oct. 4, the company announced it had bought Hodinkee, the watch website based in New York.)

To commemorate the occasion, the company has been releasing a series of limited-edition timepieces from brands such as Cartier, Bulgari, TAG Heuer and Zenith, mostly fitted with straps in Watches of Switzerland’s signature blue color. And on the back of the golden case of a 100-piece Tank Louis Cartier, under the Cartier and Watches of Switzerland logos, the inscription 1924-2024 marks the anniversary.

Along with the special editions, the company held an event called “Time to Inspire” in August at the London headquarters of the Prince’s Trust, a charity that King Charles III, then Prince of Wales, established in 1976 to help vulnerable young people. The event included workshops, networking and a series of talks by personalities such as the actor John Hannah (“Four Weddings and a Funeral,” “Agents of S.H.I.E.L.D.”) and the former German soccer player Thomas Hitzlsperger.
