The colored numerals of a Franck Muller Crazy Hours Color Dreams dial, close up

Franck Muller

Franck Muller rejected the pink-it-and-shrink-it approach, and Time+Tide calls him an early advocate of “real” watches for women. His ladies’ Cintrée Curvex Tourbillon holds one of the smallest flying tourbillons made, 11.6mm across, in a case curved to wrap the wrist. The Mystery watches replace hands with turning discs, and the Round Triple Mystery of 2025 reached the finals of the Grand Prix d’Horlogerie de Genève for women’s complications. Many of his other women’s watches use quartz movements in gem-set cases.

I can source any watch, new or used, even very hard-to-get. I chose these examples to guide you.

French pop artist Jisbar redrew every numeral for this Crazy Hours, spelling out ONE and writing 5 as the square root of 25. The numerals appear out of sequence, and at each new hour the hour hand jumps to the correct numeral.

More about Franck Muller

Franck Muller, a Geneva-trained watchmaker, made his name in the 1980s with complicated watches. In 1991 he founded the company with the case maker Vartan Sirmakes. It works from Watchland, a mansion in Genthod, outside Geneva.

In 1992 the company announced a watch it called the most complicated wristwatch in the world, and it later made the Aeternitas Mega 4, with 36 complications. Its Cintrée Curvex case curves in three directions. The Crazy Hours of 2003 scrambles the hour numerals, and a jumping hour hand still shows the right time. The company remains independent.
