Franck Muller: Crazy Hours, the Revolution Tourbillon & the World Watch Rankings
The Direct Answer
Franck Muller is the hottest independent watch brand of recent decades — a Geneva-based manufacture founded in 1991 by master watchmaker Franck Muller, celebrated for its distinctive tonneau-shaped cases, colourful alligator straps, and the Crazy Hours complication: a watch whose numerals are deliberately scrambled around the dial, with hands that jump between positions to indicate the correct time. Franck Muller’s philosophy is to make the simple complex and the complex simple — a paradox that has produced some of the most original and technically ambitious watches of the modern era.
The Master of Complications
Franck Muller is a Swiss independent watchmaker who created his first complex watch movement in 1983. His guiding philosophy — “to make the simple structure complex, and the complex structure simple” — has driven every watch he has produced. In 1991, he formally established Franck Muller Watchland in Geneva, and every watch produced since has borne the inscription “Franck Genève” — a mark of limited production and individual craftsmanship.
Franck Muller watches are produced in strictly limited quantities. Each piece carries the “Franck Genève” signature — a guarantee of authenticity and rarity that has made the brand one of the most sought-after among serious collectors. The brand has earned the reputation as the maker of the “world’s most complex watches” — a title that reflects both its technical ambition and its willingness to challenge every convention of watchmaking.
The Crazy Hours: Genius Disguised as Madness
The Crazy Hours is Franck Muller’s most celebrated and most misunderstood watch. At first glance, it appears to be a watch with a broken dial — the numerals 1 through 12 are arranged in completely random order around the chapter ring. The 8 might be at the top where 12 should be. The 3 might be where 7 should be. The arrangement appears chaotic, irrational, impossible to read.
It is not. The Crazy Hours is a masterpiece of rational engineering disguised as apparent madness. The hands of the watch do not sweep continuously around the dial — they jump. At each hour, the hour hand leaps instantaneously to the next numeral, wherever that numeral happens to be on the dial. The minute hand sweeps normally. The result is a watch that tells the correct time — but requires the wearer to learn a new visual language to read it.
The mechanism that produces this jumping hour display is extraordinarily complex. A series of cams and levers stores energy during the hour and releases it instantaneously at the moment of the jump — a mechanism that requires precision engineering to produce a clean, instantaneous jump rather than a gradual movement. The scrambled numerals are not decoration — they are the visual expression of the jumping hour mechanism, making the jump visible and dramatic rather than subtle.
The Crazy Hours is available in Franck Muller’s signature tonneau case — a barrel-shaped case that is wider in the middle than at the top and bottom, inspired by the wine barrels of the Geneva region. The case is available in steel, gold, and with diamond-set bezels. The alligator strap — available in a wide range of colours — is one of the most recognisable design elements of any Franck Muller watch.
The Revolution: The 3D Tourbillon
The Revolution is Franck Muller’s most technically ambitious watch — a tourbillon in which the rotating cage moves not in a single plane but in three dimensions. The conventional tourbillon — invented by Breguet in 1801 — rotates in a single plane, counteracting the effect of gravity in one orientation. The Revolution’s three-dimensional tourbillon rotates in multiple axes simultaneously, counteracting the effect of gravity in all orientations.
The three-dimensional tourbillon cage is visible through the dial of the Revolution — a kinetic sculpture at the heart of the watch, its complex rotation visible in real time. The engineering required to produce a tourbillon that rotates in three dimensions — while remaining within the constraints of a wristwatch case — is extraordinary. The Revolution is one of the most technically complex watches ever made.
The World’s Top Watch Rankings: Where the Greats Stand
The prestigious Italian watch magazine Orologi — one of the world’s most respected horological publications — conducts an annual survey of the world’s finest watches across four categories. The 1998 results, covering 21 brands, provide a fascinating snapshot of the watch world’s hierarchy at the turn of the millennium:
Dream Watches (Most Desirable)
- Patek Philippe
- Vacheron Constantin
- IWC
- Audemars Piguet
- Chopard
- Rolex
- Zenith
- Baume & Mercier
- Breguet
- Franck Muller
Complicated Watches (Most Technically Complex)
- Vacheron Constantin
- Patek Philippe
- IWC
- Breguet
- Zenith
- Jaeger-LeCoultre
- Baume & Mercier
- Piaget
- Corum
- Vacheron Constantin
Technical Watches (Most Innovative)
- Patek Philippe
- Vacheron Constantin
- A. Lange & Söhne
- Zenith
- Breguet
- IWC
- Baume & Mercier
- Zenith
- Corum
- Franck Muller
Dive Watches (Best Sports/Tool Watches)
- Rolex
- IWC (Aquatimer)
- Omega
- IWC
- Patek Philippe
- Vacheron Constantin
- Breitling
- Bulgari
- Vacheron Constantin
- Hublot
The rankings reveal several consistent patterns: Patek Philippe and Vacheron Constantin appear at the top of virtually every category — confirming their status as the Holy Trinity’s dominant members. IWC performs exceptionally across all categories, reflecting its versatility as both a dress watch and a tool watch manufacturer. Franck Muller appears in both the Dream Watches and Technical Watches categories — remarkable for a brand founded only in 1991, just seven years before the survey.
In 1999, Hong Kong’s Famous Watch Forum conducted a reader poll selecting the world’s top ten watches: Patek Philippe, Vacheron Constantin, IWC, Breguet, Rolex, Jaeger-LeCoultre, Piaget, Cartier, Chopard, and Audemars Piguet. The differences between the Italian and Hong Kong rankings reflect the objective reality that watch preferences vary by market, culture, and individual taste — a natural expression of the diversity of the watch world.
Franck Muller’s Design Philosophy
Franck Muller’s design language is immediately recognisable: the tonneau case, the large Arabic numerals, the colourful alligator straps, and the sense of playful extravagance that distinguishes his watches from the restrained elegance of the Swiss establishment. Where Patek Philippe whispers, Franck Muller shouts. Where Vacheron Constantin is classical, Franck Muller is baroque.
This extravagance is not superficial. Beneath the dramatic dials and the colourful straps are movements of extraordinary complexity — the Crazy Hours mechanism, the three-dimensional tourbillon, the minute repeater, the perpetual calendar. Franck Muller’s watches are technically serious watches dressed in theatrical clothing.

It is also celebrated for the Revolution three-dimensional tourbillon and for its philosophy of making the world’s most complex watches.
What is the Crazy Hours watch?
The Crazy Hours is a Franck Muller watch with numerals arranged in random order around the dial. The hour hand jumps instantaneously between positions at each hour, pointing to the correct numeral wherever it appears on the dial. Despite its apparently chaotic appearance, the Crazy Hours tells the correct time — it simply requires a new visual language to read it.
