Franck Muller earned the title “Master of Complications” not from critics or journalists — but from the horological establishment that watched a 30-year-old Geneva School graduate disassemble and reassemble some of the most complex antique pocket watches in private collections, then proceed to invent complications the industry thought impossible. The Cintrée Curvex case. The Crazy Hours dial. The Tourbillon Banker. The world’s most complicated wristwatch at the time of its creation. At Diamond Source NYC, we carry authenticated Franck Muller timepieces for collectors who want a watch with a genuine personality and complications that go beyond certification into genuine invention. With 30+ years in Manhattan’s Diamond District, we know exactly what we’re selling.

About Franck Muller
Franck Muller was born in 1958 in Genthod, near Geneva. He trained at the Geneva School of Watchmaking and spent the 1980s restoring some of the rarest and most complex antique pocket watches in existence — pieces by Breguet, Patek Philippe, and other 18th-century masters. This intimate knowledge of historical complications gave Muller a reference library that most watchmakers never access. In 1991, he founded Franck Muller Watchland with business partner Vartan Sirmakes.
The brand's ascent was extraordinary — within a decade, Franck Muller had produced the world's most complicated wristwatch, invented the Crazy Hours complication, registered the Cintrée Curvex case shape as a trademark, and dressed the wrists of collectors across every continent. The "Watchland" manufacture complex in Genthod houses the entire production chain under one roof — one of the few fully integrated manufactures in Swiss watchmaking.
Franck Muller Collections
Cintrée Curvex
The case shape that defined Franck Muller. The Cintrée Curvex curves on three axes simultaneously — a manufacturing achievement that required custom tooling no other brand had. Oversized Arabic numerals, dramatic proportions, extraordinary dial legibility. Everything Franck Muller stands for is expressed in this case.
Crazy Hours
Hour markers arranged in deliberate disorder — 12, 9, 1, 8, 2, 10, 6, 4, 11, 5, 7, 3 — while the hand still tells correct time by jumping in a programmed sequence. A mechanical joke that requires genuine complication engineering to execute. The Crazy Hours is Franck Muller's most playful invention and most talked-about watch.
Vanguard
Franck Muller's tonneau sport collection. Larger case proportions, vibrant dial inserts, modern materials. Available with date, skeleton, chronograph, and tourbillon complications. The Vanguard is Franck Muller for clients who want the complications without the formality of the Cintrée Curvex.
Master Banker
Triple time zone display inside the Cintrée Curvex case. Three independent time zone subdials. Designed specifically for international finance professionals — a watch as functional as a Bloomberg terminal, built with the finishing of haute horlogerie. The Master Banker is Franck Muller at its most purposeful.
Tourbillon Collections
Franck Muller's tourbillon references span from the Cintrée Curvex Tourbillon to the Aeternitas Mega — the world's most complicated watch at the time of its launch in 2009, featuring 36 complications. Tourbillon Banker, Tourbillon Imperial, Revolution tourbillons — Muller has produced more tourbillon variants than almost any other manufacture.
Color Dreams
Franck Muller's most vibrant expression. Multicolor dials, colored numeral treatments, diamond pavé set on the Cintrée Curvex case. For clients who find the restraint of Swiss watchmaking limiting — and want a watch that announces itself with genuine joy.
Why Franck Muller Belongs in a Serious Collection
Genuine "Master of Complications"
The title was not self-assigned from a marketing department. Muller earned it by restoring historical movements no living watchmaker understood, then reinventing them. The Aeternitas Mega — 36 complications — was certified the world's most complicated wristwatch by the Guinness Book of Records.
The Cintrée Curvex — a trademarked shape
The Cintrée Curvex case shape is trademarked. No other watch brand can produce this specific three-axis curve. This legal exclusivity means that any collector who wants this case — and millions do — can only get it from Franck Muller.
Watchland — fully integrated
Franck Muller's Watchland facility in Genthod houses movement manufacture, case production, dial ateliers, and assembly under one roof. Very few manufactures achieve this level of vertical integration. It is the physical embodiment of "invented and made here."
Celebrity and collector following
Franck Muller watches are collected by heads of state, athletes, and musicians across every continent. The brand's boldness translates across cultures — making it one of the few Swiss manufactures with equally strong collector bases in Asia, the Middle East, Europe, and the Americas.
Crazy Hours — a mechanical patent
The Crazy Hours complication requires a programmed jump-hour mechanism that displays numbers out of sequence while maintaining accurate timekeeping. It is patented, unique to Franck Muller, and has generated more conversation about watches than almost any complication in the last 30 years.
Strong secondary market for complications
Franck Muller tourbillons, Aeternitas references, and early Cintrée Curvex complications hold strong secondary market values. Collectors who understand the brand's technical depth recognize pricing opportunities that casual buyers overlook.
Franck Muller FAQs
Why is Franck Muller called the "Master of Complications"?
Franck Muller spent the 1980s restoring some of the rarest antique pocket watches in private collections — pieces by Breguet, Patek, and other 18th-century masters. This gave him a deeper understanding of historical complications than any living watchmaker. He then invented new complications building on that knowledge, culminating in the Aeternitas Mega — certified by Guinness as the world's most complicated wristwatch with 36 complications. The title reflects documented achievement, not marketing.
How does the Crazy Hours watch tell time?
The hour markers are arranged out of sequence on the dial — 12, 9, 1, 8, 2, 10 and so on — but the hour hand still correctly indicates the time by jumping to the appropriate marker using a programmed mechanical cam system. A person who knows how to read it can tell the time instantly. Someone who doesn't sees apparent chaos — which is entirely the point.
What is the Cintrée Curvex case?
The Cintrée Curvex (meaning "curved" in French) is Franck Muller's signature case shape — a tonneau that curves simultaneously along the length, width, and depth of the case. Producing this shape requires custom tooling that no other manufacture possesses, which is why Franck Muller trademarked it. The result is a case that follows the wrist's curvature perfectly — one of the most comfortable wearing shapes in the history of watchmaking.
Do Franck Muller watches hold their value?
Franck Muller holds 60-75% of retail value across most references. Tourbillon models, Aeternitas editions, and Cintrée Curvex complications in precious metals command the strongest secondary market values. The brand's collector following in Asia, the Middle East, and Latin America provides deep global liquidity for well-maintained pieces.
How do I authenticate a Franck Muller?
We examine serial numbers, verify movement caliber against Franck Muller production records, assess case curvature and finishing quality, and inspect dial construction. The Cintrée Curvex case's distinctive three-axis curve is impossible to replicate accurately — but we still verify every component. Our 30+ years evaluating Swiss manufacture complications ensures no piece escapes thorough review.
