Is your Crazy Hours
the real deal?
The Franck Muller Crazy Hours is one of the most inventive complications in modern watchmaking. The hour hand jumps to seemingly random positions on the dial because the numerals are arranged in a non-sequential order, yet the watch always tells the correct time. This unique jumping hour mechanism, housed within the signature Cintrée Curvex tonneau case, makes the Crazy Hours both a conversation starter and a frequent target for counterfeiters. Here is how to tell if yours is genuine.
How to authenticate a Crazy Hours
Jumping Hour Complication Must Work Correctly
The defining feature of the Crazy Hours is the jumping hour mechanism. At the top of each hour, the hour hand should jump instantly and precisely to the next numeral in the sequence. The jump should be clean with no hesitation, stuttering, or slow drift. If the hour hand creeps between positions, does not jump at all, or jumps to the wrong numeral, the movement is not a genuine Crazy Hours caliber.
Non-Sequential Numeral Layout
The Crazy Hours dial arranges its numerals in a specific non-sequential order. Starting from 12 o'clock and moving clockwise, a genuine dial typically reads: 12, 7, 2, 9, 4, 11, 6, 1, 8, 3, 10, 5. This exact layout varies by reference but always follows a deliberate pattern. Counterfeits sometimes place numerals in random positions that do not correspond to any known Franck Muller reference, or they use the standard 1-through-12 layout with a non-functional jumping mechanism.
Cintrée Curvex Case Shape
The Crazy Hours is housed in the classic Cintrée Curvex tonneau case that curves in three dimensions to hug the wrist. The case should have a smooth, continuous curvature with no flat spots, perfectly polished surfaces, and precise transitions between polished and brushed finishes. Counterfeits often have cases that are too flat, have inconsistent curvature, or show visible machining marks along the case flanks and between the lugs.
Movement Finishing
Through the caseback, the Crazy Hours movement should display high-quality finishing including Geneva stripes on the bridges, properly beveled edges, blued or polished screws, and correct Franck Muller engravings. The jumping hour module adds complexity, so look for the additional springs and levers that drive the complication. A generic automatic movement without the jumping hour module is an immediate indicator of a counterfeit.
Dial Color and Texture
Crazy Hours dials come in a range of colors including silver, black, blue, and various lacquer finishes. Genuine dials have a rich, even color with a subtle sunburst or guilloché pattern that catches light beautifully. The oversized numerals should have consistent color, sharp edges, and proper depth whether they are applied or printed. Counterfeit dials often have flat, dull colors, uneven finishes, and numerals with fuzzy edges or inconsistent sizing.
Crown and Caseback
The crown should feature the Franck Muller logo or name, engraved or embossed with clean, sharp detail. It should operate smoothly with distinct positions for winding and time-setting. The caseback carries deep, precisely engraved reference numbers, serial numbers, material stamps, and "FRANCK MULLER GENEVE" text. On precious metal models, proper hallmarks for gold or platinum should be present and correctly struck.

Non-Functional Jumping Hour
The most critical test for a Crazy Hours is whether the jumping hour complication actually works. On many counterfeits, the hour hand simply sweeps continuously like a normal watch, or it hesitates and drifts slowly between positions rather than making a clean, instantaneous jump. Some fakes have the scrambled dial numerals but use a standard movement with no jumping mechanism at all.
Wrong Numeral Sequence
Every genuine Crazy Hours reference has a specific, documented numeral arrangement. If the numerals are placed in a random order that does not match any known Franck Muller reference, or if they follow the standard 1-through-12 sequential layout, the watch is counterfeit. Always verify the numeral positions against the official specification for the exact reference number.
Flat Tonneau Case
The Crazy Hours should be housed in a Cintrée Curvex case with compound curvature. Counterfeits frequently use a flat tonneau-shaped case that does not curve properly along the wrist. Hold the watch from the side and check that the case and crystal follow a smooth arc. A flat profile is a strong indicator of a counterfeit.
Poor Dial Quality and Numeral Finishing
On genuine Crazy Hours dials, every numeral is perfectly aligned with crisp edges, consistent color, and proper spacing. Counterfeit dials show blurry numeral edges, inconsistent sizing between numerals, color bleeding where the numerals meet the dial surface, and printing that smudges or rubs off. The "FRANCK MULLER" and "CRAZY HOURS" text should be razor-sharp under magnification.

Frequently asked questions
How does the Crazy Hours jumping hour complication work?
The Crazy Hours complication uses a specially designed movement module that causes the hour hand to jump to seemingly random positions on the dial. The numerals on the dial are arranged in a non-sequential order (for example, where 1 o'clock would normally be, you might find the numeral 7). The hour hand jumps to the correct numeral at the top of each hour, while the minute hand sweeps continuously and normally. So even though the numerals appear scrambled, the watch always displays the correct time. The jumping mechanism is purely mechanical, driven by a series of precisely calibrated springs and levers.
What is the correct numeral layout on a Crazy Hours dial?
On a genuine Franck Muller Crazy Hours, the numerals are arranged in a specific non-sequential pattern around the dial. Starting from the 12 o'clock position and moving clockwise, the sequence is typically: 12, 7, 2, 9, 4, 11, 6, 1, 8, 3, 10, 5. This means at 1 o'clock, the hour hand points to the numeral 7; at 2 o'clock, it jumps to the numeral 2; and so on. The exact sequence may vary slightly between different Crazy Hours references, but every genuine model follows a specific, intentional pattern. A counterfeit may have the numerals in the wrong positions or in a random arrangement that does not match any known Franck Muller reference.
How much does a Franck Muller Crazy Hours cost?
The retail price of a Franck Muller Crazy Hours varies significantly depending on the case material, size, and dial variant. Stainless steel models typically start around $12,000 to $18,000. Rose gold or white gold versions range from $25,000 to $50,000. Limited edition models, diamond-set versions, and special dial colors can command prices well above $50,000. On the pre-owned market, prices vary based on condition, box and papers, and the specific reference. The Crazy Hours' unique complication and collectibility help it retain value well compared to many other Franck Muller models.
