Franck Muller · Cintrée Curvex · Crazy Hours · Iron Croco · steel · on Amazon
Scrambled numerals on crocodile skin.
Franck Muller’s two most recognisable ideas, on one watch. Crazy Hours scatters the twelve numerals out of order and gives the hour hand a jump once an hour to the next one, so the watch reads only if you know the trick. Iron Croco embosses a crocodile-scale relief into every surface of the steel Cintrée Curvex case and across the dial, so the watch reads as one hide from crystal to strap. This one wears the white alligator strap. Automatic, calibre FM 2800 CH. Sold on Amazon by an independent dealer.

Two signatures at once
Crazy Hours came first, in 2003: a dial where each numeral sits five positions clockwise from the last, so the sequence looks random and is not, and an hour hand that is held still for sixty minutes and released to jump to the next number. The minute hand is untouched. The Croco cases came later, a crocodile-scale pattern pressed into the bezel, flanks, lugs and dial of the Cintrée Curvex; Iron Croco is the steel version, Gold Croco the gold.
Put together, the watch is entirely texture and numerals: no printed minute track to speak of, no seconds hand, no date, just the relief and the twelve scattered figures with a black outline so they stand off the silver. The white alligator strap is the dealer’s chosen configuration and the reason the watch reads as summer rather than boardroom.

Reading the listing
The listing is a title and a dealer code: Casablanca Iron Croco Dial Crazy Hour White Strap Swiss Automatic, 8880CHIRCRACWH. There are no spec rows and no description, so there is nothing to contradict, and the photograph shows the watch the title describes: steel croco case, croco dial reading Iron Croco, scrambled numerals, white strap. The case dimensions, calibre and reserve here are Franck Muller’s published figures for the 8880 Crazy Hours, not the dealer’s. Franck Muller sells this design under the Cintrée Curvex name; Casablanca in the title is the dealer’s wording.
Whether the watch is new with Franck Muller’s warranty is not stated in the rows we read; ask, and ask for the box and papers. Every figure here comes from the listing and from Franck Muller’s published description, not from handling the watch.

Buying it on Amazon
This is a regular Amazon listing from an independent dealer, Luxor Watches on the day we read it, with Amazon’s 30-day return window; it is not a Luxury Stores pre-owned unit. The second button opens the live search for Iron Croco Crazy Hours in case this one has sold.
Crazy Hours models have resold for well under new and close to what pre-owned buyers paid, sometimes more, sometimes less; that is a pattern, not a promise, and nothing here is investment advice.

Verdict
A steel Iron Croco Crazy Hours on a white strap, on Amazon from a dealer: Franck Muller’s jumping-hour dial on its crocodile-relief case, for someone who wants the brand at full strength in one watch.
Strengths
- The Crazy Hours jumping-hour mechanism, a real complication with a joke in it
- Crocodile relief across case and dial; nothing else looks like it
- Steel, under 40mm wide; the smaller Franck Muller case on this page
- Amazon’s return window on a dealer listing
Trade-offs
- Takes a beat to read; that is the point
- White strap shows wear; keep a spare
- Condition and warranty not stated; ask
- 30 metres; a dress watch
Buy it if
Someone who already has the plain watches and wants the one that makes people ask twice.
Skip it if
You want to read the time at a glance, or a quiet dial.
FAQ
The minute hand runs normally. The hour hand stays on one numeral for the hour, then jumps to the next number in sequence, wherever it sits on the dial. Read the numeral the hour hand points to, then the minutes.
