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.
I can source any watch, new or used, even very hard-to-get. I chose these examples to guide you.
Cintrée Curvex · 39 × 55mm · 8880 CC QP B
From about $16,000
Two arcs show the day of the week on the left and the date on the right, and each hand returns to the start when the week or month ends. The calendar shows the right date at the end of every month, leap years included, until 2100, and the watch also has a chronograph and a moon phase.
Aeternitas · 42 × 61mm · Automatic · 8888 T QPS
About $128,000 to $138,000 at auction
Franck Muller launched the Aeternitas 4 in 2006. Its calendar shows the year in a window below the center, and a small dial shows the equation of time, the gap between clock time and sundial time. Two more small dials show extra time zones, and a tourbillon turns at 6.
Vanguard · 44 × 53.7mm · Manual wind · V 45 AERO REV 3 SQT MVT5N NR LTD 5N
Around $600,000
Three nested cages turn the tourbillon on three different axes, and windows on four sides of the case show the movement from the sides as well as the front. One full winding keeps the watch going for 10 days, and Franck Muller makes 8 of each version.
Vanguard · 46 × 55.9mm · Manual wind · V 50 L RM T SQT (NR)
About $273,000 at launch in 2018
A slide on the left side of the case starts the chime, and the watch strikes the hours, quarter hours, and minutes. Franck Muller cut the dial away to show the whole movement, with the tourbillon turning at 6.
Vanguard Racing · 44 × 53.7mm · V 45 VEGAS SQT RCG CARBON ERTap to see the back
$45,000 at launch in 2023
Franck Muller made 23 of these for the 2023 Las Vegas Grand Prix and sold them only through Neiman Marcus. When you press the button on the crown, a center hand spins around the roulette wheel and stops on a random number.
Cintrée Curvex · 34 × 47mm · Automatic · 6850 VEGAS D
From about $25,000
One of my favorite watches (though I don't prefer the diamonds). You push the little button on the crown and the curly hand whirls round and round quickly, until you let go, and it stops randomly on one of the slots. It really works! It comes in all metals and many dials and diamond options. SJX calls the Vegas a bestseller for Franck Muller and says casino watches from other brands followed it.
Cintrée Curvex · 37 × 52.4mm · Manual wind · 7885 RM T CH
About $409,000 at launch in 2025
When you see "curvex," that means the case is curved to fit your wrist better than a flat back. It matters on a longer watch like this. On a Crazy Hours dial the numerals are out of order, and at each new hour the hour hand jumps to the matching numeral. In this version, Franck Muller added a tourbillon at 6 and a minute repeater, which chimes the time on demand. It came out in 2025, twenty years after the first Crazy Hours Tourbillon. At under $500,000, it's a very good value.
Cintrée Curvex · 39 × 55mm · Automatic · 8880 GD
About $11,000 to $19,000 at auction
One of my favorite watches, a classic. A hand sweeps an arc of weekdays across the upper half of the dial and returns to Monday when the week ends. A large date fills a window below 12, and the small dial at 6 shows the month along with the running seconds. Franck Muller made it around 2006.
Vanguard · 44 × 53.7mm · Manual wind · V 45 T GR CS SQT BR (NR)
From about $152,000
Franck Muller built the Gravity around an oval tourbillon cage 21.2mm across, with the balance wheel set off center inside it. On this black skeleton version, Franck Muller colored the cage, hands, and markers blue.
Vanguard · 44 × 53.7mm · Manual wind · V 45 T GR CS SQT (NR) 5N
$130,000 to $160,000
Franck Muller made this case in rose gold and colored the openwork frame inside it to match. The oversized oval tourbillon cage turns once a minute, in full view through the open dial.
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.
