Castellan Équation du Temps 40

Shows the difference between clock time and solar time.

The sun does not peak at noon every day; in February it is about 14 minutes late, in November 16 minutes early. A second minute hand with a gold sun shows this true solar time, driven by a kidney-shaped cam that turns once a year.

Castellan Extraplat 3.9

One of the thinnest hand-wound watches: movement 2.1 mm, watch 5.2 mm.

The 3.9 in the name is the distance in millimetres between the crystal and caseback over the movement. You barely feel it on the wrist. Because the parts are so thin, it does not take knocks during sport.

Collection: Extraplat
Price: €36,000–€52,000
Versions: 18k white gold and Platinum 950

Castellan Flying Tourbillon Skeleton

Skeletonised watch with a flying tourbillon and no upper bridge.

The tourbillon turns once a minute and seems to float because it is held only from below. Almost all material between the parts is sawn away and bevelled by hand.

Castellan Joaillerie 33

Ultra-thin jewellery watch with diamond bezel and mother-of-pearl.

The thin Extraplat movement in a 33 mm case whose bezel is set with 60 brilliant-cut diamonds. The stones are set so closely that no metal shows between them.

Price: €58,000
Versions: 18k white gold and 18k rose gold

Castellan Petite Sonnerie 42

Watch that strikes every hour and quarter as it passes.

Like a church tower on the wrist: on every hour it strikes the hours, on every quarter the quarters, and on request the minutes. A switch silences it for concerts and meetings. Five pieces, delivery about two years.

Castellan Quantième Perpétuel Chronographe 41

Perpetual calendar and chronograph in one hand-wound movement.

Two great complications in one case: the calendar knows month lengths and leap years until 2100, the column-wheel chronograph times up to 30 minutes. The dial still stays calm because calendar and chronograph share the subdials.

Collection: Quantième
Price: €238,000–€265,000
Versions: Platinum 950 and 18k rose gold

Castellan Rattrapante 41

Split-seconds chronograph with two column wheels.

Two column wheels control the chronograph and split hand separately, so every press feels equally smooth. The pulsometer scale recalls the doctors such watches were once built for.

Price: €198,000

Castellan Répétition Minutes 41

Minute repeater that chimes the time on two gongs.

A slide on the left of the case chimes hours, quarters and minutes on two gongs. Tuning the sound takes longer in the workshop than assembly. Only ten pieces.

Price: €420,000

Castellan Seconde Morte 39

Mechanical watch whose seconds jump like a quartz.

The seconds hand moves one step per second instead of six to eight; a small extra wheel stores energy and releases it once a second. Look closely and the beat feels calmer than a quartz.

Price: €72,000

Castellan Squelette Extraplat 40

Ultra-thin skeleton watch at 6.2 mm, almost without a dial.

A movement 2.1 mm high with barely any material left after skeletonising. Every edge is bevelled by hand; under a loupe there is no trace of a tool. About six a year.

Collection: Extraplat
Price: €148,000–€168,000
Versions: Platinum 950 and 18k rose gold

Castellan Tourbillon Volant 41

Flying tourbillon without an upper bridge, floating freely at six.

The cage is held only from below, so it seems to float above the enamel dial. It turns once a minute, averaging out rate errors caused by gravity.

Category: Watches
Collection: Tourbillon
Price: €245,000–€285,000
Versions: 18k white gold and Platinum 950, 10 pieces

Castellan Ultra-Thin Perpetual Calendar

Perpetual calendar with moon phase only 8.3 mm high.

The calendar knows month lengths and leap years until 2100 and needs no correction while the watch runs. If it stops, the workshop resets it during service.
