David Candaux DC6 Piece Unique

We had the pleasure of speaking with David Candaux at Dubai Watch Week last year about his latest release, the DC12 Maverik. Born and raised in the Vallée de Joux, the master watchmaker imagines, develops, and finishes his creations entirely by hand in his atelier at Le Solliat. Over the last decade, Candaux has earned a devoted following among independent collectors for his highly technical, forward-looking watches that nonetheless remain deeply rooted in traditional chronometry. Today, we present for the first time a pre-loved DC6 Pièce Unique in an ultra-lightweight titanium case.

The DC6 draws inspiration from two seemingly disparate historical timepieces: hunter pocket watches, with their exposed guillochage cases, and navigational instruments prized for their precision and durability. What initially appears to be an unlikely mashup resolves into a cohesive and striking aesthetic. The bassinet-shaped case with its smoothly curved lugs immediately sets the watch apart, signaling that this is no conventional round sports watch or classical dress piece.

At first glance, it is easy to overlook that the sapphire crystal does not span the entire bezel. Instead, it covers only the dial and tourbillon apertures, leaving the surrounding surface exposed. This detail directly references hunter cases, where engraved or guilloché metal served a functional role by improving grip. On the DC6, this exposed surface is finished with Candaux’s proprietary guillochage pattern, Pointe du Risoux, developed to echo the textures of the fir trees that surround his atelier. Both tactile and visual, it invites interaction rather than passive admiration.

Viewed through this lens, the DC6 reads less as an eccentric design statement and more as a contemporary reinterpretation of the half-hunter form. Historically, these watches were built for demanding environments on land and at sea, prioritizing protection of the movement and legibility under stress. Candaux draws from antique captain’s watches and marine instruments, where metal-covered dials reveal information only through carefully placed portholes. Despite its complexity, the DC6 retains this sense of purpose and restraint.

The dial architecture reinforces this idea. Time is displayed through two convex sapphire portholes set into the guilloché front: hours and minutes on a spherical micro-dial to the right, and a fully visible flying tourbillon to the left, providing running seconds via a blued index on the cage. A separate sapphire arch at the top reveals the power reserve. The entire assembly is subtly inclined, higher at 12 o’clock and lower toward 6, enhancing legibility and giving the watch a distinctive forward-leaning posture. A patented retractable crown at 6 o’clock preserves the integrity of the case while underscoring Candaux’s unconventional approach to engineering.

At the heart of the DC6 is Candaux’s inclined bi-plan flying tourbillon. The 60-second cage is set at three degrees, while the balance within is inclined by an additional 30 degrees. This configuration ensures constant variation in the regulating organ’s position as the watch moves through the angles of daily wear, addressing gravitational challenges that traditional pocket-watch tourbillons were never designed to encounter. A Breguet overcoil with a Phillips terminal curve reflects Candaux’s adherence to classical chronometric principles.

The in-house Caliber 1740 and the case are both crafted from grade-5 titanium, a material Candaux favors for its strength-to-weight ratio and long-term stability, despite the significant challenges it presents in machining and finishing. The inclined movement architecture creates a cascading bridge layout that amplifies light reflections and highlights Candaux’s proprietary Côtes du Solliat finishing, while all internal angles are executed with traditional Vallée de Joux anglage. Specific to this pièce unique is a diamond mounted to a gold plate at 6 o’clock on the movement, as well as the plates’ finish with its intense, dragonscale-like texture.

Produced in extremely small numbers, the DC6 Piece UniqueTitanium “1740” was originally offered in three colorways (orange, blue, and red) each limited to eight pieces and fitted with a Velcro strap and titanium buckle. As a pre-loved example, it offers a rare opportunity to experience David Candaux’s singular vision of contemporary haute horlogerie: one that bridges navigational history, radical engineering, and the living traditions of the Vallée de Joux.
