Where Tradition Meets Innovation: The Art of Time Redefined

De Bethune's Distinctive Identity and the Genesis of the DB25xs

De Bethune stands out in the world of independent horology, instantly recognizable through its signature design elements. Co-founder and master watchmaker Denis Flageollet is the visionary behind these aesthetics, which include heat-treated titanium components and intricate random guilloché patterns. While the futuristic DB28 line serves as a flagship, the classical DB25 collection, first introduced in 2007, offers a contrasting appeal. This collection is characterized by its round, drum-shaped cases and distinctive hollowed bullet-shaped lugs. The DB25xs, an 'extra small' iteration launched in 2025, has been chosen for this latest release, featuring an exquisite yellow heat-treated titanium dial adorned with a random guilloché pattern that beautifully mimics the undulating ripples of sand dunes under a gentle breeze.

The Accidental Discovery of Chromatic Oxidation

The vibrant, signature colors seen on De Bethune's titanium components are a result of what the brand describes as the 'art of chromatic oxidation.' This remarkable effect was discovered serendipitously in the laboratory by Flageollet. He was originally attempting to stabilize a titanium balance wheel using the same treatment typically applied to blued steel. However, as the temperature increased, the titanium surface underwent a fascinating transformation, changing colors from a warm amber at lower temperatures, progressing to a rich purple, and finally achieving an intense electric blue at the highest temperatures.

Reimagining Guilloché: A Contemporary Twist on a Classic Art

Flageollet's passion for classical watchmaking, coupled with his innovative use of aerospace-grade materials, led him to reinterpret the venerable art of guilloché. The brand's distinctive random guilloché pattern is a modern take on this traditional technique, breaking away from the rigid geometric precision often associated with classical designs. De Bethune's approach creates a seemingly haphazard motif of irregular, undulating horizontal lines that ripple across the dial. This unique hand-guilloché technique is not limited to conventional materials; it is also applied to hard-grade metals like titanium and even meteorite, showcasing the brand's commitment to pushing creative and technical boundaries.

The DB25xs Sand Winds: A Dial Inspired by Nature's Artistry

The DB25 collection has historically been celebrated for its celestial Starry Varius dials. The new DB25xs Sand Winds continues this legacy with a yellow heat-oxidized titanium dial, meticulously decorated with a random guilloché pattern. This design ingeniously captures the essence of sand dunes, with asymmetric undulations that add remarkable depth and dynamically interact with ambient light. Further enhancing this scenic tableau are hand-applied spherical white gold stars, subtly scattered across the dial. The rounded titanium chapter ring features elegant Arabic numerals and polished titanium spherical markers. In keeping with its classic spirit, the hand-polished titanium Breguet-style hands boast open tips and are heat-treated, along with the spherical markers, to achieve a warm brown hue, complementing the dial's overall aesthetic.

Precision Engineering: The Heart of the DB25xs Sand Winds

The 40.6mm titanium case of the DB25xs Sand Winds features an exceptionally slender profile of just 8.8mm, polished to perfection. Its compact dimensions, along with the brand's signature openworked tapering lugs with bullet-shaped tips, and the inherent lightness of titanium, ensure an exceptionally comfortable fit on the wrist. Equipped with anti-glare sapphire crystals on both the front and back, the reverse side offers a mesmerizing view of the in-house calibre DB2005. This manual-winding movement operates at a frequency of 4Hz and boasts an impressive six-day power reserve, thanks to its patented self-regulating twin barrel system. Other notable features include a heat-blued titanium balance wheel with white gold inserts, a patented hairspring with a flat terminal curve, a silicon escape wheel, and a sophisticated para-chute shock-absorption system. The movement's aesthetics are dominated by a large, delta-shaped barrel bridge adorned with elegant Côtes de Bethune stripes and a thermally blued central brace, providing glimpses of the solarized barrels and the mirror-polished balance bridge.

Refined Finish and Availability

The DB25xs Sand Winds is elegantly presented on a brown alligator leather strap, complete with an alligator lining and a polished titanium pin buckle. This exquisite timepiece is a permanent addition to De Bethune's collection. Further details can be found on debethune.ch.
