DB25 Perpetual Sky Captures Time, Stars, and Innovation

The DB25 Perpetual Sky is a horological masterstroke from De Bethune, unveiled at Dubai Watch Week and crafted with breathtaking precision. Designed for those with a discerning eye for haute horlogerie, this 40mm titanium marvel compresses a universe of craftsmanship into a case fit for slender wrists—without sacrificing the brand’s signature boldness. The DB25 Perpetual Sky transforms celestial poetry into functional mechanics, offering a perpetual calendar framed by a stunning rendition of the Milky Way and a patented spherical moonphase unlike anything else on the market.

From its polished titanium shell to its thermal-blued, star-studded dial, the DB25 Perpetual Sky is more than a timepiece—it’s a wearable observatory. The meticulous downsizing of De Bethune’s previous 44mm model required a complete reengineering of the case and movement structure, ensuring that legibility, comfort, and visual depth remain uncompromised. The lugs are hollowed for seamless integration, allowing the timepiece to rest elegantly on the wrist while maintaining a sleek 11.3mm profile.

DB25 Perpetual Sky: Technical Genius Beneath the Surface

Inside the DB25 Perpetual Sky beats the hand-wound DB2005 V3 calibre—a testament to De Bethune’s unparalleled innovation. Comprised of 339 meticulously finished components, this movement boasts a five-day power reserve thanks to a self-regulating double barrel. De Bethune’s technical arsenal is fully deployed here: a titanium balance wheel with white gold inserts (optimized for thermal fluctuations), a silicon escape wheel, the brand’s proprietary flat-curve balance spring, and the triple pare-chute shock-absorbing system.

At 12 o’clock, a palladium and blued steel moon phase sphere—accurate to one lunar day every 122 years—sits beside a gold disc that marks the leap-year cycle. Subdials positioned at 3, 6, and 9 o’clock display the month, date, and day, respectively, all surrounded by hand-curved, mirror-polished yellow gold hands that sweep over a silver-toned Roman numeral ring. The entire mechanism is visible through a sapphire crystal caseback, inviting collectors and aficionados to admire the inner cosmos of this intricate machine.

The blued titanium dial is studded with white gold stars, individually set into laser-perforated microholes. The Milky Way appears through laser micro-engraving, brought to life with painstakingly inlaid 24-carat gold leaf. Each DB25 Perpetual Sky dial can be personalized to reflect a specific sky at a particular time and place, making each watch as unique as its owner’s story.

DB25 Perpetual Sky: Exclusivity, Elegance, and Availability

Production of the DB25 Perpetual Sky is strictly limited by the human scale of De Bethune’s Haute Horlogerie workshop in L’Auberson. Each timepiece is assembled, tested, and finished by hand—crafted not on an assembly line, but at a master watchmaker’s bench. The watch is paired with a supple alligator strap and a polished titanium pin buckle, completing its refined silhouette.

Pricing is available upon request through De Bethune’s authorized retailers and boutiques, underscoring its exclusive nature. For those looking to acquire one of the most technically advanced and artistically expressive perpetual calendars ever made, the DB25 Perpetual Sky stands as the pinnacle.
