Choose Your Perfect Case : Stainless Steel or Titanium?

Personalize your Brellum Duobox TC Moonphase Chronometer by selecting the case material that best reflects your style. Choose between the timeless strength of stainless steel or the lightweight resilience of titanium, paired with a stainless steel bezel. Stainless steel offers a classic, enduring look, while titanium is 40% lighter and delivers modern durability — ideal for those who appreciate a contemporary, high-performance feel.

Whichever you choose, both options exemplify Brellum’s commitment to exceptional craftsmanship, offering outstanding quality and a refined aesthetic tailored to your preferences.

A Masterpiece of Complications and Precision

Beyond its elegant display of hours, minutes, seconds, and 12-hour chronograph, the Brellum Duobox TC Moonphase Chronometer is equipped with a suite of sophisticated complications. These include a triple calendar function with date, day, and month indications, a day/night indicator, and a beautifully rendered moon phase display at 6 o’clock.

Powered by a COSC-certified chronometer movement, this timepiece upholds the highest standards of accuracy and reliability. The Duobox TC Moonphase Chronometer is a harmonious blend of technical mastery and aesthetic refinement — a true collector’s piece for those who value fine Swiss watchmaking at its best.

A Brilliance of Texture and Craftsmanship

The Duobox LE captivates with a sophisticated interplay of polished and satin-brushed finishes, creating a refined case design that catches the light with every movement. This meticulous attention to texture enhances both the visual appeal and the tactile experience, striking the perfect balance between timeless elegance and enduring strength. Whether you opt for the robust stainless steel case or the ultra-lightweight titanium version, each offers a distinct personality — tailored to your individual style.

For optimal legibility, the watch features domed sapphire crystals with anti-reflective coatings on both the dial and caseback sides, ensuring clarity from every angle. Completing the ensemble is a handcrafted black leather strap, paired with a stainless steel deployment buckle — or a titanium buckle when matched with the titanium case. The result is a timepiece that not only stands out for its technical excellence but also offers exceptional comfort and a luxurious wearing experience.

A Guarantee of Precision and Exclusivity

At the heart of the Brellum Duobox TC Moonphase Chronometer lies the legendary Swiss Valjoux movement, visible through the exhibition case back in sapphire crystal. Expertly adorned with traditional watchmaking finishes — including Côtes de Genève, Perlage, and blued screws — the movement is further distinguished by a custom rotor inspired by the moon, individually numbered from 01/33 to 33/33, making each piece truly one of a kind.

Certified by the Contrôle Officiel Suisse des Chronomètres (COSC), each timepiece is delivered with its official chronometer certificate — a testament to Brellum’s unwavering commitment to precision, performance, and Swiss watchmaking excellence.
