De Bethune presents the DB28 Yellow Tones
With complete mastery of the art of thermal oxidation of metals, De Bethune continues to explore all the colour shades resulting from the heat released by the chemical reactions of heat-treated steel and titanium.
After working with the blue color for more than 15 years, Denis Flageollet now explores a warm colour.
To create its own fiery, radical, magnetic yellow, De Bethune applies its famous technique of gently oxidising grade 5 titanium to tint its surface naturally. This ritual conjures an extraordinary, rare and uniform fire yellow.
This oxydation is applied to the case components and to most of the movement’s components. Each element is thus individually examined to ensure the process is properly calibrated to suit shape and mass.
The iconic DB28 features the two new floating lugs unveiled this year. All beauty and refinement, a timepiece that presents a hand-wound mechanical calibre, fully visible and incorporating the Maison’s latest innovations:
• The patented spherical moon phase is located at 6 o'clock. Made of steel and palladium, it is accurate to within one lunar day every 122 years.
• Aerodynamics, optimised efficiency, reliability, regulating quality, thermo-compensation, anti-magnetism... the high-performance escapement features a titanium balance wheel with white gold weights and a patented flat terminal curve balance spring, ensuring an ideal mass-inertia ratio for the optimal frequency of 28,800 vph suitable for wristwatches
• The calibre also comes equipped with the triple “pare-choc” shock absorption system. De Bethune was not only the first to design a bridge held symmetrically on both sides to perfectly maintain the balance wheel in position, but also to integrate two shock absorbers at each end, in addition to the shock absorber of the balance wheel itself.
