Unveiled during the 2023 Geneva Watch Days, the new De Bethune DB28XP Kind of Blue watch unites the elegance of DB28XP and the timeless charm of DB28 Kind of Blue. Crafted from blued titanium, this lightweight, ultra-thin wristwatch is available in a limited edition of 25 pieces.
The deep and luminous shade of DB28XP Kind of Blue is achieved through the natural oxidation of the material, endowing a unique appearance for each piece. The emblematic Microlight dial in blued titanium reimagines and modernizes traditional guilloche decoration.
The manual-winding movement DB2115v12 is equipped with the De Bethune balance wheel, visible through the dial thanks to its opening at 6 o’clock. Made of titanium and fitted with small gray gold weights placed externally, it comes with remarkable inertia, reliability, and regulating quality.
Equipped with the renowned De Bethune hairspring, this tiny, extremely thin spring has been designed to keep its center of gravity precisely in the center by using a flat curve fixed on the outside of the hairspring.
Variations in the thickness of the blade contribute to nearly perfect concentric development. Among the numerous advantages are: reduced height, improved adjustment of concentricity quality, finer balance wheel adjustment, eliminating the need for pins, and the curved shape even acts as a shock absorber in case of impact.
Thanks to various enhancements, the Calibre DB2115v12 comes with an increased power reserve of 6 days.
The sapphire crystal case-back offers the view of its power reserve indicator as well as the complexity and beauty of each component.
Equally visible and geometrically positioned relative to the caliber’s mainplate, the assembly is protected by the exclusive triple shock-absorbing system.
The DB28XP Kind of Blue has a polished blue-tinged grade 5 titanium case with a curved microlight caseband, mounted on mobile cradles that adapt to the size and various movements of the wrist. The Microlight finish of the mainplate is echoed on the sides, extending to the outer edge of the caseband.
The De Bethune DB28XP Kind of Blue watch comes with an alligator strap and a titanium buckle.
