De Bethune is firmly in the limelight at the SIHH 2018 and has just unveiled the unusual architecture of its movement through an exceptional timepiece named DB28 Steel Wheels, issued in a 25-piece limited edition.
Crafted from titanium and dedicated to transparency and light, the DB28 Steel Wheels features a sophisticated and particularly light movement structure thanks to the cut-out version of its central delta-shaped bridge. Its self-regulating twin barrels ensures a six-day power reserve. The movement is equipped with a De Bethune balance-spring with flat terminal curve, a silicon escape-wheel, a triple pare-chute shock-absorbing system, as well as a new even more high-performance titanium balance-wheel with white gold inlays.
The ratcheted chapter ring inspired by gear-wheel toothing surrounds 12 polished spheres marking the hours and adding to the overall volume of the mechanism. The new hours hand, made of sapphire rimmed by blued steel, reveals the heart of the movement. Each detail of the anatomy of this new creation is thus open to view. The Manufacture’s signature spherical moon composed of palladium and blued steel sets the perfect finishing touch to this magnificent vision. Appearing against its night-sky backdrop at 6 o’clock, it spins on its axis with such precision that it will take 122 years to accumulate a one-day discrepancy.
Like all the models in this collection, the DB28 Steel Wheels surprises observers by the light feel of its case, entirely crafted in titanium, and by the presence of De Bethune’s patented floating-lug system adjusting to wrist size and movements.
