De Bethune has devoted considerable research into natural blue because the brand considers this color to be symbolically related to the concept of infinity and harmony. Therefore, De Bethune has dedicated to the DB 28 Kind of Blue Z.
Blue is also associated with the notion of plenitude: within and beyond itself, and as far as this unfathomable infinity that is the universe, the source of life. So blue becomes a vector that subtly connects mankind with his physical and his spiritual environment. Seen in the context of artistic expression, the concept of blue approaches the magic of music, which is the inspiration for the name given to these creations.
To create its own blue, De Bethune relied exclusively on a traditional technique, and all the parts in titanium and steel used in Kind of Blue Z were treated in this manner. It consists of heating the material to color its surface through oxidation and to modify its physical properties in the process. Since its invention at the beginning of the 16th century, the technique has been used by watchmakers to give a new luster to watch parts without altering their finishings.
An iconic De Bethune model, the DB28 presents a case made of polished grade 5 titanium, mounted on two floating lugs to ensure superior wearing comfort. On the inside, the mechanical caliber with manual winding is fully visible and integrates several fundamental technical inventions. The patented spherical moon-phase is positioned at 6 o’clock. Made of steel and palladium, it offers precision that varies by only one lunar day every 122 years. At the heart of the watch, the high-performance escapement developed by De Bethune presents a silicon annular balance, encircled by a white gold ring and a balance-spring with a flat terminal curve that is exclusive to De Bethune. It is protected by a triple pare-chute shock-absorbing system. Power is accumulated and distributed through two self-regulating barrels, also developed by De Bethune. An indicator needle positioned between 2 and 3 o’clock indicates the level of torque that has been built up. The power reserve indicator can be read on the back of the plate, which is decorated with special concentric graining. All the finishes are done by hand with a motion work bridge in polished titanium, bridges with “Côtes De Bethune” decoration and rose-work grinding on the barrel ratchets. The hours are indicated by skeleton hands on arrow pointers made of polished steel.
