Launched in 2010, the DB28 is most likely the timepiece that best exemplifies De Bethune's technical and design prowess, and it has become the brand's most recognizable model over time. The following year, at the Grand Prix Horlogerie de Genève, this model won the prestigious Aiguille d'Or award as best watch of the year. Denis Flageollet – the brand's co-founder and master watchmaker – spent decades restoring pieces made by the great masters of the 18th and 19th centuries, and he used his incredible knowledge of historical watchmaking to invent 21st-century watches like no other, as he puts it: "the tradition of watchmaking is innovation".

The present DB28 case is made of titanium and features the brand’s signature titanium spring-loaded floating lug system, enabling the watch to adapt to the wrist for ease of wear. The DB28 has a decidedly modern look; there is no dial since the top movement plate, which is rhodium plated and adorned with Geneva waves, is visible, as are the balance, triple parachute shock absorber, and part of the mainsprings. The 3D moonphase indication at the bottom of the dial, a wind performance indication between 2 and 3 o'clock, and a 6-day power reserve indicator on the case back are all obvious De Bethune distinctive elements.

The present DB28 further features the brand’s signature blued titanium lugs. To achieve such a result, an intense process of thermal oxidation on the surface of the material must be achieved by heating the alloy at a high temperature. The oxidation process of titanium goes through various stages and displays various colors in each stage, indicating that extreme precision and control are the utmost important asset to generate consistency.
