The DBS marked the beginning of a long thought process at De Bethune on how to ensure an ideally comfortable fit: the pivoting plate attachment at 12 o'Clock was the forerunner of the floating lugs with their patented spring-type system. Ten years later, an anniversary edition of ten pieces in white gold is brought to life by the in-house developed, high-frequency, 30-second tourbillon. Deltoid-shaped bridges, Côtes De Bethune decoration and steel blued using the centuries-old flame-blueing technique are among the characteristics that have grown to become signatures of the brand. A remarkable compendium of technical and aesthetic innovations that are unique to De Bethune.
