De Bethune is revisiting its classics and reasserting its identity codes through the DB28 collection, a strongly identifiable timepiece endowed with the signature House style features and conveying its resolutely avant-garde vision of the watchmaking art. The wearer comfort of the DB28 stems from the surprising lightness, and to the presence of “floating lugs”, a patented system that easily adjusts to the size of the wrist and its various movements.
