DB28

Grand Sport

Reference: DB28GSBV1AN

The DB28GS expresses a bold character revealed through both its aesthetic and technical attributes. It fully complies with the strict rule of wearer comfort that De Bethune applies to its models, and particularly those in the DB28 collection. The DB28GS proudly displays impeccable water resistance to depths corresponding to three full leagues under the sea. Its DB2115 calibre is equipped with a self-regulating twin barrel ensuring a 6-day power reserve – a performance that can be tracked by means of a blue indicator at 3 o’clock.
