Back to collection

Reliability, technical excellence, and refinement.
A diving watch designed for optimal legibility of time and immersion duration, both day and night. Introduced as a continuation of the sport line started in 2019 with the DB28GS Grand Bleu, the DB28GS Swordfish carries the same bold, elegant spirit with a new bi-chromatic interpretation of De Bethune blue and black. It reflects the Maison’s commitment to performance, innovation, and comfort—on land and underwater.
