DB28 GS Swordfish is a diving watch in a 44mm zirconium and Grade 5 titanium case that guarantees, optimal legibility of the time and immersion duration. Designed to perform under challenging conditions, with reduced visibility, both day and night. The immersion time is read with a bezel that rotates the watch’s sapphire crystal in its unidirectional movement. The DB28 GS Swordfish displays the minute track on the sapphire glass itself.

In addition to the luminescent-tipped hands, the DB28GS Swordfish is equipped with De Bethune’s manual lighting system, which diffuses white light from the four corners of the dial (3, 6, 9, 12 o’clock) to illuminate the movement from the inside. This mechanical system functions without electronics or batteries. Activated by a push-button at 6 o’clock, which triggers a small gear driven by the dual barrel. This gear, through a miniature dynamo, provides the energy necessary to light the watch without affecting the movement’s operation. 

The DB28 GS Swordfish comfort is ensured by the positioning of the crown at 12 o’clock. Featuring the patented mobile cradle system, which adapts to the size and movement of the wrist. Enhanced by a DLC coating (Diamond-Like Carbon) that adheres perfectly to the ultra-hardened stainless steel of the cradles, ensuring resistance to shocks . The DB28 GS Swordfish cradles stand out with blued Grade 5 titanium inserts. The natural rubber strap also contributes to the watch’s comfortable wear.

The DB28GS Swordfish boasts water resistance to a depth of 105 meters. Its DB2080 movement is equipped with a double barrel self-regulating system that provides a 5-day power reserve,  indicated between 9 and 10 o’clock. The presence of a titanium/grey gold balance wheel, designed to adapt to temperature variations, along with a flat terminal curve hairspring, ensures an optimal mass/inertia ratio for an ideal frequency of 28,800 vibrations per hour.  A titanium bridge, equipped with shock absorbers at both ends (ruby + blade spring) and a central damper, ensures precise position stability of the balance wheel, even during violent impacts.
