De Bethune DB28 GS
The DB28 GS expresses a bold character revealed through both its aesthetic and technical attributes.
The DB28 GS fully complies with the strict rule of wearer comfort that De Bethune applies to its models, and particularly those in the DB28 collection. It owes this exceptional comfort to a combination between the lightness of the titanium case, the softness of its hand-polished finish, the 12 o’clock crown position, a natural rubber strap featuring a microlight motif, and above all the patented floating lugs system that adapts to wrist size and movements.
The timepiece has fully benefited from the special attention lavished on refined hand-crafted finishes performed in the workshops at L’Auberson, such as the microlight decoration of the bridges and mainplate, the flat polishing of the deltoid-shaped bridge, or the deep azure shade of the hands achieved using the ancestral flame-blueing technique.
The DB28 GS is water resistant to 100m. Its DB2115 hand-wound 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.
The presence of the silicon/white gold balance wheel and balance-spring with flat terminal curve ensures the ideal inertia-mass ratio for an optimal frequency of 28,800 vph suited to wristwatches.
The work done on the regulating organ follows well-known physical laws. The patents for the curve of the balance-spring as well as the annular balance, featuring maximum inertia and minimal weight, composed of a disc made of openworked silicon (a light material in the centre) and white gold (a heavy material on the exterior), all present significant technical advances contributing to the performance and precision of this calibre.
The watch also undergoes a number of reliability and shock-resistance tests, which it passes with flying colours notably because of its triple pare-chute shock-absorbing system that protects the heart of its movement by a titanium bridge held by a spring system. Three jewels connect the various elements, serving not only to absorb shocks but also to secure the bridge in case of abrupt displacements.
De Bethune embraces the wealth of the watchmaking knowhow of the past in order to design the watches of the future. This combination results in timepieces with all the attributes and technical expertise of Fine Watchmaking, whilst at the same time remaining free from traditional constraints.Find out more
