The bold nature of the DB28 GS is revealed through both its aesthetic and its technical attributes. It fully complies with the strict rule of wearer comfort that De Bethune applies to all 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 handpolished finish, the 12 o’clock crown position, and above all the presence of the patented floating lugs system that adapts to wrist size and movements. A natural rubber strap featuring a microlight motif, a first in the brand’s collections, also contributes to making it extremely pleasant to wear.
This model has fully benefited from the special attention lavished on refined hand-crafted finishes in the workshops at L’Auberson, such as the microlight decoration of the bridges and mainplate, the flat polishing of the deltoid-shaped bridge, and the deep azure shade of the hands achieved using the ancestral flame-blueing technique.
It also meets the high demands and reliability standards imposed by the De Bethune Technical Department on its inhouse calibres, notably by equipping them with the innovations and patented inventions that are the fruit of 13 years’ research by the engineers in La Chaux.
The DB28 GS proudly displays unimpeachable 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.
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.
