Description

This UNIQUE DB28GS has a yellow titanium case, purple titanium lugs, and yellow bridges. Timely offering since De Bethune just launched the Purple Rain, featuring Titanium, heated to a purple color - this piece was ahead of it's time!

The GS stands for Grand Sport, De Bethune's first-ever venture into the world of a Haute Horology sports watch back in 2015.

The DB28GS follows the De Bethune tradition of innovation and pushing the limits of what can be done in watchmaking. Built with a full grade 5 titanium finished by hand, with an imposing 44mm case diameter, which is coupled with our signature floating lugs also in grade 5 titanium. More weight saving is taken by the addition of the natural rubber strap featuring a microlight motif, a first among the brand’s collections, which also contributes to making it extremely pleasant to wear, as wearer comfort is something we have always strived for.

The DB28GS might have sport in mind with the design but the finishing is still 100% De Bethune quality. Hand-crafted refined finishes, which were performed in our workshops at L’Auberson, like the microlight decoration of the bridges and main-plate, the flat polishing of the deltoid-shaped bridge, or the deep azure shade of the hands achieved using the ancestral flame-blueing technique.

Inside the GS is the calibre DB2115. 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. A titanium balance wheel with a white gold insert 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 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. As a sports watch the DB28GS can also withstand three full leagues under the sea with a water resistance of 10 ATM.
