De Bethune DB28

The DB 28 model features all the characters of the existing creations of the De Bethune Manufacture. Its specially designed case is adorned with its famous crown at 12 o’clock like those of pocket watches. A special spherical moon-phase indicator is located at 6 o’clock.

This model can be placed in mid way between the DBS timepiece and the model developed exclusively by De Bethune for Only Watch 2009.

The dial serves as a window onto the movement, revealing the refined craftsmanship of the hand-executed finishes developed in the De Bethune workshops. The delta-shaped polished steel mainplate and De Bethune “stripes” are combined with a blue chapter ring to ensure optimal readability. The shimmering effects of the light playing across the polished and matt surfaces create a unique show visible exclusively on the wrists of a privileged few.

The case is entirely made in titanium, so it is light weight and to the presence of “floating lugs”, a patented system that easily adjusts to the size of the wrist and its various movements.

The DB28 is powered by Calibre DB2115 which is equipped with the latest technological innovations developed and produced within the Manufacture De Bethune. This precision is reinforced by the self-regulating twin barrel and the presence within the regulating organ of the new silicon/platinum balance wheel with a flat terminal curve protected by the triple pare-chute shock-absorbing system.

Much like what can be observed from the sky, moon phases are read off by an exclusive display system by means of a platinum and blued steel sphere revolving on its axis and which is accurate to within one day every 122 years. In keeping with the Belle Epoque style, the solid back of the DB28 is inspired by the hunter-type shape of pocket-watches, and also incorporates a power-reserve indicator.

The principle of the flat end curve, placed on the same level as the balance-spring, compensates for off-centering and facilitates its fastening
Triple pare-chute shock-absorbing system reduces potential disturbances due to impacts to an absolute minimum and protects the balance-spring pivots.
