DB28GS JPS Black and Gold

Exactly ten years ago, De Bethune started developing timepieces imbued with a more contemporary spirit, as embodied in the first DB28. Already at the time, Denis Flageollet –founder and Master Watchmaker of De Bethune as well as a keen outdoor sports enthusiast –felt the need to create watches suited to an active lifestyle.
Based on the observation that a sports watch must offer perfect legibility in all kinds of weather and every possible situation, the movement was developed from the outset in such a way as to light up the dial and movement from the inside. A white light source is thus produced by an entirely mechanical means that works on a dynamo-inspired principle. No electronics, no battery, entirely mechanical… A pusher at 6 o’clock serves to provide light on demand thanks to a gear train driven by the double barrel. By means of an original miniature dynamo, this gear train supplies the energy necessary to light up the face of the watch without affecting its operation and the energy necessary for the smooth running of its movement. This is a real challenge that is truly comparable to the highly technical operation of a minute repeater movement, in which the overall energy efficiency must be maximal and perfectly controlled. A few seconds of light are more than enough to read the time, even at night. The DB28 GS ‘JPS’ is black and gold, even in the dark.
