De Bethune debuts a diver’s watch in colours of fire

The DB28GS “Yellow Submarine”, a limited edition of 25, seems an impossible combination of water and fire. The DB28GS was designed and developed to be a resolutely sporty watch. Therefore, to illuminate the watch and the movement from the inside, a light source is produced by a fully mechanical means that works on the dynamo principle. A pusher located at 6 o’clock activates a small gear train driven by the twin barrel. This gear train, through a miniature dynamo, provides the energy to light the watch. The minutes counter indications appear on the sapphire crystal driven by the bezel. Hand-wound, with central seconds and a five-day power reserve indicated on the dial, the movement is equipped with a state-of-the-art in-house-made balance wheel. The calibre is also equipped with the triple pare-chute system. Water-resistant to 105 m, the model is delivered with two straps: a canvas version and a striated natural rubber iteration with titanium folding clasp.
