Description

The DB28 GS Grand Bleu is the first 100% sport watch created by De Bethune: a diver's watch featuring a unidirectional rotating bezel and offering water resistance to 10 bar (100 metres / 330 feet) and readability even in poor light conditions.

The 44 mm case offers great comfort thanks to the lightness of titanium, the 12 o’clock crown position and, above all, the presence of the patented system of floating lugs that adapt to wrist size and movements.

A special lighting system illuminates the watch and the movement from the inside. The slightly bluish white light source is produced by a fully mechanical means that works on the dynamo principle.

A pusher at 6 o'clock activates a small gear train driven by the twin barrel. This gear train, by means of a miniature dynamo, provides the necessary energy for lighting the watch. A few seconds of light is more than enough to read the time, even in the middle of the night.

The case is enhanced by a rotating bezel enabling the wearer to calculate immersion time. But, in this case, the indications are not on the bezel itself but on the sapphire crystal driven by the bezel.

A new calibre; water resistance to more than 100 metres; excellent readability including in the darkest depths thanks to ingenious lighting inside the movement and a new photoluminescent blue, a different bezel that rotates this time with the crystal to indicate dive times; a titanium case for a light feel and a rubber strap for convenience; along with a five-day power reserve.
