De Bethune – DB28GS Grand Bleu

2nd September 2019 // By Roberta Naas

This watch from independent brand De Bethune represents a host of firsts. It houses an all-new caliber, is the brand’s first dive/water watch, is equipped with exclusively developed lighting and features a bezel that rotates the crystal to indicate dive time. De Bethune worked in tandem with James Thompson of Black Badger Advanced Composites and with Super- LumiNova to create both the lighting and unique shade of blue that is now proprietary to De Bethune.

The photoluminescent blue light source, named Blue Moon, illuminates the watch and movement from the inside to improve readability of the hands, indices and timer.

It is created by a mechanical system that works on a dynamo principle, so when the pusher is activated, the necessary energy is provided to light the watch via a gear train. The 400-part DB2080 hand-wound movement powers the 44mm watch, which is water resistant to 100 meters.

Price: $93,500 in titanium with black zirconium
