NEW: De Bethune DB28GS ‘Yellow Submarine’

Think about the newly announced DB28GS Yellow Submarine as a combination of two watches – the DB28GS Diver, and the DB28 Yellow Tones.

Their first venture into yellow, created through thermal oxidation of grade 5 titanium, was used in ‘Yellow Tones’. The ‘Yellow Submarine’ has this same treated titanium used for the bezel, open case back, lug inserts, dial, hands and buckle. The middle of the 44mm sized case (thickness of 12.8mm) is black Zirconium.

The dial is satin-brushed yellow grade 5 titanium minutes with cut-out Arabic numerals. Functionally, along with the time is a power reserve indicator between 9 and 10 o’clock, a unidirectional rotating bezel, and the manual on-demand lighting for the dial. The hours and minutes hands are yellow titanium with lumed inserts and tips, the seconds hands is polished steel with a lumed tip.

Surrounding it is a rotating unidirectional sapphire crystal bezel with a metallised minutes ring. This is similar to the DB28GS Diver, which we have mentioned. Generally, all the numerals relating to the minutes counter are indicated on the bezel. For the DB28GS ‘Yellow Submarine’, as it was for the Grand Bleu, these indications appear on the sapphire crystal driven by the bezel.

The other (key) part that is also retained is the on-demand mechanically-driven blue light that illuminates the dial for a few seconds when activated.

This is achieved through a dynamo-driven lighting system. In broad terms, a dynamo is an electrical generator that creates direct current using a switch, but in this instance there are no electronics, no battery, just a mechanical watch movement. A pusher at 6 o’clock activates a small gear train which releases the energy stored in a second barrel. So gear train, by means of a miniature dynamo, provides the energy for the light.

The Calibre DB2080 movement is manually-wound with a five day power reserve, a titanium/ white gold balance wheel, beats at 28,800VPH, and includes their patented Triple Pare-chute shock absorption system. It has a mirror-polished yellow Grade 5 titanium motion-work bridge, the plate and barrel bridge are covered in the same yellow titanium and have the De Bethune ‘Microlight’ engraving, barrels are hand-snailed, and there is the usual high quality hand polished and chamfered finishing.

Water-resistant to 100m, the new DB28GS ‘Yellow Submarine’ is a limited edition of 25 pieces and comes with two straps. A canvas one with a pin buckle in yellow brushed grade 5 titanium, and a natural rubber strap with a yellow grade 5 titanium folding clasp.
