De Bethune’s new diver, introduced late last year and affectionately called the Yellow Submarine, brings a whole new look to the dive genre. While the DB28GSVY embraces the warmer tones of gold, amber and orange, its case and components are not crafted in gold but are actually made from heat-treated titanium and steel.
Mounted on De Bethune’s articulated case/lug platform, the Yellow Submarine embodies the past and future of watchmaking in a single case. Space-age design and materials are married to traditional watchmaking solutions and then taken to the next level.
Powering the watch is the DeBethune manual-wind caliber DB2080, which is comprised of 400 individual components, including 51 jewels. Power reserve is stretched to five days thanks to a dual-barrel system as well as the fine-tuned escapement, with its titanium balance, white gold inserts and a profile designed to minimize fluid friction. The balance wheel cycles at 28,800 beats per hour.
Releasing power to the unique balance is an escape wheel crafted in silicon. The entire escapement assembly is protected by a triple Pare-Chute system developed in-house by De Bethune. Other unique aspects to this particular timepiece include that it eschews the normal practice of slathering luminous paint everywhere to read the time. Only the hands have slim strips of lume while an amazing electro-mechanical system creates light via a micro-dynamo and LED lighting system activated by the push of the actuator at 6 o’clock.
Push the button and watch the repeater-like regulator spin while four LED sources cast light across the dial. Since this is technically a dive watch it also incorporates a rotating bezel, but in this case the outer coin-edge grip actually rotates an inner rehaute with pierced cutouts showing beautiful blue numerals. The 44mm case mounts the crown at 12 o’clock. Each example of the twenty-five in this very limited edition is priced at $110,000.
