Swiss luxury watch manufacture De Bethune celebrates ten years of commitment to the Monaco Association against Muscular Dystrophy and revisits on this occasion the model designed for the first edition of Only Watch in September 2005.
Ten years ago, David Zanetta and Denis Flageollet, founders of De Bethune, decided to support the Only Watch project – an auction placed under the patronage of Prince Albert II of Monaco on behalf of research into Duchenne Muscular dystrophy – by creating the first DBS, an incredibly high-tech model with an innovative design.
In 2005, the DBS laid the first foundations of what has now become one of the watch industry’s most innovative and creative R&D labs. Youthful engineers under the guidance of Denis Flageollet have given rise to several unprecedented developments, world firsts and the ten patents filed by the Manufacture since its creation in 2002.
The cone-shaped lower lugs, along with the 12 o’clock crown, were subtle details that counter-balance the almost imposing size of the model measuring 45 mm across at its widest point. Continuing this approach, a pivoting gold plate connects the upper section of the strap and the case middle: this was in fact the forerunner of what would later be known as floating lugs – a patented system featuring a spring-type effect that helps adjust to the size of the wrist and its movements.
Calibre DB2115 powering this one-of-a-kind model illustrates the expertise and ingenuity of this “grand” little independent firm through fine innovations such as the self-regulating twin barrel ensuring a six-day power reserve, along with the pairing of the silicon/white gold balance and its balance-spring with flat terminal curve that ensures an ideal mass/inertia ratio and delivers an optimal frequency of 28,800 vibrations per hour suited to wristwatches.
