De Bethune celebrates its 10’th anniversary this year. On this Occasion, the independent Swiss watch manufacture presents a new collection DB27 and unveiling its first model DB27 Titan Hawk.
In the village of L’Auberson, expert hands meticulously craft the grade 5 titanium, displaying perfect mastery of the delicate mirror-polishing technique gracing the case, the floating lugs and the domed back of the Titan Hawk. The floating lugs are fitted with a patented system of springs that enables the watch to adjust to the wrist and to its wearer’s movements, in harmony with De Bethune’s consistent concern for comfort and for cutting-edge aesthetic appeal.
The silver-toned colour of the grained dial sparkles in the centre thanks to the microlight accompanying the central calendar read-off, surrounded by a chapter ring and minute circle featuring a rounded shape and raised numerals. The cut-out hands including the atypically shape date pointer are in steel, hand-polished and flame-blued in the De Bethune workshops, where time-honoured know-how is combined with technical mastery and artistic genius.
The DB27 Titan Hawk is equipped with a mechanism boasting the kind of proven technical features dear to Denis Flageollet, who continues to broaden and perfect the technical knowledge of the Manufacture. The silicon and white gold annular balance wheel revealed through the case-back powers the latest self-winding in-house calibre – driving the central hour, minute and date functions – named S233 after the specific gravity of silicon.
Model: DB 27 Titan Hawk
Functions: hours – minutes – date
Calibre S233 – mechanical self-winding
Mainplate hand-decorated and snailed, hand-chamfered and polished steel parts
The S233 movement incorporates the major De Bethune technological breakthroughs:
– Self-regulating twin barrel: The barrels are specifically designed to eliminate friction and efficiently transmit a maximum of energy.
– Silicon/white gold balance wheel with flat terminal curve: Its exceptional lightness enables this balance wheel to reduce mechanical friction and deliver an ideal inertia/mass ratio. The principle of the flat end curve, placed on the same level as the balance-spring, compensates for off-centering and facilitates its fastening.
– Triple pare-chute shock-absorbing system: reduces potential disturbances due to impacts to an absolute minimum and protects the balance-spring pivots.
