A landmark of modern watchmaking, this unique De Bethune Dream Watch 1, Ref. CS152, makes its auction debut. Cased in the brand’s signature blued titanium, it represents the perfect convergence of avant-garde design and technical mastery. From the moment it graces the wrist, the Dream Watch 1 defies convention. Its case is an architectural marvel, celebrated as the first in watchmaking to feature floating lugs beneath while remaining absent from the top. This revolutionary design, complemented by the crown placed boldly at 12 o’clock, establishes a new paradigm for comfort and aesthetic daring. The entire case and dial are crafted from blued Grade 5 titanium, showcasing De Bethune’s most poetic innovation. Through a proprietary thermal process, the titanium itself is transformed, revealing an astonishing, cosmic azure blue—a colour born of alchemy that captures the depth of a twilight sky and the vibrant signature of De Bethune’s spirit. The semi-openworked dial offers a captivating view into the heart of the watch. At its center, the highly advanced silicon balance wheel, encircled by a white gold ring, creates a unique mirror-like effect. Below, the three-dimensional spherical moon-phase at 6 o’clock is a masterpiece of precision and beauty, accurate to just one lunar day every 122 years. True to its innovative core, this Dream Watch 1 features the groundbreaking adjustable chronometrical regulator system. For the first time, the pinnacle of mechanical precision is placed directly in the owner’s hands. Via two pushers on the caseback, one can personally fine-tune the watch’s accuracy, adjusting its rate by approximately one second per day. The caseback also features a discreet power reserve indicator, completing the technical picture. More than a watch, this unique Dream Watch 1 is the crystallization of De Bethune’s philosophy—a landmark achievement and a rare opportunity to acquire a cornerstone of modern independent watchmaking.
