Reasons to Bid

The De Bethune DB25L Spherical Moonphase Ref. DB25LRS1V1 is a striking marriage of technical mastery and poetic aesthetics. Encased in polished 18k rose gold, its 44 mm body feels both modern and traditional, offering a strong wrist presence without sacrificing refinement. At the heart of this watch is the patented spherical moonphase: a three-dimensional moon crafted from palladium and flame-blued steel, which rotates within a star-studded sky composed of finely polished steel and inlaid rose-gold stars. Powering the watch is the hand-wound Caliber DB2105V1, composed of 305 components, including a titanium-platinum balance wheel, and a self-regulating twin barrel that delivers a remarkable 6-day power reserve. This DB25 represents De Bethune’s mechanical engineering at its finest
