The dial reads like a nocturnal scene: a jumping hour in an aperture, minutes on a rotating disc, and a central spherical moon phase inclined at 60 degrees. Its pair of polished hemispheres in palladium and flame-blued steel are accurate to within one lunar day every 1,112 years. Building the dial are 82 elements including blued titanium worked with a random guilloché alongside a hand-guilloché barleycorn motif, pairing classical watchmaking with a contemporary finish. Beneath, a micro ball-bearing system drives the jumping-hour display and rotating minute disc, visible through a sapphire caseback and featuring a self-regulating twin barrel and titanium-and-grey-gold balance wheel. Slender, openworked lugs with the brand’s signature bullet shape hug the wrist, while an extra-supple alligator strap and matching titanium buckle complete a piece that joins the iconic collection perfectly; DeBethune.ch.
