Arnold & Son Time Pyramid 18K Rose Gold Skeleton Dial

The Arnold and Son Time Pyramid reference 1TPAR.S01A.C124A is a striking example of contemporary haute horlogerie with its skeletal pyramid-shaped A&S1615 caliber that appears suspended between sapphire crystals. Housed in a 44.6 mm 18‑carat rose gold case, this manually wound masterpiece features a double-barrel system delivering a formidable 90‑hour power reserve. Central to its visual drama is the vertical linear gear train that runs from the double barrels at six o’clock to the balance at 12 o’clock, complemented by dual power‑reserve indicators elegantly framing the structure — a bold nod to regulator-style architecture inspired by John Arnold’s historical skeleton clocks. The see‑through dial arrangement layers subsidiary seconds, hour disc, and minute ring across three levels, yielding an immersive depth and spatial dynamic prized by collectors. Hand‑finished touches including hand‑chamfered bridges, Côtes de Genève, satin-finished wheels, and blued screws underscore its pedigree as an artisanal skeleton caliber. Though not a limited edition per se, the combination of its refined aesthetics, technical innovation, and in‑house movement make it a rare and desirable modern classic within the Arnold and Son oeuvre.
