Inspired by the golden era of avant-garde watchmaking and the philosophy of the great independent makers, the ARYON NATURE places a genuine natural stone dial at the very heart of its design — where every single piece is, by definition, one of a kind. Key Highlights: One-of-a-Kind Natural Stone Dial: Each dial is hand-cut from a solid slice of natural stone, so that its veining, inclusions and depth of colour are completely unique. No two watches are alike — because no two stones are alike. This is the trait collectors prize most in fine watchmaking: a dial that simply cannot be reproduced. Available in two editions: Lapis Lazuli (deep ultramarine with golden pyrite flecks) and Black Obsidian (dense volcanic glass). Timeless Minimalist Design: 40mm 316L stainless steel case with a clean, refined architecture and an integrated solid steel bracelet. The dial is presented free of numerals or superfluous text — pure minimalism that lets the stone speak. Reliable Mechanical Heart: Powered by the robust Japanese Miyota 8315 automatic movement — the longest-running mechanical caliber Miyota ever produced, offering up to 60 hours of power reserve, and now discontinued. Visible through the exhibition caseback, with an individual serial number engraved on the back of each piece. Premium Materials: Ultra-scratch-resistant sapphire crystal on the front, and 50 meters (5 ATM) water resistance ensuring true everyday versatility.
