Distinguished by its unconventional double-retrograde display, the No.6 presents hours and minutes on opposing arched scales, evoking the gauges and instrumentation of vintage machinery—a recurring theme in Katayama’s industrial design language. Powered by a Miyota automatic movement fitted with Katayama’s proprietary retrograde module, the watch combines mechanical ingenuity with striking visual originality. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eIts appeal was formally recognized when the No.6 won the prestigious Challenge Watch Prize at the 2024 Grand Prix d’Horlogerie de Genève (GPHG), awarded to the best watch under CHF 3,000. Produced in extremely limited quantities and available primarily through a Japan-only lottery system, the No.6 has become one of the most sought-after independent watches of recent years, celebrated for bringing avant-garde design, authentic craftsmanship, and accessible pricing into a single award-winning creation.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eAll our watches are thoroughly inspected by our expert watchmaker and come with a 3 months guarantee.
