Crafted by self-taught Japanese watchmaker Jiro Katayama in his Toshima, Tokyo workshop, this 42.6mm stainless steel timepiece reimagines the humble analog meter-think vintage gauges or steampunk instrumentation-with a distinctive fan-shaped (Japanese sensu-inspired) retrograde display. Its coaxial retrograde hour and minute hands sweep across the lower dial before snapping back instantly, paired with a central running seconds disc and a practical date window. Powered by a modified Miyota 9015 automatic movement enhanced with Katayama's in-house retrograde module, it delivers refined finishing, a slim 11.8mm profile, and sapphire crystal protection in its updated form. What truly sets the No.6 apart is its extreme rarity. Production remains tightly controlled, historically limited to just a few dozen pieces annually even after scaling up with borrowed help from peers like Hajime Asaoka. Acquisition is restricted to periodic lottery systems open only to buyers with Japanese credit cards and addresses, turning ownership into a coveted privilege rather than a simple purchase. Recognized with the GPHG Challenge Prize in 2024 for watches under CHF 3,000, the No.6 blends inventive 'low-tech' ingenuity, mechanical charm, and near-mythical unobtainability-making it a true collector's grail for those who prize originality over accessibility.
