This 40mm 316L stainless steel timepiece channels the spirit of vintage 1930s turret-lens 8mm film cameras, featuring three prominent, lens-like apertures arranged in a distinctive asymmetrical layout on its upper case-evoking a steampunk-industrial futurism that's instantly recognizable and utterly unique. At its core lies a modified Miyota 82S5 automatic movement enhanced by Katayama's proprietary in-house jumping-hour module: the hour numeral snaps instantly into view through the top window, while separate rotating discs display minutes and running seconds below in their own fisheye-style ports. The updated version boasts dual sapphire crystals (front and display case back), refined straight-graining contrasted with sandblasted textures, a slim 11.2mm profile, 20mm wire lugs, and a knurled crown at 4 o'clock reminiscent of a watchmaker's screwdriver. Its true allure, however, lies in extreme rarity. Ōtsuka Lōtec caps total annual production at under 200 pieces across all models, with sales restricted exclusively to Japan through periodic lottery raffles requiring a Japanese billing address and domestic credit card. This JDM-only barrier, combined with high global demand from collectors chasing Katayama's inventive designs, transforms ownership into a rare privilege. Like its sibling the No.6 (a 2024 GPHG Challenge Prize winner), the No.7.5 embodies mechanical ingenuity, bold originality, and near-mythical scarcity-making it a must-have grail for those who value true indie exclusivity over mainstream accessibility.
