The Ōtsuka Lōtec No.9 integrates five complications into a square industrial case that redefines mechanical watchmaking. Its features include a jumping hour, retrograde minutes, a striking mechanism, a tourbillon, and a 40-hour power reserve indicator. The right half of the dial displays layered hour and minute discs illuminated by a luminous block, enhancing visibility in low light while underscoring the watch’s dramatic aesthetic.
Measuring 44 by 30 millimeters, the stainless steel case pairs with a curved solid back and a wide calfskin strap for balanced wearability. At its core is the in-house Cal. SSGT hand-wound movement with 278 components, including ruby bearings and miniature ball bearings that improve efficiency. With water resistance to 3 ATM and production limited by its complexity, the timepiece positions itself as both a technical showcase and a daring statement of contemporary horology.
