No. 7.5, A 40mm unworn stainless steel jumping hour automatic wristwatch, Circa 2026

The No. 7.5 continues Ōtsuka Lōtec’s exploration of instrument-inspired mechanical display systems, reducing the indication of time to three distinct apertures arranged across a stark monochromatic dial. Produced in limited quantities by Jiro Katayama, the model reflects the independent Japanese maker’s emphasis on engineered utility and unconventional mechanical presentation.
