Description
Produced in very small numbers, the Otsuka Lotec No.7.5 departs from mainstream horology. It replaces the traditional dial with a display built from rotating discs and precision-cut apertures. This layout resembles a laboratory instrument, emphasizing kinetic motion as the hours and minutes advance. The 40mm stainless steel case houses the automatic Miyota Calibre 82S5, chosen as a reliable foundation for the concept and aligned with the experimental vision of its creator, Jiro Katayama.
The No. 7.5 is available exclusively for Japanese residents, giving the watch a distinct JDM character. This geographic exclusivity increases its rarity for international collectors, further distinguishing this independent reference.
This pre-owned Otsuka Lotec No.7.5 Steel Watch comes with papers and box.
