Immerse Yourself in the Mechanical Universe of Jiro Katayama's New Otsuka Lotec No. 9
Stepping into the limelight with a unique take on horology is designer Jiro Katayama with the Otsuka Lotec No. 9, a timepiece reminiscent of vintage Japanese electric meters. In a departure from the ornate finishes typical of haute horology, this instrument embraces an unapologetically industrial aesthetic while cramming in several complicated features that positively speak of luxury watchmaking.
With its 30mm x 13mm rectangular case and a 44mm lug-to-lug measurement, the Otsuka Lotec No. 9 bears resemblance to classic styles like the Reverso or Tank. Technically, it is far from the ordinary, boasting of a slew of intricacies such as jumping hours, rewinding minutes, a tourbillon, hour-striking feature, and a power reserve indicator. The hours and minute markings are cleverly illuminated from below, aiding in low-light legibility. Another compelling feature is the uniquely designed hour-striking function that brings forth an industrial chime, enhancing the timepiece’s brilliant concept.
The watch case, accentuated by double circular slotted screws, exposes the mechanical components and power reserve indicator from the side, allowing the wearer to appreciate the enigmatic dance of the internal gears. Completing the whole ensemble is a calf leather strap tapering toward the buckle for an ideal balance between style and comfort.
True to his innovative spirit, Katayama intends for the Otsuka Lotec No. 9 to bring to the wrist the texture, vibrations, and sounds of an intricate piece of remarkable industrial machinery. With a price tag of around $108,000, this timepiece is certainly an aspirational testament to the audacious novelty of watchmaking.
