- Jiro Katayama, the founder of the brand Otsuka Lotec, has gained a considerable following among discerning collectors. In 2024, the brand brought home the Challenge category at the Grand Prix d'Horlogerie de Genève (GPHG) garnering more attention for the Japanese brand.

- Despite its distribution being limited exclusively to Japan, Otsuka Lotec has garnered recognition globally for its steampunk-inspired and intriguing watch designs.

- The Otsuka Lotec Model No. 6 exudes a distinct steampunk vibe, with its case featuring a straight-grained finish and a bezel secured with eight screws, reminiscent of an analog metering device akin to an air pressure gauge. The monochromatic dial housing the retrograde hands has a raw, industrial design, with exposed screws and deliberate text elements that add to the overall steampunk aesthetic.

- Presented in “like-new” unworn condition, collectors can skip the wait and enjoy Katayama’s creation right away.
