This interview delves into the origins and philosophy behind Otsuka Lotec, Japan's indie watch brand known for its steampunk-inspired, industrial designs. Founder Jiro Katayama, with a background in automotive and product design, discusses his journey into watchmaking, his self-taught methods, and the unique inspirations drawn from vintage instruments and machinery. The conversation highlights the brand's commitment to originality and craftsmanship, despite its JDM-only status and growing international recognition.
Jiro Katayama's interest in watchmaking began around 2008 with the impulse purchase of a small lathe, initially intended for practicing operations by making a watch case.
Katayama acquired most of his watchmaking knowledge through web searches, imitating disassembled movements and videos, and a process of trial and error.
The first piece Katayama made was a brass case, "No. 1," which taught him about material properties and design techniques like planning with assembly in mind.
Katayama's background in automotive and product design proved valuable for mastering proportional balance, layout, and surface composition in watch design.
Otsuka Lotec's designs are inspired by industrial products predating Katayama's era, such as vintage cameras, industrial gauges, and machinery, which he feels express creator individuality more strongly.
Katayama consciously moves away from traditional watch designs, favouring a raw, industrial aesthetic and a strong sense of three-dimensionality in his watches.
Initially, Katayama manufactured all components, including cases and lenses, at home using readily available materials and tools.
Collaboration with Hajime Asaoka and Precision Watch Tokyo has allowed Katayama to dedicate more time to the creative process, though his design and prototyping methods remain the same.
