In Tokyo, Japan, lies a hidden gem in the watchmaking industry, Ōtsuka Lotēc. Despite its low profile, even among Japan’s enthusiastic watch collectors, this independent brand holds a special place in the world of horology. Founded by Jiro Katayama in 2008, a former product designer who transitioned into a self-taught watchmaker, Ōtsuka Lotēc is renowned for its handcrafted timepieces. Each watch is meticulously assembled by Katayama himself in his modest Tokyo workshop. With a background in the automotive industry, his passion for cars is intricately woven into the design of his watches, creating a unique blend of mid-century engineering aesthetics and a hint of retro-futurism.
The No. 6 watch, part of a limited series including the No. 5, No. 7, and No. 7.5, is particularly noted for its analog meter, fan-shaped, retrograde display reminiscent of an air pressure gauge. The reissued model remains faithful to its original 40mm size but comes in a sleeker 11.8mm-thick case. Technical enhancements include an integration of the dial directly onto the MIYOTA 9015 automatic movement, ensuring a seamless fit with the bezel. The watch’s design elements are not just a nod to aesthetics but are also a testament to Katayama’s commitment to preserving the watch’s unique identity while enhancing its functionality and wearability.
The new No. 6 watch showcases a fan-shaped dial with hours and minutes displayed parallel to each other and sharing an axis at the 6 o’clock position. A central seconds disk and a date display to the right add to the watch’s functionality. The move from SUS303 to the more robust SUS316L for the case material, along with the upgrade from mineral to sapphire crystal glass, reflects the brand’s commitment to using high-quality, durable materials.
Despite the global appeal of Japanese watches, Ōtsuka Lotēc has retained a sense of exclusivity and mystery, largely due to its limited availability and reluctance to participate in interviews outside of Japan. Katayama’s transition from automotive to watch design showcases his multifaceted creativity and dedication to creating objects that reflect his unique worldview. His approach to design emphasizes the need for newness and innovation, a philosophy that’s vividly expressed in the No. 6 watch’s design.
The brand’s name, Ōtsuka Lotēc, reflects Katayama’s affinity for low-tech, mechanical objects, a stark contrast to today’s high-tech world. The No. 6, with its VU meter reminiscent dial and industrial vibe, is a clear expression of this philosophy. Technical challenges in creating such a piece were met with precision and innovation, particularly in the retrograde hours and minutes complication, a feature powered by the reliable Miyota movement.
While Ōtsuka Lotēc’s watches are currently exclusive to Japan, the brand’s methodical approach to production and expansion hints at a possible future where these unique timepieces might be available to a global audience. For now, the brand remains a hidden gem within Tokyo, representing the pinnacle of Japanese craftsmanship and design innovation. As watch enthusiasts and collectors worldwide continue to seek unique, high-quality timepieces, the allure of Ōtsuka Lotēc and its No. 6 watch will undoubtedly grow, marking the brand as one to watch in the coming years.
