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.
