Brand Story
Jiro Katayama worked as a product designer for automobiles and household goods before dedicating himself to watchmaking. In 2011, he launched Otsuka Lottec as a one-man workshop. Working in small batches, his design-led retrograde and jump-hour watches quickly gained viral popularity online among collectors, making them extremely difficult to acquire.
Design Language
The brand’s design language is industrial and steampunk. The dials resemble mechanical pressure gauges or camera lenses, utilizing rotating discs, retrograde needles, and magnifying lenses over window displays.
Movements & Manufacturing
Otsuka Lottec watches utilize reliable Miyota automatic base movements, which Katayama fits with proprietary in-house retrograde and jumping hour complication modules designed and adjusted in his Tokyo studio.
Notable Models
No. 6 is a highlight of their production line.
Why Enthusiasts Care
Katayama’s creations are highly original, escaping standard Swiss styling. They represent a playful, mechanical-art interpretation of timekeeping, blending industrial design with indie Japanese watchmaking craft.
