Otsuka Lotec

Jiro Katayama of Otsuka Lotec continues to blur the line between horology and industrial art. His latest release, the No. 8, has just been introduced, drawing its aesthetic DNA straight from the golden age of analog studio gear. It is a masterclass in functional design, where the dial feels less like a watch and more like a high-precision audio interface.

Otsuka Lotec’s founder Jiro Katayama presents Nr. 5 Kai - The satellite hour watch that features rotating numeral disks that orbit like satellites, combined with fixed markers to indicate the time. To highlight the static satellite hour mechanism, careful design has been utilized to ensure the movement of the mechanics is clearly visible.
