Full-Cataloguing
Good to know:
- Latest release by Otsuka Lotec in March 2026
- Inspired by mixing console nobs and sliders
- Jumping hours, retrograde minutes, running seconds disc
- “Like-new”, unworn condition with full accessories
Freshly introduced in March 2026, the Otsuka Lotec Model No. 8 is the latest release of the brand. Yet another rectangular-shaped wristwatch following Model No. 9 from last year, the present model can be seen as a watch of combined features of previous models, like jumping hours from No. 7.5, running seconds from No. 6 and complex aesthetics and exposed parts from No. 5 Kai.
Like all Otsuka Lotec watches, taking inspirations from analogue apparatus and instruments, the current model makes no exception. This time, Katayama implements the jumping hour display once again, referring to as the “hour channel”, featuring a nob-like pointer indicating the time; on the other hand, the minutes display takes form of a retrograde with red highlighted pointer. The hours and minutes displays are inspired by the REDD.37 tube mixing console from Abbey Road Studios, with the hour channel resembling the adjustment nobs, retrograde minutes sharing the looks of slider faders, and the mechanic disc of the retrograde taking the form of a tape recorder inner platter.
Fitted with a modified self-winding Miyota cal. 90S5, it is attached with an in-house movement on top. The ball bearings used in the module are made by MinebeaMitsumi, another Japanese manufacturer that has collaborated with Otsuka Lotec previously. The ball bearing, measured at 1.5mm, is currently the smallest in the world.
Offered in “like-new” and unworn condition, this is an opportunity to acquire the latest model by the Japanese independent watchmaker without long wait through the raffles system.
