Good to know:
- Total revamp of the original Model No. 5
- Japanese made movement and parts with ball bearings from MinebeaMitsumi Inc. for the satellite hours display
- “Brand-new” condition with full set of accessories
Otsuka Lotec founder Jiro Katayama perhaps is one of the most celebrated contemporary Japanese independent watchmakers. Known for incorporating analogue apparatus into watchmaking, the design of his watches is unconventional and innovative.
Released at the beginning of 2025, the Model No. 5 Kai merges industrial instruments into Japanese watchmaking. It is a total revamp of the original Model No. 5, replacing the regulator-style mechanism with a satellite hour module with three rotating discs, being a new addition to Otsuka Lotec’s line up featuring exotic displays.
Otsuka Lotec’s watches are true representations of “Made in Japan” craftsmanship, fitting timepieces with Japanese made movements and components crafted in Katayama’s atelier. The present Model No. 5 Kai is fitted with a cal. 90S5 based movement manufactured by Miyota, in which it is renowned for outstanding reliability. For this particular model, ball bearings of MinebeaMitsumi Inc., a well-known Japanese manufacturer in mechanical parts, are used in the satellite hour module.
Freshly delivered in 2026, this timepiece is in “brand-new” condition and unworn, completed with its original accessories. For collectors that appreciate Japanese mechanics and craftsmanship, one should not miss this chance to acquire this desirable piece.
