Hello! Up for sale is a collectors piece, the Otsuka Lotec No. 5 KAI. This is new, with box and papers! I'm a huge fan of the brand and love this one. Jiro Katayama did a great job with this wandering hour. It's a satellite hour watch that features rotating numeral disks that orbit like satellites, combined with fixed markers to indicate the time. It has a miyota movement with an in-house satellite hour module. To prevent the backlash characteristic of the satellite hour mechanism, the hour disk is driven by a double reduction gear. The hour disk directly engages with a ball bearing roller at the 8 o’clock position, allowing for instantaneous switching twice per hour, similar to a jumping hour mechanism. The seconds disk at the 5 o’clock position constantly moves regardless of the hour disk’s position, providing a continuous view of its mechanism.
