Otsuka LotecNo. 5 Kai Steel Watch No 5 Kai

Description

The Otsuka Lotec No. 5 Kai is a 40.5mm stainless steel watch from the Tokyo independent brand Otsuka Lotec, known for unconventional mechanical displays. Instead of conventional hands, hours appear on a rotating numeral disk that jumps instantly at the roller near 8 o’clock, twice every hour, while the minutes are read on a fixed curved scale on the right side of the dial. A three-armed satellite structure sits at the center of the dial, with exposed gears, screws and gold-toned elements visible beneath a domed sapphire crystal with anti-reflective coating. Japanese characters for Lotec and Tokyo appear on the dial. The watch is powered by the self-winding Miyota 90S5 movement with an in-house satellite hour module, offering approximately 40 hours of power reserve. The solid steel caseback is engraved with the brand name and Tokyo, Japan. The case is only 7.6mm thick without the crystal and is fitted to a black calfskin strap in 22mm lug width. Otsuka Lotec builds small numbers of watches that treat the dial as a mechanical sculpture, which makes the No. 5 Kai an appealing piece for collectors of independent Japanese watchmaking.

This is a Pre-Owned Otsuka Lotec No. 5 Kai Skeleton Dial Steel Watch. It comes with the manufacturer’s box and papers.
