MINASE, Japanese watches that will be treasured for more than 100 years.
Craftsmanship
MINASE watches are made by true monozukuri, the Japanese art of craftsmanship.
At our atelier in Minase, Akita Prefecture, where even the landscape is similar to Joux Valley, the mecca of the Swiss watch industry, our craftsmen handcraft watches by themselves.
We take a look at the various skills used, the MORE structure, sallaz polishing, the case-in-case design, and more.

MORE Structure
To make watches that will be treasured for more than 100 years, MINASE developed a patented structure called “MORE (Minase Original Rebuilding Equation).” Inspired by traditional Japanese wooden puzzles, all the external parts, including the case and bracelet, can be assembled and disassembled repeatedly like a wooden puzzle.

SALLAZ Polishing
A polishing technique for preparing the substrate, which has almost been lost even in Switzerland. The work relies on skilled craftsmen’s sensitive fingertips to produce a distortion-free mirror surface. Various parts of MINASE watches, including the case, dials, and bracelet, feature sallaz polishing.

Case in Case
The case-in-case design is one of the key characteristics of the MINASE HiZ series.
The dial contained in the case acts as a second case to cover the movement, which is held by another index from the top. This original structure is unique to MINASE.
