Minase was founded in 2005 as a subsidiary of Sasaki & Co., a long-established Japanese tooling and precision-machining company based in Akita in northern Japan. Sasaki had been a supplier of precision tooling components to the broader Japanese watchmaking industry for decades; the Minase brand was launched as the company's own consumer watch programme, applying the tooling expertise to the production of distinctive dress watches in small batches. The Akita location gives the brand an unusual provenance - Akita is far from the Tokyo / Saitama centres of Japanese consumer-electronics watchmaking and is more associated with traditional Japanese craft industries.
Minase's signature is the multi-part case construction: cases composed of multiple polished components fitted together with extreme precision rather than single-piece machined cases. This construction approach allows complex case profiles with refined Zaratsu (distortion-free) polishing applied to each component face, and the visible joining lines become part of the design vocabulary rather than something to hide. The first major commercial reference, the Divido, established this construction approach: a 38mm steel case with multi-part polished/brushed surfaces and a refined dial layout.
Today Minase produces several hundred watches per year across the Divido, Horizon, 5 Windows (with five small windows on the dial showing different time and date elements), and various limited references. Movements are largely Miyota 9015 / Sellita SW200 automatic with Minase modifications and finishing. Pricing spans USD 4,500-12,000+ across the catalogue. The brand has built a small but devoted following among collectors of refined Japanese dress watchmaking outside the Grand Seiko ecosystem, and the Akita-based production model gives the brand an unusual identity in the broader Japanese watch landscape.
