Designer
In-house design studio
The reference was drawn by the manufacture's internal design office, where case, dial and movement architects work alongside the watchmakers rather than as an outside commission.
Historical significance
Minase Five Windows 41 mm Silvered Platinum sits within Minase's Five Windows line, introduced in 2005. It carries the house codes established since 2005 — platinum 950 case, silvered opaline dial and eco-drive solar quartz — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- Early production dials show a slightly different minute track, and collectors pay a premium for them.
- The case is finished by hand, alternating polished and satin-brushed surfaces in a single pass so the edges stay razor sharp.

Brand history
Minase has spent more than 21 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Divido, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Kyowa Co. / Susumu Kitamura established Minase in 2005, working from Japan at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Minase calibre produced today.
