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 Horizon 37 mm Meteorite Sapphire sits within Minase's Horizon line, introduced in 2005. It carries the house codes established since 2005 — sapphire crystal case case, meteorite dial and spring drive — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- The reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.
- The bracelet tapers across its length, which is why the profile looks thinner on the wrist than the specification suggests.

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.
