Historical significance
Grand Seiko Sport 41 mm Meteorite Quartz sits within Grand Seiko's Sport line, introduced in 1981. It carries the house codes established since 1960 — quartz tpt case, meteorite dial and automatic, swiss lever escapement — 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 bracelet tapers across its length, which is why the profile looks thinner on the wrist than the specification suggests.

Brand history
Grand Seiko has spent more than 66 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Heritage, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Seiko / Daini & Suwa Seikosha established Grand Seiko in 1960, working from Japan at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Grand Seiko calibre produced today.
