Designer

Jörg Hysek

Jörg Hysek left Rolex and Seiko's European studios to build a design practice in Geneva, giving houses such as Vacheron Constantin, Breguet, Seiko and TAG Heuer their sculptural, architecture-led cases before founding his own brand, HD3.

Historical significance

Grand Seiko Elegance 39 mm Slate Sapphire sits within Grand Seiko's Elegance line, introduced in 1963. It carries the house codes established since 1960 — sapphire crystal case case, slate grey dial and spring drive — and is one of the references collectors use to date the evolution of the collection.

Interesting facts

  • The movement's bridges are decorated even where they will never be seen once the watch is cased.
  • 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.
