New 72-hour power reserve to make collection more accurate.
Seiko is launching a series of limited edition watches to celebrate the 50th anniversary of the Grand Seiko standard.
The 800-piece collection comprises six Spring Drive, quartz and mechanical watches. Each watch in the Grand Seiko Anniversary Collection has a new 72-hour power reserve movement that offers a higher level of accuracy of between -1 and +5 seconds per day.
Each watch shows the Grand Seiko lion emblem on the dial, or in the case of the Spring Drive and mechanical models on the oscillating weight, in 18 carat gold. All carry the inscription “50th Anniversary 1960-2010” as well as the individual serial number on the case back.
The Grand Seiko standard was developed in 1960 and since then every mechanical Grand Seiko watch ever built has exceeded the internationally accepted chronometer standard. “From the very first Grand Seiko watch in 1960 until the all-new 36,000 vph automatic caliber of today, every Grand Seiko watch has shared the functional beauty and design purity that are now its hallmark,” said Seiko.
