FEATURES
Seiko 140th Anniversary Limited Edition
The release in January 2021 of a new re-creation of the first Grand Seiko from 1960 opens a year of celebration of the 140th anniversary of the company's foundation.
This commemorative timepiece offers a remarkable blend of slimness, efficiency and precision. The case is just 10.9mm in depth, the power reserve is 72 hours and the accuracy rate is +5 to -3 seconds per day, all made possible by the hand-winding Caliber 9S64 which powers the watch.
The case and indexes are in 18k gold and the anniversary is marked by the trademark "S" engraved on a gold plate set into the movement's bridge. Kintaro Hattori registered this mark in 1900 as the symbol of the Seikosha factory.
