About the Grand Seiko Heritage
The Heritage Collection is described by Grand Seiko as the very heart of the brand. It brings back the designs and styles of the earliest Grand Seiko watches, including the 44GS and 62GS from 1967, reinterpreted with the latest movements, manufacturing techniques and craftsmanship. The aim, in the brand's words, is well balanced design that expresses the simple, pure essentials of watchmaking. The collection on the brand's site is organised into 44GS, 62GS, Spring Drive and Refined Essentials series, and it embodies what Grand Seiko calls a uniquely Japanese aesthetic.
