About this reference

In 1968, Grand Seiko introduced the 45GS. This watch came just one year after the 44GS, the legendary creation that established the brand’s design code, the Grand Seiko Style. Although the two watches were nearly identical in styling, the 45GS featured a dramatic upgrade in terms of stability and performance with the brand’s first manual-winding high-beat movement, the Caliber 4520. Today, re-creation of this milestone is born. The original's angular case, which featured flat, mirror-polished surfaces and curved case sides, has been re-created using Grand Seiko's latest watchmaking technology. The dial colors and lettering are virtually identical to the originals. At the 12 o'clock position appear the Seiko letters, which have been made to reimagine the vintage character of the original. At the six o'clock position, one will notice the GS and Hi-Beat letters; the number 36000, which signifies the high frequency of the movement; and even the Daini Seikosha factory logo, indicating the birthplace of the original 45GS.
