Re-creation of the 45GS captures the heritage and evolution of Grand Seiko’s high-precision watchmaking.
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.
Caliber 9SA4 was created to provide the ultimate hand-winding experience, with a winding sound and feel demonstrating its craftsmanship and quality.
It has a high frequency of 10 vibrations per second, which leads to stable precision, and a long power reserve of up to 80 hours.
