Grand Seiko will release a limited edition "45GS" reissue design. The lineup includes the stainless steel model shown in the photo and the 18K yellow gold model.
The 45GS, born in 1968, chose the Caliber 4520 as the heart of the watch, which has achieved stable accuracy against attitude differences and external disturbances. It was the brand's first hand-wound high-beat movement with 10 vibrations.
The design philosophy was based on that of the 44GS, which had been created the previous year and was considered the origin of the "Grand Seiko" style.
The flat windshield with a series of mirror-like surfaces without distortion, the edged sides of the case, and the numerous printings on the dial--"SEIKO" at 12 o'clock, "GS" at 6 o'clock, "HI-BEAT," "36000," the Daini-Seikosha logo mark, etc. --These are just like the "45GS" of the past.
The only difference is the see-through back and the movement that can be seen through it. The movement is the 10-oscillation hand-wound mechanical "Caliber 9SA4," which was completed just this year. The dual impulse escapement and twin barrels provide a power reserve of up to 80 hours.
The kohaze, which prevents the mainspring from rotating backwards, was designed in the image of the wagtails that visit the Grand Seiko Studio Shizukuishi. The way the balance wheel is pushed into the teeth of the square hole wheel looks as if a wagtail is pecking at it.
