Grand Seiko Heritage 45GS Limited SLGW005
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.

About Grand Seiko
Grand Seiko emerged in 1960 as a high-end watch line from Seiko, aiming to challenge Swiss dominance in luxury watchmaking. The brand quickly established itself with Japan's first chronometer-grade watch and later gained renown for its innovative Spring Drive technology, which combines the best of automatic and quartz movements. In 2017, Grand Seiko became an independent entity, solidifying its position in the luxury watch market.
The brand's design philosophy, known as the "Grammar of Design," was established in 1967 with the Grand Seiko 44GS. This aesthetic approach emphasizes legibility, refined appearances, and distinctive features like multi-faceted markers and hands, a half-recessed crown, and the meticulous Zaratsu polishing technique. Grand Seiko continues to push boundaries in watchmaking, as evidenced by recent innovations like the "Kodo Constant-Force Tourbillon," while maintaining its commitment to precision engineering and unique design language.
