Grand Seiko SBGA507 Heritage 44GS Kirazuri SS Blue Dial LIMITED

The Grand Seiko SBGA507 is a distinguished Heritage Collection release from 2024, a U.S.-exclusive limited edition of just 300 pieces. Its design pays homage to the iconic 44GS case first introduced in 1967, the very model that established the Grand Seiko Style with its Zaratsu-polished surfaces and striking light-shadow interplay. The cool blue “kirazuri” dial, inspired by the early evening sky over Lake Suwa and rendered using traditional mica powder techniques, delivers a subtle, sparkling texture that transforms under changing light. At its heart beats the celebrated Caliber 9R65 Spring Drive movement—Grand Seiko’s hybrid marvel—offering an impressive 72-hour power reserve and remarkable accuracy of ±1 second per day (±15 seconds per month). The watch features a screw-down crown, exhibition caseback, and a stainless steel bracelet with a three-fold push-button clasp, reinforcing both its technical prowess and everyday versatility. With 100 meters of water resistance and magnetic resistance of 4,800 A/m, this piece balances practical robustness with refined finishing. As a limited edition commemorating Grand Seiko Corporation of America, the SBGA507 holds a special place for collectors seeking both aesthetic beauty and horological significance. Excellent Condition with Grand Seiko box and papers dated 2024.
