Grand Seiko Watch Spring Drive. SBGA203G The classic Grand Seiko Spring Drive has remained one of the brand’s most legendary and collectible models combining the motive force of a mainspring found in mechanical watches with the high precision of a quartz watch. Its impeccable precision was years in the making, beginning in 1977 when a young Seiko engineer known as Yoshikazu Akahane had the dream to create a watch with a one-second-a-day accuracy. It took him 27 years and over 600 prototypes, but eventually the Grand Seiko Spring Drive watch collection was born, and its success was guaranteed. Boasting a perfect glide motion of the seconds hand, a 72 hour power reserve and a +/-1 second per day accuracy, this Grand Seiko Spring Drive watch is home to the 9R65 Spring Drive movement. Its flawless construction can be witnessed through the see-through case back and on the black coloured dial where multifaceted hands and markers deliver hours, minutes and seconds function, a date window at 3 o’clock and a power reserve indicator. The Grand Seiko Spring Drive watch continues to impress with a handsome stainless steel case measuring to 41mm in diameter and 12.5mm in thickness equipped with a 100 metre water resistant screw in crown, a stainless steel bracelet with three-fold clasp and push button release and dual curved sapphire crystal glass, a material famed for its scratch resistance and anti-reflective coating.
