The Grand Seiko SLGA015 (ref. slga015g) is a spring drive diver watch, with a 43.8mm titanium case, 13.8mm thick, powered by the 9RA5 movement and a 120-hour power reserve. Water resistance is rated to 200m, under a sapphire crystal. Manufacturer MSRP is $12,600.
The Grand Seiko SLGA015 is widely praised for its exceptional accuracy, with owners reporting performance far exceeding the stated 10 seconds per month. The Spring Drive movement's smooth sweep and 5-day power reserve are also noted strengths, as is the lighter titanium case construction. However, some owners find the bracelet extension non-intuitive, and one noted the clasp scratched easily. The watch features a nature-inspired, wave-like dial texture. Overall, owners rate the Grand Seiko SLGA015 highly for its impressive accuracy and quality construction.
