The Grand Seiko SBGP009 (ref. sbgp009g) is a quartz dress watch, with a 40mm stainless steel case, 10.6mm thick, powered by the 9F85 movement. Water resistance is rated to 100m, under a sapphire crystal. Manufacturer MSRP is $3,100.
Grand Seiko SBGP009 owners note its "normal quartz" movement, and one owner criticizes the bracelet for lacking a taper. One owner cites a 40-year-old Seiko quartz watch that has only required battery changes as evidence of the reliability of Grand Seiko's quartz movements. On balance, owners value the Grand Seiko SBGP009 for its perceived long-term reliability.
