Seiko Brightz SAGZ081 (Titanium)

The Brightz was Seiko's Japan-market line of titanium business watches, and the SAGZ081 is the blue sunray version: a 39 mm titanium case and bracelet under Seiko's hard coating, only 9 mm thick, with a sapphire crystal given a super-clear coating. The 7B24 movement is solar and radio-controlled, so it runs on light, sets itself from the time signal and keeps a perpetual calendar good until 2100, and it is rated to 100 m. The whole watch weighs 77 g. Seiko has discontinued it, and Japanese retailers such as Sakura Watches, which listed it at $376, now show it out of stock, so it is a watch to find used.
