This time, Seiko presents the Prospex Speedtimer SFJ007 in 42mm with a hardened steel case and coating. Its bracelet, also made of steel and in black color, features a three-fold clasp with a push-button release. The dial incorporates yellow tones on the hands and a shiny black background reminiscent of the lunar surface, in addition to providing lumibrite to the hands and indices—a photoluminescent substance that absorbs natural light during the day to emit it gradually in the dark. Thanks to solar movement, when fully charged, the piece can last up to six months. The watch is designed to meet the needs of diving enthusiasts, hikers, or extreme sports lovers.
