The SEIKO "5 Actus" was produced in the late 1960s and was a very popular model among young people at the time due to its sporty design. Even today, its sophisticated design is highly regarded. The dial is a rare dark gray dial with a glossy finish that is close to black. It is an attractive dial that changes its appearance depending on the viewing angle and the angle of light. The "SEIKO" logo and "5 ACTUS" are applied at the 12 o'clock position, and "21 JEWELS" and the logo mark indicating "Kameido Seikosha (SEIKO) made" are applied at the 6 o'clock position.
