Seiko’s barrier-free watches.
Their history began before World War II.Tactile watch
In 1939, a barrier-free pocket watch was developed for the visually impaired, which allowed them to open the front cover and read the time by touching the hands and the protrusions on the dial with their fingers. The movement is a type 19, 7-jewel movement that was also used in railroad watches. In 1966, the company developed a tactile wristwatch. The hand-wound mechanical movement, Caliber 6618, has a special structure that meets the requirements for dust, corrosion, and moisture resistance, and the hands are made of sweat-resistant stainless steel. In 1979, Seiko also developed the world's first quartz tactile wristwatch. It received the Good Design Long Life Design Award from the Japan Institute of Design Promotion in 1980. The evolution of tactile watches has continued uninterrupted since then.
