Inspired by the Seiko archives, this timepiece features elements from the popular ‘Time Sonar’ watch, in an SKX shape.
The eye catching original 1970s design was famous for its unique translucent dial showing the day/date disc rotation and its highlight red-orange colour Second hand which are echoed in this modern redux.
The watch shape echoes the SKX series of Seiko 5 Sports watches – 1990s versions which updated the 1960s originals.
