Seiko 5 Sports SKX Sea Green Skeleton Style SRPJ45K1 Inspired by the Seiko archives, this timepiece features elements from the popular Seiko Time Sonar watch, now presented in an SKX shaped Seiko 5 Sports case design. The eye catching original 1970s 'Time Sonar' watch was famous for its unique design features, which are incorporated in this modernised version. The signature translucent dial showcases the day/date disc rotation and its Sea green dial with highlight red-orange Second hand add to the retro effect. Powered by the Seiko in-house 4R movement, the watch shape echoes the SKX series of Seiko 5 Sports watches - 1990s versions which updated the 1960s originals. Seiko 5 Sports is known for over fifty years of reliability, durability, performance and value. 5 represents the original five key features of every Seiko 5 still present today: Automatic movement, Day-date display, Water Resistance, Recessed crown and Durable case and bracelet. Date is either English or French.
