Seiko 5 Sports Black Grape GMT SKX Re-interpretation Mens Watch SSK001K1 First released in the 90s, the SKX Seiko 5 Sports watches were a modernised version of the classics - updating the reliability and durability of the 1960s originals. The 90s collection offered improved practicality - enhanced water resistance, strengthened crystals along with luminous hands and hour markers. These wearable, loveable values still stay strong in today's modernised Seiko 5 Sports designs. The bi-colour 24-hour bezel is coated in Hardlex, to ensure durability while the GMT hand improves practicality, visibility and legibility. The Jubilee bracelet remains true to the SKX heritage with a 'five-row’ design that contrasts with polished middle rows and solid outer rows that unite. Designed for practical international timekeeping, the GMT hand and high visibility hour markers, along with clear 24-hour bezel, mean multiple time zone calculations can be made at a glance, quickly and easily. The hands and indices are coated in LumiBrite - fluorescent luminous paint which quickly absorbs light energy, glowing brighter and longer in partial light. LumiBrite starts glowing brightly in the dark and fades slowly. 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
