Seiko Prospex Coastline Diver Watch, SPB485J1
Seiko Prospex Coastline Diver SPB485J1 Men's Watch with Black Dial and Brown Bezel
The Seiko Prospex Coastline Diver SPB485J1 combines the performance of a full-blooded diver's watch with a refined and unique appearance. The black dial, reminiscent of the undulating sea surface, gives the model a lively feel, while the copper-toned hands provide a warm contrast to the steel body. The polygonal bezel and polished surfaces create a sporty yet refined look. LumiBrite-coated hands, indexes and bezel ensure good readability even in low light and underwater.
Seiko's 6R55 caliber automatic movement with manual winding offers a power reserve of approximately 72 hours or up to three days, and a stop-second function. The nearly scratch-resistant sapphire crystal with anti-reflective coating improves visibility in bright light, and the screw-lock crown and 300-meter water resistance make this model truly suitable for diving. In line with the Prospex series, the structure is designed to withstand demanding use both in water and in everyday life.
Japanese Seiko watches are known for their technical excellence and durability. With over 100 years of history, Seiko has brought significant innovations to the watch industry, such as the first quartz watch and kinetic technology.
