Seiko Watch Prospex 300m Automatic Polygonal Divers Coastline Cobalt SPB483J1. Seiko Prospex 300m Automatic Polygonal Diver's in Coastline-cobalt

This timepiece combines the qualities of a Sports watch with the elegance of a dress watch.
Under a scratch-resistant sapphire crystal glass is a cobalt blue dial with a calm coastline pattern. The blue polygonal-style bezel with gentle curves not only give a modern aesthetic edge, but is also designed for a functionally enhanced grip - making turning the bezel quick and comfortable.

The hands and indices are strongly coated in Lumibrite for high visibility in dark conditions, whilst the case has a super-hard coating for high scratch resistance; the mirror-finished surfaces on the case providing its elegant sheen. Conforming to professional ISO diving specifications, the watch is eminently versatile - suitable for both formal occasions and active wear.

This automatic mechanical timepiece is water-resistant up to 300 metres, powered by a reliable in-house 6R55 automatic movement, accurate to -15/ 25 seconds per day with a three-day power reserve.

Prospex is a combination of the words 'Professional' and 'Specifications.' Seiko Prospex timepieces are designed to be practical, reliable and durable; to meet the high standards required in extreme environments for sports lovers and adventure seekers alike.
