Seiko Prospex Collection/ Sea Series
Japanese solar watch with a stainless steel bracelet strap, 45mm case, unidirectional rotating bezel, blue coloured dial & date window.

Seiko Prospex introduces its first solar watch with a GMT hand, powered by the in-house built new calibre of 5K62. The watch shape is affectionately named 'Sumo' by Seiko fans because of its size and shape and the 12 o'clock marker - it's a substantially strong looking timepiece. The Lumibrite colour on the 24-hour hand is high in visibility underwater and the aqua coloured dial produces vibrant accents to the elegantly pressed pattern design. The 200 metre water resistance is paired with a stainless steel case and high power generation efficiency.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.Since launching Japans first divers watch in 1965, Seikos innovative watchmaking has changed global dive watch standards.
