This new model builds upon the original Landmaster design concept with modernised high performance in any land environment. Following feedback from adventurers, the watch case and bracelet are made from lightweight titanium which is super hard-coated, making it scratch-resistant with a beautiful shine.

The rotating bezel offers a compass functionality, a signature feature of the original Landmaster series. Powered by the reliable and highly accurate in-house 8L35 calibre movement, for high visibility the indices are coated with three-dimensional Lumibrite and the super hard-coated Sapphire glass eliminates 99% of reflections whilst having a special ‘stay clean’ feature.

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.
