Prospex 'Navigator Timer'Limited Edition Mechanical GMTThis model is limited to 4, 000 pieces worldwide and is a recreation of the Navigator Timer launched in Japan in 1968. The Navigator Timer was a pioneer in the realm of sports-type GMT models, being the first mechanical GMT watch with a rotating bezel. Benefiting from over 110 years of Seiko’s watchmaking expertise this modern watch is powered by the new in-house Calibre 6R54, the first mechanical GMT movement for Seiko Prospex with a three-day power reserve. The case size and case back layout mimics the look of its original inspiration, whilst the super hard coating gives scratch resistance with a long-lasting shine. The GMT function allows the wearer to conveniently track two different time zones at the same time. Equipped with an ultra-scratch resistant sapphire crystal glass, it also has an anti-reflective coating on the inner surface to help showcase more clearly the highly detailed dial. With hour marker indexes that are now embossed into the dial rather than glued into place, any possible future failure here is eliminated, further ensuring your Seiko watch will retain its beauty and performance for the long term for which the brand is proudly recognised for. 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. Built to last and backed by Seiko’s trusted global service centre network with a 2-year guarantee, this watch will provide a lifetime of reliable service and pleasure for the owner.
