Product Description :
Taking its name from the original and much-loved Seiko ‘Alpinist’ – launched in 1959 for Japanese ‘Yama-otoko’ mountain men, reliable in treacherous terrain – this watch further evolves the Alpinist specifications and overall design – with a legibility focus.
Its Arabic numerals are a signature feature of Alpinist pieces, whilst the curved sapphire glass, 24-hour display on the bezel and red 24-hour hand enhance the legibility further.
Ever practical, the watch features a compass functionality, whilst its super-hard coating gives it shine and strong scratch resistance. The in-house built 6R54 Calibre is the first mechanical GMT movement in a Prospex watch to have a three-day power reserve, allowing tracking of two different time zones at the same time.
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.
