SEIKO Prospex Alpinist Automatic Watch - SPB503J1

From the Alpinist collection, first launched in 1959, these watches were designed for Japanese 'Yama-otoko' mountain men, to be reliable in treacherous terrain. Under the sapphire crystal glass, the archive-inspired teal blue dial is complemented by 'cathedral style' hour and minute hands, accompanied by classic Arabic numerals and wedge-shaped indices. It features the traditional Alpinist logo under the Seiko logo, which featured on the very first 1950s Laurel Alpinist. The 'Mountain Device' logo features on the caseback of these watches, an aspect of the vintage original indicating the field nature of the watch. The case has an applied super-hard coating for increased scratch resistance and shine. Through the exhibition case back, the in-house automatic 6R55 calibre can be viewed, accurate to -15/+25 seconds per day, with a power reserve of 72 hours. 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.
