Seiko Prospex Alpinist ‘Classic Pine’

Rooted in Seiko’s enduring heritage of exploration, the Seiko Prospex Alpinist SPB507J1 pays homage to the original 1959 design created for Japan’s ‘Yama-otoko’ mountain men. Built for resilience and refinement, this timepiece embodies both the spirit of adventure and Seiko’s renowned craftsmanship.

The classic pine green dial glows beneath durable sapphire crystal glass, its rich tone offset by cathedral-style hands and elegant Arabic numerals, evoking the charm of mid-century mountaineering watches. The polished stainless steel case bears a super-hard coating for superior scratch resistance and long-lasting brilliance, while the traditional ‘Mountain Device’ emblem on the case back recalls the watch’s rugged origins.

Through the exhibition case back, the automatic 6R55 calibre movement reveals its intricate mechanics, offering a 72-hour power reserve and accuracy of -15/+25 seconds per day. The Seiko Prospex Alpinist SPB507J1 is made for those who value endurance, precision, and timeless style, wherever their journey leads.
