Seiko Mens Prospex Alpinist 'Summit Black' Automatic Bracelet Watch SPB505J1

Celebrating Seiko’s enduring heritage of exploration, the Seiko Prospex Alpinist SPB505J1 draws inspiration from the original 1959 design created for Japan’s ‘Yama-otoko’ mountain men. Built to withstand challenging environments while retaining a refined aesthetic, this timepiece embodies precision and resilience in equal measure. Beneath the sapphire crystal glass lies a deep black dial adorned with cathedral-style hands, Arabic numerals and wedge-shaped indices, a faithful nod to the early Laurel Alpinist. The traditional Alpinist emblem sits proudly beneath the Seiko logo, while the ‘Mountain Device’ motif on the case back reinforces its adventurous legacy. The stainless steel case features Seiko’s super-hard coating, offering both scratch resistance and an elegant lustre. Visible through the exhibition case back, the in-house automatic 6R55 calibre delivers dependable performance with a 72-hour power reserve and accuracy of -15/+25 seconds per day.
