Seiko Prospex Alpinist EU Exclusive Limited Edition SPB531

The mountains have always been part of this watch’s story. Now, the Alpinist returns in a new edition that pays tribute to the Matterhorn at night and brings its presence to life. Deep blue, striking and limited to Europe. A design that blends alpine heritage with a contemporary look. A new take on summit history.

Alpinist. A Watch Between Summit and City

What was once created for alpine adventures is now a timepiece for those who live life to the fullest. In nature as well as in the heart of the city. The new limited Alpinist SPB531J1 is a tribute to Seiko’s first sports watch from 1959, reimagined for modern explorers. Available exclusively in Europe.

Dark As the Night Above Zermatt

The color theme is inspired by the night sky over the Matterhorn. The deep blue dial with its fine vertical texture evokes the clarity of mountain nights. Silver-colored hands add elegant accents and glide across the dial like starlight. A harmonious interplay of nature and precision.

Adventure-ready. Elegantly Executed

The Alpinist stays true to its roots and remains as versatile as ever. Rugged enough for outdoor adventures and refined enough for everyday urban life. Inside, the automatic 6R35 movement delivers reliable performance with a power reserve of approximately 70 hours. Day after day.

A Change of Style at the Wrist

With two straps, one in navy blue calf leather and one in durable nylon, the Alpinist adapts to any look. A timepiece equally at home in the mountains and in the urban jungle.
