Seiko Prospex Alpinist — Four Fresh Additions
What’s New
Movement Upgrade
The SPB503J1, SPB505J1 and SPB507J1 now run on the Calibre 6R55 — a newer automatic movement offering a 72-hour power reserve and a display caseback. A solid upgrade for those who appreciate weekend-spanning autonomy.
Dial Choices
The trio introduces three distinct personalities: a cool teal-blue dial, a crisp black option and a deep forest-green version paired with a brown leather strap. Each remains unmistakably Alpinist with their clean layout and internal rotating compass bezel.
Case and Build
All three models continue with the familiar compact case size of just under 40 mm, complete with sapphire crystal, screw-down crown and the rugged dependability that’s defined the Alpinist name for decades.
European Exclusive
The SPB531J1 steps in as the special release — a limited European edition featuring a rich blue dial and a pair of interchangeable straps. It keeps the trusted 6R35 movement with its 70-hour reserve and leans into versatility with a mix of sporty and classic styling.
Heritage Meets Everyday Toughness
These releases continue Seiko’s formula: vintage Alpinist DNA blended with modern practicality. They’re compact, capable and stylish enough for everyday wear — whether you’re scaling a ridge or just trekking through the morning commute.
