SPB155J1

Description

The Seiko Prospex Alpinist SPB155J1 elegantly bridges rugged outdoor heritage with refined everyday wear. The watch features a 38.0 mm stainless steel case with a 12.9 mm thickness and 46.0 mm lug-to-lug, striking a balance between a solid wrist presence and comfortable wear. Its curved sapphire crystal with inner anti-reflective coating protects a rich green dial that evokes forested mountain landscapes, paired with bold hands and luminous indices for excellent readability day or night. 

Inside, the watch runs on the in-house Seiko 6R35 automatic movement with manual winding capability and a 70-hour power reserve. The movement delivers robust performance, supported by a screw-down crown and see-through screw case back for added protection and visibility of the mechanism. Water resistance of 20 bar (200 m) and LumiBrite on hands and indices ensure reliability on hikes, swims, or daily wear. 

With its blend of vintage-inspired design, modern materials, and durable construction, the Alpinist SPB155J1 remains one of Seiko’s most versatile pieces—suited equally for outdoor adventure, urban exploration, and classic everyday style.
