The Heritage Behind the Alpinist

The Alpinist collection traces its roots back to 1959 when Seiko introduced a watch specifically designed for Japanese mountain climbers. Unlike traditional dive watches, the Alpinist was engineered for exploration on land, making it one of the most unique sports watches in Seiko's history.

The SPB117 continues this legacy while incorporating modern upgrades such as a sapphire crystal, enhanced water resistance, and the dependable 6R35 automatic movement.

Distinctive Design and Dial Features

One of the most recognizable aspects of the SPB117 is its black dial paired with highly legible shark-tooth style hour markers. The combination of cathedral hands, luminous indices, and the signature dual-crown configuration creates a look that stands apart from virtually every other sports watch in its category.

The second crown controls the internal rotating compass bezel, a hallmark feature that has become synonymous with the Alpinist collection.

Powered by the Reliable 6R35 Automatic Movement

Inside the SPB117 beats Seiko's in-house Caliber 6R35 automatic movement. This modern caliber delivers approximately 70 hours of power reserve, allowing the watch to continue running for nearly three days when not worn.

Additional features include:

• Automatic and manual winding capability
• 70-hour power reserve
• Hacking seconds
• 24 jewels
• Reliable daily performance

Built for Adventure

True to its name, the Alpinist was designed for outdoor enthusiasts. The internal compass bezel can be used for directional navigation when combined with the position of the sun, making it a practical tool for hikers and explorers.

With 200 meters of water resistance, a screw-down crown, and durable stainless steel construction, the SPB117 is prepared for both wilderness adventures and everyday wear.
