The Seiko Alpinist is a fan favorite that enthusiasts love for its classic, fairly compact design, its durability, and its affordability. Launched in 1959 with a screw back to prevent the intrusion of dust or sand particles, the very first Alpinist came on a bund strap that offered further protection from perspiration (plus a comfortable wearing experience). The watch you see here, all 36.6mm of it, is a tribute to the 1959 original, which was the Seiko Laurel Alpinist.
