Seiko’s Alpinist watch was first introduced back in 1959 as a watch for becoming a reliable timepiece for Japanese mountain climbers and other sports enthusiasts. Since then, there’s been a total of ten generations of Alpinist models that have been introduced to this date.

A solid screw-down crown and screw in display case back ensure for superlative levels of dependability and performance. The choice of color used on the dial of the SPB210J1, refer as ‘Sunbeam Forest Green’, while using the same gold color to match nicely with the Arabic numerals and arrow hour markers. The factory strap that comes with the SPB210J1 is a brown calfskin leather featuring contrasting waxed stitching.

The design of the leather strap is similar from the 1959 original predecessor, which provides a homage as well as providing the watch with an authentic feel. Furthermore, a three-fold deployment clasp with push button release was used to securely fastens the strap around when worn on wrist. The movement used in the SPB210J1 is Seiko’s 6R35 caliber movement which offers an incredible 70 hour power reserve and an accuracy of +25 to -15 seconds per day. The movement type is automatic with manual winding. The movement consists of 24 jewels and offers a hacking function that allows the wearer to accurately set the time.

The Seiko Alpinist watch collection will remain as one of the most recognized series of watches. With its history, reputation, and praises from watch enthusiasts from around the world, the Seiko Alpinist watches are definitely worth picking up. The Seiko Prospex Alpinist SPB210J1 has really caught my attention since I don’t have a gold color watch in my collection. Perhaps I should make a suggestion to the team to design a full IP gold bracelet for the SPB210J1. What do you guys think? Any suggestions?
