The Seiko Prospex "Alpinist" SPB121 has a design you're probably already familiar with. The green dial with gold accents seen here is directly influenced by the cult classic SARB017, which was the most popular design from the previous Alpinist generation, released in 2006. The SARB017 was the watch that spawned the Alpinist’s modern resurgence due to its distinct, maximalist flair.
