The Seiko 5 Sports X Rowing Blazers line was introduced in 2021. Designed in collaboration with Jack Carlson of Rowing Blazers, the line includes three unique bezel designs inspired by the fashion company Rowing Blazers. Based on the Seiko 5 Sports watch, the SRPG51 features the automatic in-house Caliber 4R36 movement, visible through the exhibition case back with the “memento mori” skeleton motif on the crystal.
