Seiko ventures into new (and much requested) territory this week with the release of a new collection of GMT divers within their Prospex family. Using their modern 6159 design language seen in watches like the SPB187 with MM200 roots, the new watches strike a fine balance between their roots, and a strong contemporary vision for the range. Seiko has proven quite adept at this in recent years with their restructuring of their dive watch collections, but these latest examples bring something new to the table: a GMT complication within a new 3 day automatic movement, the 6R54.
The new Prospex GMT diver range welcomes two new references in the SPB381 and 383, and in true Seiko fashion, a single limited edition in the SPB385. Each welcomes the new 6R35 within a steel 42mm case that measures 12.8mm in thickness, and should wear quite similarly to this SPB187 we went hands-on with right here. The angular case gets the distinctive deep chamfer along the lug which has a relatively short overhang to make for a perfectly manageable experience on the wrist.
