SEIKO PROSPEX MM200 GMT - SPB381J1

First Mechanical Prospex Diver With GMT Function

With Seiko's 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 the 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.

These watches mark the first time a mechanical GMT movement has made its way into the Prospex dive watch, as the GMT diver is something of a niche genre, and may, to some extent, excuse the fact that this is a caller-style GMT execution. The GMT hand can be set independently in one-hour increments, making it a better option for those who work with or communicate with other time zones than for those who travel between them frequently.

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.
