The Seiko 5 Sports SKX GMT “Mocha” marks a new chapter in Seiko’s iconic sports line — the first GMT model within the Specialist Style series. Combining bold design with practical functionality, it brings modern travel-ready capability to the beloved SKX silhouette.
Featuring a black dial and two-tone black-and-brown bezel accented with gold plating, this watch offers both warmth and sophistication. The GMT hand enables quick dual-time tracking, while LumiBrite-coated hands and markers ensure visibility in any light. Built from stainless steel and fitted with a brown calf leather strap, the watch delivers refined style without sacrificing Seiko’s signature durability.
