The Seiko Prospex Sumo GMT is a 45mm stainless-steel dive watch with 200m water resistance, a solar quartz movement and a fourth GMT hand for tracking a second time zone. It replaces the mechanical Sumo's automatic movement with light-charged quartz, so it never needs a battery change and keeps better time, but it loses the sweeping seconds hand and mechanical character some enthusiasts want. The blue dial, strong lume and chunky case make it a legible, rugged daily wearer for divers and travelers. Against Swiss GMT divers it offers comparable water resistance and solar convenience for far less, though the 45mm case and thick profile wear large on smaller wrists.

Owners rate it very highly, praising the solar convenience, the legible blue dial and the solid Sumo build. The main complaints are the large 45mm case and the step down from the mechanical Sumo's automatic movement.
