Owners report the Glycine Men's Combat Sub Sport GMT Bronze 42mm Automatic Watch GL0319 runs well and accurately, with one owner noting it survived range trips, diving, and drops. The bronze case is patinating less than expected for some, despite ocean exposure. One owner finds the 42mm case size large on their wrist, while another describes the watch's dimensions as 42mm x 49.5mm x 10.5mm and a unique design. A caveat mentioned is sub-par lume, described as pretty but difficult to read at night, and an inconsistent power reserve. Overall, owners rate the Glycine Men's Combat Sub Sport GMT Bronze 42mm Automatic Watch GL0319 well for its robust performance and unique design, despite some reservations about lume and case sizing.
The Seiko Prospex Sea 1968 Heritage Diver's GMT is widely praised for its build quality, finishing, and value, with owners noting its comfortable wearability and attractive aesthetic, particularly the silver/white sunray dial and blue ceramic bezel. The improved bracelet clasp with excellent micro-adjustment is a recurring positive point. Some owners report accuracy figures of +3 seconds per day or +/- 5 seconds per day, exceeding the movement's stated range. However, the GMT functionality is considered secondary to its dive watch capabilities by some, with the GMT scale being difficult to read and the caller-style GMT movement being a drawback for certain users. The dial contrast is also noted as lacking by some, and the crown at 4 o'clock is undesirable for a few. On balance, owners and reviewers rate the Seiko Prospex Sea 1968 Heritage Diver's GMT highly for its blend of dive watch character and GMT functionality, offering significant features for its price.
