The Glycine Men's Combat Sub Sport GMT 42mm Automatic Watch GL0382 is praised by owners for its value, build quality, and reliable movement, with one owner finding its curved lugs wear well on a 7-inch wrist. Its lume lasts longer than a Seiko SKX007's, though the SKX's hour markers are more visible after 15 minutes. The bezel action is described as stiff and scratchy, yet also distinct and solid. One owner successfully replaced the date wheel for a different aesthetic. The Glycine Combat Sub 42mm GMT is seen as a good alternative for those seeking a Pelagos FXD, with dimensions of 42mm x 49.5mm x 10.5mm, and is considered its own design rather than an homage. Owners note that while often advertised over $1000, it can be found for around $300-$330. Overall, owners rate the Glycine Men's Combat Sub Sport GMT 42mm Automatic Watch GL0382 highly for its value and wearability on average wrists.
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.
