What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Marathon GPQ (General Purpose Quartz) Field Watch

Owners widely praise the Marathon GPQ (General Purpose Quartz) Field Watch for its rugged quartz movement, accuracy, and tritium lume. Reviewers and owners alike highlight its solid build, legibility, and comfortable, lightweight wear, making it particularly well-suited for smaller wrists. Some owners, however, consider the price point of $350-420 to be somewhat high. On balance, the consensus is that owners rate the Marathon GPQ (General Purpose Quartz) Field Watch highly for its dependable quartz accuracy and excellent tritium lume.

Phoibos Wave Master GMT

The Phoibos Wave Master GMT is widely praised for its attractive design, comfortable 20mm tapering bracelet, and wearability on a 7" wrist, with owners finding it a strong value proposition at $220. Some minor finishing flaws, such as slightly crooked markers and off-center dial numbers, are noted by one owner, while accuracy averages around 5-10 seconds over two weeks. Overall, owners rate the Phoibos Wave Master GMT highly for its distinctive design and comfortable wearability at its price point.

From video reviewers

The Wave Master GMT's notable feature is its 200M water resistance. A drawback is the rattle of the bracelet. Reviewers disagree on the watch's value, with one reviewer noting its significant weight for a 39.5mm case diameter, but the other reviewer doesn't mention any specific weaknesses or trade-offs.
