What people say

Owners + reviewers, side by side

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

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.

Tissot Seastar 1000 Powermatic 80 GMT

Owners widely praise the Tissot Seastar 1000 Powermatic 80 GMT for its excellent build quality, smooth winding feel, and the reliable Powermatic 80 movement providing an 80-hour power reserve. Reviewers highlight its remarkable value under $700, comfortable wearability, and appealing case/dial ratio. Some owners note the bezel's functionality for tracking a second time zone and the need to adjust the hour hand for date setting, a characteristic of its "True" GMT function. The rubber strap is considered comparable to those found on significantly more expensive watches. However, concerns exist regarding the movement's serviceability due to potential plastic components and reliance on Swatch Group service centers. Some find the bezel font and dial spacing unappealing, while others question the mineral glass bezel insert as a cost-cutting measure compared to ceramic. Accuracy is generally reported as good, though not COSC certified, and lume intensity is described as average by one owner.
