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.

Yema Superman Slim CMM.20

Owners and reviewers praise the Yema Superman Slim CMM.20 for its appealing retro design, balanced 39mm case, and in-house CMM.20 micro-rotor movement, with some finding the fish scale bracelet attractive. Concerns exist regarding its $2500/€2,490 MSRP, with some owners questioning its value and noting the potential for QC issues or a "jittery" seconds hand attributed to the new movement. The bracelet's articulation and stamped clasp draw criticism, though some owners report it improves with wear. Overall, owners and reviewers appreciate the Yema Superman Slim CMM.20's vintage styling and unique micro-rotor movement, but its value proposition and some finishing details are points of contention.
