What people say

Owners + reviewers, side by side

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

Maen Grand Tonneau Ultra Thin

Owners widely report the Maen Grand Tonneau Ultra Thin features a La Joux-Perret D101 manual-wind movement and a double-layer enamel dial. Some owners criticize the bracelet design and find the dial too small and lacking indices. One owner describes the Maen Grand Tonneau Ultra Thin as "hideous with a good movement." On balance, owners are divided on the Maen Grand Tonneau Ultra Thin, with some appreciating its movement and dial while others find its design unappealing.

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.
