What people say

Owners + reviewers, side by side

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

Bremont Altitude Perpetual Calendar GMT

The Bremont Altitude Perpetual Calendar GMT is a highly exclusive piece, with one owner noting its $44,000 price point raises questions about its target audience and suggesting it may be a limited production showpiece. Reviewers highlight its refined Trip-Tick case, now featuring softer curves, a 42mm diameter, and a 12.23mm thickness in grade 2 titanium, though the oversized crowns are flagged as a potential drawback. Overall, owners and reviewers acknowledge the Bremont Altitude Perpetual Calendar GMT as a distinctive, albeit niche, high-complication offering with a notable case refinement.

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.
