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

Owners widely praise the Phoibos Wave Master for its attractive wavy dial, bright lume, and comfortable engineer bracelet, with many considering it one of the best-looking watches under $300. The watch features a sapphire crystal and ceramic bezel, and owners report good quality for the price, with a subtle wave pattern on the dial appreciated for its unique style. While some minor finishing flaws like slightly crooked hour markers or an off-center outer ring have been noted, these are generally considered not visible during wear. One owner experienced a clasp breakage after four years, but Phoibos replaced it free of charge. Some owners wish the watch were larger than 40mm, and one notes the GMT hand and other details may not hold up under extreme close-ups. Overall, owners rate the Phoibos Wave Master highly for its distinctive dial and value, especially considering its build quality and features.

From video reviewers

The unidirectional ceramic bezel action is praised. The lume brightness is noted as a weakness. Reviewers disagree on the water resistance rating, with some stating 300M and others 200M.
