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 Narwhal

Owners widely praise the Phoibos Narwhal's 38mm size and slim 11.5mm height for a 200m diver, noting it wears well on smaller wrists and its case shape resembles an integrated bracelet. The aventurine and Howlite dials are described as captivating, and some appreciate the contrast finishing and retro looks. However, some owners criticize misaligned markers and a tilted date window, with one owner finding the hands thick and popsicle-style. The value proposition is debated, with some finding it a good buy at $390 but others considering $480-$490 too much due to a slabby design and difficult-to-size bracelet. On balance, owners find the Phoibos Narwhal appealing for its design and wearability, though quality control and pricing are points of contention for some.

From video reviewers

The unique stone dial is a significant strength. The bracelet's refinement is a weakness. Reviewers disagree on the dial's appeal, with one highlighting its sunburst effect and applied indices, while another focuses on the natural stone variation.
