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.

Sternglas Kanton

The Sternglas Kanton is praised for its refined Bauhaus-inspired design, featuring a silver-plated dial and luminous hands and dots for excellent legibility. Owners and reviewers highlight its comfortable 39mm case size, measuring 10mm thick, and the visible STP 1-11 automatic movement through a sapphire crystal case back. Accuracy figures vary, with one source noting +15 seconds per day, while another suggests improved accuracy over previous models. Overall, owners and reviewers rate the Sternglas Kanton highly for its blend of Bauhaus design and Swiss precision at an affordable price point.
