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 Naos XS

Owners widely praise the Sternglas Naos XS for its simple, awesome design, domed sapphire crystal, and clean hands, with one owner highlighting the beautiful blue mother-of-pearl dial and top-notch build quality on a special edition. It is recommended as a durable, refined daily wear watch for around $270, suitable for casual and formal occasions. However, one owner found the Sternglas Naos XS to have a cheap feel and a face resembling a toy, noting it wears smaller than expected, while another described the automatic movement as a bit noisy. On balance, owners rate the Sternglas Naos XS highly for its refined design and value, with specific praise for the mother-of-pearl dial on special editions.
