What people say

Owners + reviewers, side by side

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

AVI-8 Spitfire Lock Chronograph

Owners widely report AVI-8 watches offer a compelling design and are decently well made for the price. The AVI-8 Spitfire Lock Chronograph features a 42mm stainless steel case with curved lugs, a bi-compax meca-quartz movement, and a mineral crystal, with design elements inspired by Supermarine Spitfires. One owner notes that AVI-8 watches are "something different" and "decently well made," though not of "insane quality." On balance, owners and reviewers appreciate the AVI-8 Spitfire Lock Chronograph for its unique design and value proposition.

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.
