What people say

Owners + reviewers, side by side

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

Oris ProPilot X Calibre 400 Laser

The Oris ProPilot X Calibre 400 Laser is praised for its high-tech laser-etched titanium dial and the advanced Calibre 400 movement with a 120-hour power reserve. However, the dial's unique rainbow gradient is polarizing, with one owner finding it childish and preferring applied indices for better legibility and lume, while reviewers note the case shape may still require adjustment. The CHF 4,800 price is also flagged as steep for a time-only watch. On balance, owners and reviewers acknowledge the innovative dial and movement, but opinions are divided on its aesthetic appeal 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.
