What people say

Owners + reviewers, side by side

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

Christopher Ward C65 Aquitaine Bronze COSC

Owners widely praise the Christopher Ward C65 Aquitaine Bronze COSC for its comfortable wearability, durable case and bezel, and smooth winding action, with one owner finding its case superior to a Tudor's. However, accuracy is a significant concern, with one owner reporting +17 seconds per day. The rubber strap is also noted as lacking refinement, and some suggest design tweaks for greater brand uniqueness. Overall, owners rate the Christopher Ward C65 Aquitaine Bronze COSC highly for its wearability and case finishing, despite accuracy concerns with the Sellita SW330-2 movement.

Tudor Pelagos Ultra

The Tudor Pelagos Ultra is praised for its 1000 meters of water resistance, METAS-certified Calibre MT5612-U movement, and fully lumed dial and bezel. Reviewers highlight its titanium case and self-adjusting clasp as key features. The Tudor Pelagos Ultra is slightly larger at 43mm than some other models in the line but wears comfortably. Overall, owners and reviewers rate the Tudor Pelagos Ultra highly for its technical specifications and comfortable wearability as a flagship dive watch.

From video reviewers

The Tudor Pelagos Ultra's all-titanium construction provides a lightweight and durable case. One weakness is the lack of lume brightness. Reviewers disagree on whether the helium release valve is a notable feature or a drawback for a more streamlined design.
