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 C60 Sapphire Edge

Owners widely praise the Christopher Ward C60 Sapphire Edge for its innovative deep blue sapphire dial, which is considered superior to other transparent dial executions, and its slim, ergonomic 42mm case. The lumed rubber strap is also a frequently highlighted feature, contributing to the watch's homogeneous luminosity and "damn cool" aesthetic. The watch is noted for offering incredible value, with a Sellita SW300-1 movement providing a 56-hour power reserve and 60ATM water resistance. However, one owner reported the sapphire dial cracked from the inside during regular use, and the brand denied warranty repair for this issue. Overall, owners and reviewers rate the Christopher Ward C60 Sapphire Edge highly for its striking dial execution and innovative features at its price point.

Sinn U18

The Sinn U18 is praised for its unique deep blue/green dial with three-dimensional oxygen bubbles that change with light, and its comfortable, easily adjustable bracelet. Owners find the watch stunning and a piece of history, appreciating the refined hands. The Sinn U18 features a 44mm, 15.5mm thick case made from German submarine steel, offering a 2000-meter dive specification and Sinn's Ar-Dehumidifying technology, powered by a Sellita SW300-1 movement. The case thickness is apparent, and the watch comes as a complete set with box and papers for $3,000-$3,680. On balance, owners and reviewers rate the Sinn U18 highly for its striking dial and robust build.
