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 C63 True GMT

The Christopher Ward C63 True GMT is widely praised for its in-house CW-002 caliber, which offers a 120-hour power reserve and COSC certification. Owners find the 39mm case size comfortable, though some note it wears closer to 40-41mm. While the PVD hands provide good contrast and the lume is praised for readability, one owner felt the orange accent lacked pop and the gloss dial/text combo appeared cheap in certain lighting. One owner also noted a perceived slight difference in production quality compared to a sibling model's bracelet. Overall, owners and reviewers rate the Christopher Ward C63 True GMT highly for its impressive power reserve and COSC-certified movement at its price point.

From video reviewers

The case finishing is praised for its polished and curved surfaces. The watch uses a Sellita SW330-2 movement. Reviewers disagree on the case size, with one noting 40.5mm and another highlighting a 36mm option.

Hamilton Khaki Aviation Converter Auto Chrono

The Hamilton Khaki Aviation Converter Auto Chrono is widely described as a large 44mm pilot's watch with a functional slide rule bezel. Reviewers note its well-finished steel case, featuring a robust satin-brushed finish with polished accents and chamfers, and a legible blue sunray dial with applied Super-LumiNova markers and old-fashioned hands. It is powered by the H-21-Si automatic chronograph movement, an upgraded ETA-based caliber with a silicon balance spring for anti-magnetic properties, offering a 60-hour power reserve. The watch is rated to 100m water resistance and features a bi-directional slide rule bezel with graduations printed under K1 mineral glass for scratch protection, which is easy to manipulate due to its deeply notched steel design. Some find the slide rule bezel complicated to use without a manual. One owner notes its character does not appeal as much as other slide bezel chronos.
