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.

Grand Seiko SLGH017

Grand Seiko SLGH017 owners and reviewers widely praise its impeccable finishing on the applied markers and handset, and its lightweight titanium case and bracelet. The high-beat 9SA5 movement is noted for its approximately 80-hour power reserve, with accuracy figures reported by owners ranging from +4 sec/day to +5 to -3 seconds per day, though some owners express concerns about accuracy deviating significantly from specifications. Some find the "Night Birch" dial stunning and appreciate the Evo 9 case design, while others note the dial texture appears less pronounced on its matte black surface and criticize the handset's proportions and lack of lume. The Grand Seiko SLGH017 is priced at €10,500. On balance, owners and reviewers rate the Grand Seiko SLGH017 highly for its lightweight titanium construction and impeccable finishing.
