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.

Gruppo Gamma Field III GMT

Owners praise the Gruppo Gamma Field III GMT for its look and value, with specific mentions of its sandwich dial and comfortable OEM straps. One owner notes incredible quality for the price across their Gruppo Gamma watches. The watch features a 40mm brushed stainless steel case, box sapphire crystal, and a Seiko NH34A movement with a 41-hour power reserve and stated accuracy of -20~+40 s/day. Some find the lack of a date window a drawback for a GMT, and question its differentiation from other NH34-powered watches. On balance, owners and reviewers find the Gruppo Gamma Field III GMT to be a good value with quality construction for its price point.
