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 Trident GMT 300

Owners widely praise the Christopher Ward C60 Trident GMT 300's build quality and finishing, finding it a serious alternative to established Swiss brands. The 40mm size is considered comfortable with good wrist presence, and the lume is fantastic. The Sellita SW330-2 movement is noted as slim for a GMT, with one owner reporting accuracy of +5 seconds per week. Some owners dislike the older Bader bracelet and wish for better AR coating, while a reviewer noted the handset could be updated. On balance, owners and reviewers rate the Christopher Ward C60 Trident GMT 300 highly for its exceptional build quality and finishing at its price point.

Marathon JDD (Jumbo Day/Date) Anthracite Diver's Automatic

Owners widely praise the Marathon JDD (Jumbo Day/Date) Anthracite Diver's Automatic as a tough, underrated tool watch with lifestyle appeal, highlighting its robust build and tritium lume for excellent legibility. However, its 46mm size is a common criticism, with some finding it heavy and top-heavy, and the OEM rubber strap stiff. One owner noted the watch runs about 10 seconds fast after three days, and the ETA 2836-2 movement offers approximately two days of power reserve. On balance, owners and reviewers rate the Marathon JDD (Jumbo Day/Date) Anthracite Diver's Automatic highly for its robust tool-watch build and legibility, despite its substantial size.
