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 C1 Jump Hour Mk V

Owners and reviewers widely praise the spectacular lume application and the multi-level dial design of the Christopher Ward C1 Jump Hour Mk V, noting its crisp legibility and the innovative JJ01 jump-hour module. The 39mm case is described as compact with alternating brushed and polished finishing, and the dial features a radially grooved center with a sapphire minute track. Some find the 14mm thickness and $3k price point high, while accuracy is rated at approximately ±20 seconds per day. The watch utilizes a Sellita SW200-1 base with a 38-hour power reserve. Overall, owners and reviewers appreciate the striking dial design and jump-hour complication, despite some reservations about the thickness and accuracy.

Spinnaker Bradner GMT

The Spinnaker Bradner GMT is praised for its awesome lume and comfortable wearability, with one owner noting the rubber strap is very comfortable and the beads of rice bracelet fits well on smaller wrists. Some find its 15mm thickness and bold colorway may not appeal to everyone, and one owner views it as more of a casual GMT with tool-watch styling than a diver. Overall, owners rate the Spinnaker Bradner GMT highly for its value and comfortable wearability.
