What people say

Owners + reviewers, side by side

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.
