Christopher Ward C1 Jump Hour Mk VvsYema Navygraf CMM.10

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.

Owners widely report quality control concerns and suspect craftsmanship with the Yema Navygraf, with one user noting crooked text. A reviewer praised the Slim CMM.20 Limited Edition for its stylish, slim profile and classy finishing on a black lacquered enamel dial, though the audible micro-rotor spinning at its price point was a surprise. On balance, the consensus is that while the Yema Navygraf offers a stylish design, potential buyers should be aware of reported quality control issues.
