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 Colchester

The Christopher Ward C63 Colchester is praised for its extremely lightweight, 41mm forged carbon case and dial, weighing only 38 grams, and its COSC-certified Sellita SW200 movement. Some owners report the lume lasts all night, while others note the red seconds hand can be difficult to see in low light. The recessed crown is a point of discussion, with one owner finding it difficult to manipulate due to its thinness and another suggesting it may be gimmicky. The watch is offered at $925. Overall, owners appreciate the unique materials and lightweight design of the Christopher Ward C63 Colchester, though some express concerns about the crown functionality and price point.

Seestern S450 Ocean Star

Owners widely praise the Seestern S450 Ocean Star's Yachtmaster-style case and flawless bracelet finishing, with one owner noting the ST2130 movement keeps good time. The bezel action is described as having individual notches but feeling like a friction bezel, while another owner flags the bezel and crown action as smooth with perfect alignment. Lume is a point of contention, with one source describing it as a nice cool blue with ice-white application, while others note it as weak or not matching Prospex standards, despite using BGW-9. The watch is considered a "big boy" ideal for larger wrists (19cm+), potentially too large for 17cm wrists due to its size and non-tapering bracelet. Overall, owners rate the Seestern S450 Ocean Star highly for its build quality and finishing at the price point, despite some reservations about its size and lume intensity.
