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 S456 GMT

Owners widely praise the Seestern S456 GMT for its exceptional value and finishing that exceeds expectations, with one owner noting its accuracy surpasses that of their Seiko 5. The dial displays a pearl-like rainbow effect. Some owners would prefer a bidirectional bezel over the current unidirectional one. The Seestern S456 GMT features an NH34 movement, a 39.5mm case, sapphire crystal, and an adjustable clasp. On balance, owners rate the Seestern S456 GMT highly for its impressive finishing and value proposition at its price point.
