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.

Seiko Prospex Sea 1970 Heritage Diver's Save the Ocean Special Edition

The Seiko Prospex Sea 1970 Heritage Diver's Save the Ocean Special Edition is praised for its beautiful design and refinement over previous models, featuring vertically textured glacier-inspired dials. Owners, however, consider the €1500 RRP too high, suggesting a price closer to €900-€1000, noting the aluminum bezel insert instead of ceramic. Some owners report the 6R movement runs slow. On balance, owners find the Seiko Prospex Sea 1970 Heritage Diver's Save the Ocean Special Edition beautiful and a refinement, but the price and aluminum bezel are points of contention.
