What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

CWC 6BB-WR

The CWC 6BB-WR is widely praised for its legible matte black dial, strong lume, and crisp chronograph operation. Owners and reviewers note its military heritage and rugged, confidence-inspiring build with a screw-down crown and pushers. The Sellita SW510 BH b automatic movement kept time within COSC range in testing. However, its 14.9mm thickness and 80g weight make it wear large, and the cam-lever movement lacks the satisfying click of a column wheel. Fixed bars limit strap options. On balance, owners and reviewers rate the CWC 6BB-WR highly for its legible dial and robust pilot chronograph design at its price point.

Seiko 5 Sports SKX series

The Seiko 5 Sports SKX series is widely praised for its value, robust build, and powerful lume, with owners appreciating its comfortable bracelets and improved movement featuring hacking and hand-winding. Some owners find the original SKX models heavy and bulky, while others praise their ruggedness and iconic dive watch design. Reviewers note the 38mm models offer great value at around €350 and are exemplary gateway watches, though their 100m water resistance without a screw-down crown makes them unsuitable for diving. The Seiko 5 Sports SKX series is seen as a decent watch, especially under £200, but lacks the tool watch capabilities of the original SKX, missing a screw-down crown, bezel pip, and ISO rating. On balance, owners and reviewers rate the Seiko 5 Sports SKX series well for its blend of value, improved movement, and tool-watch aesthetic, despite some missing dive certifications.
