What people say

Owners + reviewers, side by side

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

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.

Undone Basecamp Cali Blue

The Undone Basecamp Cali Blue is praised for its attractive, vintage-feeling California dial and subtle texture, with owners appreciating the 40mm case fit and customization options. Reviewers note the desirable, affordable timepiece features a textured Cali dial and 100m water resistance. Some drawbacks mentioned include the lack of a date function and a 15mm thickness, exacerbated by a chunky strap. The watch is powered by a Seiko NH35 automatic movement and features a friction bezel. Overall, owners and reviewers rate the Undone Basecamp Cali Blue highly for its unique dial design and value.
