What people say

Owners + reviewers, side by side

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

Hamilton Khaki Navy Scuba Auto

Owners and reviewers widely praise the Hamilton Khaki Navy Scuba Auto for its exceptional value, robust construction, and distinctive dial designs, with many highlighting the 80-hour power reserve provided by the H-10 movement. The watch is frequently noted for its utilitarian dial, legible lume, and tactile bezel action. However, the 43mm case size is a recurring point of contention, with several sources deeming it large for everyday wear, though some owners find it comfortable and appreciate its substantial feel. One reviewer points out that the steel bracelet could benefit from a taper and a quick-adjust clasp, and another notes the unlumed bezel pip as a minor area for improvement. Overall, the Hamilton Khaki Navy Scuba Auto is highly regarded by owners and reviewers for its strong value and appealing tool-watch aesthetic, with the 43mm case size being the most significant consideration for potential buyers.

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.
