What people say

Owners + reviewers, side by side

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

Alexander James Watches A3 Omen

Owners widely praise the Alexander James Watches A3 for its exceptional value, with one owner calling the $75 price a steal, especially with a gold milanese bracelet. The dial's ability to shift appearance under different lighting conditions is a frequently admired trait, and the BGW9 Superluminova is described as great, though not the brightest. One owner noted the 39mm case diameter and 20mm lug width. Overall, owners rate the Alexander James Watches A3 highly for its striking dial and remarkable value proposition.

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.
