What people say

Owners + reviewers, side by side

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

Brillier GMT (DUAL TIME) Mechanical Automatic Round 38 mm Gold Case Black Face

The Brillier GMT (DUAL TIME) Mechanical Automatic Round 38 mm Gold Case Black Face earns strong owner appreciation for its dual-time functionality and clean dial design without a date window. The black dial is particularly praised for its depth and presence in person. Owners appreciate the asymmetrical 4 o'clock pusher as part of the design language, though one notes a preference for a thinner case profile. Overall, owners rate the GMT highly for its functional dual-time complication and striking black dial execution 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.
