What people say

Owners + reviewers, side by side

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

Formex Field Automatic

Owners widely praise the Formex Field Automatic for its lightweight, scratch-resistant Grade 2 titanium case with a hardening treatment and its comfortable wearability, especially with quick-release straps and a carbon clasp. Reviewers and owners alike highlight the dial's legibility and depth, with one noting the Petrol Blue's great color and subtle texture. The Sellita SW200-1 movement is considered a practical choice, with one owner reporting accuracy of +1 second per day. The watch offers 150m water resistance and is seen as good value under $1000. Some owners desire a matching titanium bracelet and find the numeral typography less appealing. Overall, owners and reviewers rate the Formex Field Automatic highly for its robust, comfortable titanium construction and functional dial 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.
