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.

Hamilton Khaki Field Mechanical Power Reserve

The Hamilton Khaki Field Mechanical Power Reserve is noted for its 40mm sandblasted case, filling a size gap in the Khaki Field line. It features a new H-23 hand-wound movement with an 80-hour power reserve and a functional power reserve indicator at 9 o'clock. The case is 11.95mm thick, which is described as noticeably thicker than other Khaki Field models, and its proportions differ from classic manual-wind versions. The movement includes a slipping spring to resynchronize the power reserve indicator after shocks. Overall, reviewers appreciate the addition of the power reserve complication to the hand-wound model, though one reviewer noted a preference for a contrasting color on the indicator.
