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 Day Date Auto

Owners widely praise the Hamilton Khaki Field Day Date Auto for its robust build, clear dial legibility, and versatility as a "go anywhere, do anything" watch, connecting them to a classic aesthetic and historical significance. Reviewers and owners alike highlight its value, with some noting the 80-hour power reserve from the H10 movement and 100m water resistance. However, some owners find its lume intensity and longevity inexcusable, and a common criticism of Hamilton watches is the lack of AR coating on the crystal. The bracelet finish and overall appearance are points of contention, with some considering it plain or overrated while others praise its finishing and attractive PVD. Accuracy ranges from excellent to simply "ok," with no consensus on movement quality. Overall, owners and reviewers rate the Hamilton Khaki Field Day Date Auto highly for its classic aesthetic, robust build, and value as an entry-level automatic field watch.

From video reviewers

The 80-hour power reserve from the H-40 movement is a significant strength. The 50-meter water resistance is considered limited for a field watch. Reviewers disagreed on the bracelet quality, with one noting rattle and another not mentioning it.
