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 King Day-Date

Hamilton Khaki Field King Day-Date owners widely praise its classic styling, 80-hour power reserve, and excellent value. Opinions on water resistance are split; some express concern over the 50m rating, while others find it sufficient for daily wear and swimming. One owner notes the stock strap can be stiff. Service costs range from $55 for routine maintenance to $220 for full service with movement replacement. On balance, owners rate the Hamilton Khaki Field King Day-Date highly for its classic aesthetics and impressive power reserve at its price point.

From video reviewers

The 80-hour power reserve from the H-40 automatic movement is a significant strength. The 50-meter water resistance is considered a limitation for a field watch.
