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.

One owner finds the 41mm case runs a bit small. The Marathon Steel Navigator SSNAV Auto utilizes an ETA F06.412 quartz movement with a claimed accuracy of +/- 10 seconds per year and includes a GMT bidirectional bezel.
