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.

Marathon Jeep Rubicon TSAR

Marathon Jeep Rubicon TSAR owners praise its toughness and 41mm size for a 7" wrist, noting the sapphire crystal remains nearly flawless after a decade of near-daily wear and abuse. Tritium lume is still acceptable in darkness, and the bezel, though missing its 0-mark triangle, remains tight and clicks solidly. The watch features a steel case water-resistant to 300 meters, a Sellita SW200-1 automatic movement, and dual branding that de-emphasizes Marathon. Overall, owners rate the Marathon Jeep Rubicon TSAR highly for its exceptional durability and practical size.
