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 GSAR

The Marathon Jeep Rubicon GSAR is widely praised as a rugged, high-quality tool watch that successfully blends Jeep branding with Marathon's functional heritage, featuring a unique dial with tritium illumination and an automatic Sellita SW200-1 movement. Owners appreciate its satisfying bezel action and durable build, making it a reliable daily wear that pairs well with Jeep's rugged image. However, some find the Jeep logo to be corporate and out of place with Marathon's austere design ethos, while one owner notes that second-hand examples can show wear on the bezel. The watch is priced at $1,500 USD. Overall, owners and reviewers rate the Marathon Jeep Rubicon GSAR highly for its robust construction and distinctive tritium lume, which are considered its strongest assets.
