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 Aviation Air Race Auto

Owners widely praise the Hamilton Khaki Aviation Air Race Auto for its legibility and practicality, with some appreciating its countdown bezel and GMT pointer. However, opinions on its design are split, with some calling it a "Frankenstein" and disliking the skeleton hands, while others find the hands suitable for a pilot watch. One owner notes the lume is underwhelming and the 44mm size may be too large for some wrists. The original strap is also described as uncomfortable and prone to water stains. On balance, owners value the Hamilton Khaki Aviation Air Race Auto for its legibility and practical features, despite a polarizing design and some comfort concerns.
