What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Fortis Flieger F-43 Triple-GMT

The Fortis Flieger F-43 Triple-GMT is widely praised for its stunning dial execution, COSC-certified Kenissi WERK 13 movement with a 70-hour power reserve, and legible Brixtrack luminous indices. Owners and reviewers highlight the surprisingly wearable 43mm titanium case and bracelet, noting its lightness and comfort despite the size, with one source specifically mentioning a quick-adjustable extension. The watch offers 200m water resistance and features a Synchroline indicator. However, some owners note the titanium scratches easily and the bracelet can be difficult to size. The watch is priced at €4,500. On balance, owners and reviewers rate the Fortis Flieger F-43 Triple-GMT highly for its purpose-focused pilot's watch design and innovative movement.

Marathon GPQ (General Purpose Quartz) Field Watch

Owners widely praise the Marathon GPQ (General Purpose Quartz) Field Watch for its rugged quartz movement, accuracy, and tritium lume. Reviewers and owners alike highlight its solid build, legibility, and comfortable, lightweight wear, making it particularly well-suited for smaller wrists. Some owners, however, consider the price point of $350-420 to be somewhat high. On balance, the consensus is that owners rate the Marathon GPQ (General Purpose Quartz) Field Watch highly for its dependable quartz accuracy and excellent tritium lume.
