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 JDD (Jumbo Day/Date) Anthracite Diver's Automatic

Owners widely praise the Marathon JDD (Jumbo Day/Date) Anthracite Diver's Automatic as a tough, underrated tool watch with lifestyle appeal, highlighting its robust build and tritium lume for excellent legibility. However, its 46mm size is a common criticism, with some finding it heavy and top-heavy, and the OEM rubber strap stiff. One owner noted the watch runs about 10 seconds fast after three days, and the ETA 2836-2 movement offers approximately two days of power reserve. On balance, owners and reviewers rate the Marathon JDD (Jumbo Day/Date) Anthracite Diver's Automatic highly for its robust tool-watch build and legibility, despite its substantial size.
