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.

Seiko 5 Sports SKX series

The Seiko 5 Sports SKX series is widely praised for its value, robust build, and powerful lume, with owners appreciating its comfortable bracelets and improved movement featuring hacking and hand-winding. Some owners find the original SKX models heavy and bulky, while others praise their ruggedness and iconic dive watch design. Reviewers note the 38mm models offer great value at around €350 and are exemplary gateway watches, though their 100m water resistance without a screw-down crown makes them unsuitable for diving. The Seiko 5 Sports SKX series is seen as a decent watch, especially under £200, but lacks the tool watch capabilities of the original SKX, missing a screw-down crown, bezel pip, and ISO rating. On balance, owners and reviewers rate the Seiko 5 Sports SKX series well for its blend of value, improved movement, and tool-watch aesthetic, despite some missing dive certifications.
