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.

Sternglas Naos Pro GMT Automatik

Owners report the Sternglas Naos can feel underwhelming with a cheap feel and hands resembling office printer output, with some finding it wears smaller than expected and looks like a toy, though others appreciate its understated design. Reviewers highlight the Argo Automatic variant as a compelling sub-€400 mechanical watch with a colorful dial and practical date wheel, suitable for new collectors, featuring a 38mm case and a Miyota 8215 movement. On balance, the consensus is that the Sternglas Naos offers a mixed ownership experience, with its value proposition and entry-level appeal being its strongest points for some.

From video reviewers

The Sternglas Naos Pro GMT Automatik features a clean Bauhaus design that sets it apart from other GMT watches. A notable weakness is the watch's bezel action, which is not as smooth as some reviewers would have liked. Reviewers disagree on the watch's case size, with one reviewer stating it's slightly larger than the original Naos Automatic, while another reviewer doesn't mention this aspect at all.
