What people say

Owners + reviewers, side by side

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

Fortis Novonaut N-42

Owners widely praise the Fortis B-42 Official Cosmonauts for its stunning fit and finish, excellent legibility, and a precise, grippy bezel, with one owner calling its bracelet the nicest they've ever owned. The Fortis Novonaut N-42 is described as a flawless beast with a WERK 17 column-wheel chronograph movement, featuring enhanced shock resistance and COSC adjustment, and is noted as a handsome tool watch with a beautiful dial and nice pusher action. However, the 42mm case of the B-42 wears larger than expected, and the Novonaut's 44mm case and chunky bracelet make it too large and heavy for many. The Fortis Titanium Legacy is a modern pilot's watch with a titanium case and bracelet, featuring a Kenissi WERK 13 movement with a 70-hour power reserve and three time zones. Overall, owners and reviewers highly regard the Fortis Titanium Legacy for its robust tool watch design and advanced movement technology, despite some concerns about case size and bracelet adjustability.

Sternglas Naos Solar

Owners widely praise the Sternglas Naos Solar for its elegant Bauhaus-inspired minimalist dial, slim profile, and value for money. The scratch-resistant curved sapphire crystal and functional date mechanism are noted as durable features, with one owner reporting good wear over a year. The solar power and accuracy are highlighted as practical advantages over automatic movements, which some find loud. However, opinions are split, with some owners finding the watch underwhelming and cheap-looking, like a toy, while others love its appearance in person and its clean, appealing design as a smartwatch alternative. The stock leather strap is described as decent but basic and potentially short for larger wrists, with one owner advising a third-party replacement for durability. One owner of a different variant noted the date font is too small to be useful.
