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.

Yema Superman Slim CMM.20

Owners and reviewers praise the Yema Superman Slim CMM.20 for its appealing retro design, balanced 39mm case, and in-house CMM.20 micro-rotor movement, with some finding the fish scale bracelet attractive. Concerns exist regarding its $2500/€2,490 MSRP, with some owners questioning its value and noting the potential for QC issues or a "jittery" seconds hand attributed to the new movement. The bracelet's articulation and stamped clasp draw criticism, though some owners report it improves with wear. Overall, owners and reviewers appreciate the Yema Superman Slim CMM.20's vintage styling and unique micro-rotor movement, but its value proposition and some finishing details are points of contention.
