What people say

Owners + reviewers, side by side

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

Sinn 717

The Sinn 717 is widely praised for its legible, cockpit-instrument-inspired dial and the functional SZ01 movement with central chronograph minute and second hands. Owners appreciate its solid winding action, crisp button feel, and accurate date changes. Despite its 45mm diameter, the Sinn 717 wears well due to its short lug-to-lug distance and comfortable strap options, and its TEGIMENT-treated black PVD case offers significant scratch resistance. Reviewers highlight its robust build quality and 200m water resistance, noting the innovative bezel sealing. Some community members criticize the blacked-out case aesthetic, and one owner finds the bezel action stiff, which they also see as a positive for preventing accidental turns. On balance, owners and reviewers rate the Sinn 717 highly for its unique legibility, robust construction, and comfortable wearability at its price point.

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.
