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.

Longines PrimaLuna Moonphase

The Longines PrimaLuna Moonphase features a fluid case design and a 72-hour power reserve from its automatic movement. Owners note its accuracy averages 1.3 seconds lost per day across six positions, and 3 to 4 seconds on the wrist, performing within COSC standards. Previously, moon phase models utilized quartz movements, a detail that may not appeal to mechanical watch enthusiasts. Overall, owners rate the Longines PrimaLuna Moonphase highly for its updated automatic movement and reliable timekeeping.
