What people say

Owners + reviewers, side by side

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

Marathon OSAR-D (Original SAR with Date) Automatic 41mm

The Marathon OSAR-D (Original SAR with Date) Automatic 41mm is noted for its highly legible white dial with applied hour markers and a functional date magnifier, emphasizing its tool-watch purpose. Its Swiss-made Sellita SW200-1 movement is considered reliable and serviceable. One reviewer found the bracelet lacked refinement and preferred the rubber strap option. Overall, owners and reviewers appreciate the Marathon OSAR-D (Original SAR with Date) Automatic 41mm for its excellent legibility and robust movement.

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.
