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.

Sugess Seestern S456 GMT

Owners widely praise the Sugess Seestern S456 GMT for its excellent case finishing, deep blue sunburst dial, and crisp indices, with one owner rating the overall fit and finish 9.5 out of 10. The watch is noted for its legibility, strong lume that lasts about 4 hours, and accurate timekeeping around -4 seconds per day, with easy GMT hand adjustment. Some owners report issues with a loose or friction-based unidirectional bezel, while others find theirs tight and prefer a bidirectional GMT bezel. The sapphire crystal is described as clear and flat by some, but others find it very reflective with AR coating that could be improved. Sizing is generally considered good at 39mm with a 46mm lug-to-lug and 12mm thickness, though one owner expresses concern about its 49mm lug-to-lug and 41mm bezel diameter. Overall, owners rate the Sugess Seestern S456 GMT highly for its impressive finishing and dial at its price point.
