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 S434 Pro Diver

Owners widely praise the Sugess Seestern S434 Pro Diver for its impressive finishing and craftsmanship at its price point, highlighting the applied indices that play with light, excellent BGW9 lume, and attractive color options. Specific positive notes include the domed sapphire crystal, short lug-to-lug, and on-the-fly clasp adjustment. However, some owners report quality control issues such as misaligned bezels or indices, while others with V2 models experience no such problems. Caveats include slight bezel back play, light AR coating on the crystal, and a clasp that could be smoother, with one owner desiring a color-matched date wheel. On balance, owners rate the Sugess Seestern S434 Pro Diver highly for its exceptional value and build quality, particularly the dial finishing and lume.
