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.

Phoibos Leviathan

Owners widely praise the Phoibos Leviathan for its excellent value, superb case finishing, and generous lume. The watch is described as visually striking, legible, and well-made, with a unique case design, sapphire crystal, and a comfortable FKM strap or excellent bracelet with a milled clasp and quick adjustments. Some owners note the bezel's staggered jimping can cause fingers to slip, and the beveled crystal can distort the view of indices. Accuracy varies, with one owner reporting losing 5-10 seconds per day without a winder, while others state it keeps accurate time out of the box. The watch is frequently described as heavy and thick, with some owners finding it too large for wrists smaller than 7.5 inches, although newer models feature an improved clasp for better comfort and functionality. Overall, owners rate the Phoibos Leviathan highly for its striking design and impressive finishing at an accessible price point.
