What people say

Owners + reviewers, side by side

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

Oris Divers Sixty‑Five Calibre 400

Owners and reviewers widely praise the Oris Divers Sixty-Five Calibre 400 for its refined finishing, comfortable bracelet, and the impressive Calibre 400 movement with its 5-day power reserve and 10-year warranty. The domed sapphire crystal and vintage-inspired design, including the tapered bracelet with rivets, are frequently highlighted. Accuracy is reported between +1.6 seconds per day and exceeding the 120-hour power reserve. However, some owners find the $3900 price point high, with one reporting a date wheel failure within a month and significant daily timekeeping issues after repair. The 10atm water resistance rating is also noted as a potential drawback by some. Overall, owners and reviewers rate the Oris Divers Sixty-Five Calibre 400 highly for its upgraded movement and compelling value.

From video reviewers

The 5-day power reserve of the Calibre 400 movement is a key strength. Reviewers did not reach a consensus on any weaknesses.

Bremont Terra Nova 40.5

The Bremont Terra Nova 40.5 Date Bronze is highlighted for its CuAl7Si2 bronze alloy case, which provides a warm, luxurious appearance and develops a gradual patina. It includes a gradient green dial with prominent Super-LumiNova numerals and a 40.5mm diameter. The watch is powered by the caliber BE-36AE, offering a 38-hour power reserve and 100m water resistance. The Bremont Terra Nova 38, a time-only field watch, features a 904L stainless steel case and vintage-inspired beige Super-LumiNova. Reviewers noted a preference for a screw-down crown and caseback for a field watch. On balance, reviewers praise the Bremont Terra Nova 40.5 Date Bronze for its distinctive bronze case and attractive dial, while noting the Terra Nova 38's utilitarian design and a preference for more robust water-resistance features on a field watch.
