Oris Divers Sixty‑Five Calibre 400vsVario 1918 Trench Brass

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.

Owners widely praise the Vario 1918 Trench Brass for its attractive, precisely made dial and case, with the evolving brass patina noted as a positive feature. The bund strap is considered comfortable and well-fitting by some, though others find it stiff and short for larger wrists. The lume is considered poor. The Miyota 82s5 movement is described as adequate, with accuracy ranging from about -10 seconds per day to simply running slow. On balance, owners rate the Vario 1918 Trench Brass highly for its fantastic looks and the unique character of its brass case.
