What people say

Owners + reviewers, side by side

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

Oris Big Crown Calibre 113

The Oris Big Crown Calibre 113 is noted for its distinctive mint green and rose pink dial, a 43mm stainless steel case, and an in-house hand-wound movement offering a 10-day power reserve. It includes a business calendar complication, day, date, and a non-linear power reserve indicator, with excellent readability provided by Super-LumiNova. One reviewer found the bold dial color potentially clashes with a business context and wished for a smaller case size. The Oris Big Crown Calibre 113 is priced at CHF 6,350 / €6,350 and includes a five-year warranty. Overall, reviewers highlight the Oris Big Crown Calibre 113's unique dial and extensive complications as its primary draw.

Bremont ionBird

Owners report the Bremont ionBird is overpriced and features a printed dial with a poorly placed date window at 4:30, which some find visually disruptive. However, some owners suggest its case finishing is superior to competitors. The 43mm titanium Bremont ionBird GMT is powered by a COSC-certified BE-93-2AV automatic movement and retails for $5,795. On balance, owners and reviewers find the Bremont ionBird's date window placement and price point to be significant drawbacks.
