Oris Big Crown Calibre 113vsFortis Flieger F-39

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.

Owners and reviewers widely praise the Fortis Flieger F-39 for its robust build quality, excellent finishing often compared favorably to more expensive watches, and legible utilitarian dial with distinctive color accents. The watch is noted for its precise bidirectional bezel action, excellent lume, and comfortable wearability, with one owner reporting accuracy of 1 second fast per day. Some reviewers flag the 39mm case as wearing large due to its lug-to-lug distance, and the 38-hour power reserve of the Sellita SW 200-1 based UW-30 movement is cited as a limitation, though newer versions feature a 70-hour power reserve. Overall, owners and reviewers highly regard the Fortis Flieger F-39 for its tool watch aesthetic and impressive machining and build quality at its price point.
