What people say

Owners + reviewers, side by side

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

Oris Aquis Date Calibre 400

The Oris Aquis Date Calibre 400 is widely lauded for its exclusive in-house movement, offering a five-day power reserve, 10-year warranty, and 10-year service interval. Reviewers and owners praise its impressive accuracy, with figures ranging from under a second per day to seven seconds fast per day. The watch features a refined case with slimmer lugs and an updated dial for improved ergonomics, a patented quick-change system for straps, and a smooth, precise bezel action. Some find the dial can be shiny with glare from the domed crystal. Overall, owners and reviewers rate the Oris Aquis Date Calibre 400 highly for its significant advancements in mechanical watchmaking and value proposition.

Fortis Marinemaster M-40

Owners praise the Fortis Amber Orange for its gorgeous appearance and strong wrist presence, noting its crazy lume and 70-hour power reserve. The Doxa SUB 300T, described as having a superb, eccentric design with a highly legible dial and functional no-decompression bezel, uses an ETA 2824-2 movement. However, the SUB 300T's 42.5mm case wears large and its 14mm thickness is not ideal for dress shirts, though it boasts 1,200m water resistance. On balance, owners appreciate the Fortis Amber Orange for its striking aesthetics and impressive lume.
