Oris Aquis Date Calibre 400vsSpinnaker Spence 300

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.

The Spinnaker Spence 300 is widely praised for its slim 10.9mm case and 40mm diameter, offering a comfortable and uncommon thin diver design at its price point. Reviewers and owners highlight its value, especially below $350, and its blend of retro design with modern specifications, including a 300m depth rating and a fully indexed bezel. Some owners, however, find the dial printing and bracelet finishing to be less refined, with one noting the bracelet's male end links as a drawback. The consensus is that the Spinnaker Spence 300 is highly regarded for its exceptional value and wearable dimensions, making it a strong contender for an everyday sports watch.
