Editor's Notes

Oris' is driven by the joy of mechanics and its '400' series celebrates the feat of engineering that is automatic mechanical watchmaking. That calibre is both literally and figuratively at the heart of this 'Aquis Date' model, built in-house with elevated levels of antimagnetism and a five-day power reserve. The case and bracelet are cast from stainless steel, while the green ceramic unidirectional bezel mirrors the sunburst dial.

We offer a two-year warranty for all working parts and manufacturing faults for luxury watches. For more information, contact one of our experts by emailing watches@mrporter.com
