Hands-on review ORIS Aquis 41.5mm with the new Calibre 400 movement. The Aquis is the watch community's favourite affordable luxury dive watch, and Oris took it to the next level by adding their in-house developed movement, cal. 400. This new movement was launched in 2020 and is anti-magnetic, has 5-days of power reserve, a 10-year warranty and service interval. Impressive for a £2,700 watch.
