Bell & Ross creates functional watches for professional users. One of their inspirations is the instrumentation on board. They took a flight instrument from the dashboard to put it on the wrist and they launched their iconic collection called ‘Aviation’. Bell & Ross also draws its inspiration from the military watch history. For each period they have one collection and they respect all the design and color code of each of them. The collection of Bell & Ross watches is based around five collections each corresponding to five different periods in the history of aviation, with its technical and stylistic revolutions: PW1, WW1, Vintage, Marine and Aviation.
