Oris and Disney’s The Muppets Kermit the Frog collaborate to commemorate “Kermit Day '' with a very special edition of the ProPilot X Calibre 400. The ProPilot X Kermit Edition has a green dial, naturally, but its most entertaining feature appears on the first of every month, or ‘Kermit Day’, when Kermit’s cheery face pops into the date window.The first function of every Oris watch, in the purest emotional, feel-it-in-your bones sense, is to bring joy, to make people smile. For some time, Oris have been trying to find the ultimate expression of this and to make a watch that’s pure joy. Inside the ProPilot X Kermit Edition is one Oris’ new generation of high-performance automatics. Conceived entirely in-house by their skilled engineers, Calibre 400 Series movements all feature elevated levels of anti-magnetism, a five-day power reserve and a 10-year warranty.
