| Vendor | Oris |
Product Description
Oris and Disney’s The Muppets Kermit the Frog get together for a bit of fun and to create “Kermit Day” with a very special edition of the ProPilot X Calibre 400.
Kermit appears on ‘Kermit Day’ – the first of the month. Like the green dial, the idea of this gentle, humorous touch is to encourage us not to take life too seriously. To look up, smile and do something we enjoy, something fun. That might take five minutes. A moment of quiet reflection for some. For others, a cup of coffee, a phone call, a bath, a short walk. Find the joy.
The watch is fitted with Oris Calibre 400, the innovative in-house automatic Oris spent six years developing. The movement makes three key performance promises: anti magnetic, five day power reserve and a 10 year warranty.
