Setup, Compatibility & Care
Setting up the Oris Big Crown World of Aviation Watch is straightforward. To start, wind the watch by turning the crown clockwise about 20-30 times. Set the time and date using the crown. For care, avoid exposing the watch to extreme temperatures or magnetic fields. Clean the case and crystal with a soft, damp cloth. The leather strap can be cleaned gently with a leather-specific cleaner. Regular servicing every few years by an authorized Oris service center is recommended to maintain optimal performance.
