Oris's video: Oris BC3 Day Date Time to clean the air No 42

Ouch. When this BC3 Day Date pilot’s watch landed at our Hölstein HQ, it looked like it had crash landed. The brief: clean it up, get it flight-ready again. Possible? We like a challenge. Have a watch to see if we gave this one back its wings. /////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// ►PRODUCT INFORMATION Model: BC3 Day Date Ref.
