This is a 100% original Oris BC4 chrono watch and when you buy it, please feel free to verify its authenticity with any authorized Oris dealer. This watch has a black dial, a Chronograph, self winding automatic movement, see through skeletal back, saphire crystal, black DLC tone steel case and a black leather strap with a deployment buckle. The watch has a 45 mm case. Please keep in mind even though this watch looks great and runs great, it is pre owned. If you look really close, you will see some scuffs or dings. It comes with the original box and papers. This watch has a MSRP of $4,100 but because it is pre owned, I will sell it for only $1,250.  Thank you
