I crashed a Duke 250 and someone stole my watch

I was careless with the bike. It is my cousin's bike. (I was not focusing on the road) Lost control crashed and I went over the median onto the other side. As soon I could I jumped off the road. Someone guided me over to the side. My phone was thrown off and that guy found it. I didn't think about my watch then. Another guy who came after started taking videos and photos instead of helping. I saw him walking around looking for something. I didn't realise that I had lost the watch yet. Someone took it. It had fallen off my wrist. And it's nowhere to be found. Not even the strap. The others confirmed that the video guy had been waiting around after we went to the hospital.
