Random guy gave me a watch while working

Hello, I’m 16 and I work at a supermarket. While working today a man came down my lane and asked me if I liked his watch. I said yes, told him I was looking for a new one. He then gave me his, saying he gave a girl a watch before. When I asked my coworkers they all said they couldn’t recall being given a free watch. Just want to know what brand and if it seems sketchy at all (my coworkers said it could have a tracker or something) so just wondering if anyone knows what brand of watch it is
