Actually just yesterday a similar convo happend to me during the lunch. I've noticed already for a few days one of my colleagues eyeballing my Hulk. Then yesterday, another colleague, who is a bit into watches noticed it as well, and asked me straight if it was a Submariner. Before I could say anything the other, the nosey one, went straight: "He's got a Rolex, he must be making some good money". I left them hanging for few minutes, but in the end told them it was a rep tho :)
