Dan Bilzerian claims someone jacked his luxury timepiece right off his wrist during the Canelo Alvarez boxing match in Las Vegas ... and now the cops are involved.
The playboy poker player tells TMZ ... he was wearing a Richard Mille watch, valued between $950k and $1 million, to the Canelo fight and at some point, he noticed it went missing from his wrist.
Dan says he was taking a bunch of photos with fans as he walked toward the ring, and thinks someone may have slipped it off his wrist in the scrum because the carbon fiber watch is very lightweight and doesn't have a lock on the clasp.
