I first noticed the Rolex Explorer II on the wrist of Bernardo Rojo, Creative Director at Joseph Abboud. He was wearing ref 16550 which features a red 24 hour hand.  Rolex has since updated this model with the controversial ref 216570, aka the 40th Anniversary Steve McQueen edition. If you work on set or have a camera in your hands I’d recommend spending your rent money on this.  Comes in white or black dial.
