The Royal Oak Offshore Rubens Barrichello II leans into the line's motorsport side, with a 44 mm titanium case and black dial that keep the look direct and technical. Here, that angular Offshore case is paired with an alligator strap, which gives the watch a dressier edge. The automatic movement powers a chronograph and date. At 15.6 mm thick, it has the broad, planted feel collectors expect from the Offshore.
