Characterized by its blue and black bezel, the GMT-Master II Batman is one of Rolex's most popular modern sports models. Rolex introduced the first GMT-Master II Batman in 2013 and has since replaced that original reference with a newer model with a handful of design updates and a new-generation movement.
