The Explorer II differs from the Explorer I in multiple ways. One major feature is the Explorer II is equipped with an additional 24-hour hand. The Explorer II does stay true to Rolex’s spirit of discovery and pioneering. In 1984, Rolex released a Red Hand Explorer II (reference 16550) that had a new face, bezel, movement and 24-hour hand. In 1988, the reference number 16570 was released with a new calibre. Everest bands and accessories are specifically designed for these “Red 24-hour hand” models that were released prior to 2011.
