ROLEX EXPLORER REF. 6610
ROLEX EXPLORER REF. 6610 The Explorer was introduced to the market in 1953 to commemorate Sir Edmund Hillary and Tenzing Norgay's ascent of Mount Everest. Like many other Rolex models such as the GMT Master and the Submariner, the Explorer was designed for a specific purpose. In this case, it needed to be a compact-sized watch with high readability and a reliable movement that would function at any altitude. The case measured 36mm and the dial featured 3-6-9 markers for a perfect visibility. The reference 6610 was unveiled in 1955. It featured an upgraded movement, the caliber 1030, enabling a thinner case back. This update bestowed a sleeker and more modern look upon the Explorer, setting it apart from earlier models utilizing the thicker caliber A296, which necessitated a rounded "bubble back" caseback. Reference 6610 was produced for a very short period of time and was later replaced by reference 1016.
