Rolex Explorer II 1655
This is the first member to the family of Rolex Explorer II, and it came out as the larger sibling to the Explorer I. This reference featured a sporting dial of 39mm with stainless steel case and matching steel bracelet. These watches were created specifically for the spelunkers, thus with its added features, it was made practical for them. The first feature was the extra 24-hour hand that points to a fixed bezel with the 24-hour markings, and the reason behind this was that the spelunkers are usually in the dark and thus cannot depict and know the difference in the timing, that is whether it is AM or PM. The watch was equipped with an orange hand which was later replaced with the red one. The Explorer II runs on a 1570/1575 caliber which is as same as that of the GMT-Master. It is also heavy on the lume details which ensures optimal legibility in the dark.
