The history of this Rolex Explorer II
Conceived in 1971 for cavers and polar explorers, the collection fulfils a very specific need: that of distinguishing between day and night during prolonged dives in total darkness. The large additional hand, which completes one revolution of the dial in 24 hours on a fixed bezel, was not originally intended as a second time zone indicator, but as a day/night marker. The 16570 model continues this historical lineage by introducing technical innovations whilst retaining the manufacture’s utilitarian ethos.
Case, movement and bracelet of this Explorer II
The 40 mm stainless steel case features perforated lugs typical of watches from that era. It frames a white lacquered dial known as ‘Polar’. This dial features ringed hour markers and hands with a distinctive profile. The original tritium luminescent material has developed a uniform, ochre-yellow natural patina, nicknamed ‘Chicchi di Mais’ by enthusiasts. The whole is protected by a flat sapphire crystal fitted with a Cyclops lens for reading the date. This timepiece is powered by the Calibre 3185 self-winding mechanical movement. It beats at a frequency of 4 Hz and offers a power reserve of approximately 50 hours thanks to its 31 jewels. Water resistance is guaranteed to 100 metres. The Oyster bracelet, reference 78360, in brushed stainless steel, with its 558B end pieces and single-fold clasp, secures the watch to the wrist.
Why this Rolex watch
The appeal of this configuration lies in its natural aesthetic evolution. The ‘Chicchi di Mais’ patina provides a distinctive visual contrast to the original white dial. Each watch ages differently, making this piece unique. The tritium-lit models from the 1990s are sought after for this ageing effect, which cannot be found on modern productions. As this model is no longer in production, it offers a compelling alternative to contemporary offerings. Owning this version provides the experience of an authentic patina combined with the robustness of a precision timepiece.
Contents and condition
Produced in 1996, this watch comes with its box, outer box, instruction booklets and the calendar from that period. The original warranty card is missing. The watch is in good condition. The case and brushed bezel show slight micro-scratches inherent to regular but careful wear. The strap shows natural, gradual softening.
