HANDS Original


Known to be produced in 8 pieces only, the elusive reference 1831is the ultimate day-date produced in platinum on platinum bracelet in the massive heavy Oysterquartz case. According to our research it seems that these watches were ordered exclusively by the Shah of Iran to be gifted to dignitaries.
This story make further sense as the current owner confirmed that the watch was bought from a minister of Iran in 1983 and that the watch was originally delivered to Iran in 1977. The watch has since been kept in a safe in Switzerland unworn. This is the third known of the eight to surface to the market (No. 02 serial 5086929 and No. 04 serial 5086931) and interestingly bears the exact same dial characteristics as the No.02. Worn only on a few very rare occasions and probably never polished, it has been preserved in almost as new condition with all hallmarks and engravings crisp and deep. Weighing in at a massive perfect 300 gramms and a perfect stella dial, there is no doubt that this watch will hold a coveted place within any serious Rolex collector?s vault.
