The Day-Date in platinum can be considered the king among kings. When fitted with a smooth bezel such as the present watch, it is a discrete and private pleasure; the heft will remind its owner of the special metal in which it was crafted, while to many it will look just like a steel watch. The 18026 pictured here is fitted with a dial in Lapis Lazulli, further enhancing its desirability. It was manufactured in 1984 and part of a 2013 Christie's sale.
