More about Audemars Piguet:

In 1972 Audemars Piguet launched the Royal Oak wristwatch, a steel luxury wristwatch with the vision that a non-precious metal watch would appeal to collectors based on the finely executed design and quality of movement. Initially criticized and difficult to sell, the Royal Oak went on to be one of the most successful and recognizable models for the brand. The development of an automatic ultra-thin perpetual calendar movement in 1978 allowed Audemars Piguet to bring together a tenet of the foundation of the company, designing and producing complex and precise calendar watches, and a watch model that was instantly recognizable.

The self-winding Royal Oak perpetual calendar wristwatch was introduced in 1983, eleven years after the launch of the original Royal Oak wristwatch. The dial displayed the 12 months of the year without any leap year indication, presenting a balanced dial design that perfectly complements the iconic octagonal bezel. The present watch is Number 10 of an exceedingly small series of Royal Oak Perpetual Calendar wristwatches cased in platinum and with a mother-of-pearl dial. No doubt Audemars Piguet chose to case this series in platinum due to its rarity amongst the precious metals, and for its elegance, versatility, and durability.  The subtle luster of mother-of-pearl adds depth and luminescence to the dial, with shades of blue, grey, and purple. Rarely used on complicated watches due to the shell being so brittle and prone to breakage, mother-of-pearl adds a refreshing level of luxury to a perpetual calendar wristwatch. Less than twelve examples with this case and dial combination were produced in total, making this highly attractive and charismatic watch one to be coveted.
