While the Royal Oak or may be Audemars Piguet's most famous and iconic model, the manufacture also excels in gem-set jewelry watches, as exemplified by this opulent, diamond encrusted watch. While this timepiece does not have any additional complications beyond telling the time, it is a study in savoir faire and also proof of Audemars Piguet's breadth as a brand in terms of product offering and design.

The present watch features brilliant-cut diamonds on the bracelet, clasp and bezel. The bezel is further enhanced by a ring of baguette-cut diamonds that forms a cushion shape, and the dial is completely set with pavé diamonds and sapphire-set numerals. Of note is the quality of the gem setting on the timepiece - the bracelet is flexible, soft and smooth - all tell-tale signs of craftsmanship and know-how when setting the diamonds.

Presented in excellent overall condition, the watch is particularly unique because the case back is inscribed with "No. 1", suggesting that the present watch was the very first example to ever appear on the market. One can only surmise that it was a special order or a highly limited piece, made for a special client with exacting taste and standards.
