The Patek Philippe Aquanaut ref. 5060, initially released in 1997 was the first wristwatch from the brand to be fitted with a rubber strap. The well-received model was first released as a limited edition of 1,000 pieces to commemorate the renowned Nautilus' 20th anniversary. The timepiece directly takes its inspiration from the Nautilus. Later examples were fitted with sapphire casebacks proudly showcasing the durable self-winding caliber with straight line lever escapement and a solid gold rotor, which was the same as early instances of the reference from the late 1990s.

Rare and sought-after, the present Patek Philippe ref. 5066 with a blue dial was released after the original version in very small quantities exclusively for the Japanese market. As observed from the service seal the watch is offered in excellent overall condition of both case and dial. Given the small amount of production of "Japan Edition" that are known to exist on the open market, it's safe to say that this is a rare opportunity to add one of the most unusual and charismatic Aquanaut models in one's collection.

Offered with its complete set of accessories including a blank Certificate of Origin, Patek Philippe Japan service guarantee and its original presentation box, the present ref. 5066A-010 is a great opportunity for collectors to acquire one of the rarest variants of the model in stainless steel. To our knowledge and through research, the present lot is previously unknown example and is the 12th example of the reference to appear at auction.
