Patek Philipe launched the Aquanaut range in 1997 as a lower-priced alternative to the existing Nautilus range. A true sports watch, the Aquanaut features a rugged three-part case and screw-down crown for 120 meter water resistance, the most of any watch with a sapphire caseback at that time.
The original Ref. 5060 was released in 1997 a limited edition of 1,000 pieces. It featured a 36 mm case with a solid caseback. Inside was Patek Philippe's Cal. 330 S C central rotor automatic movement.
The Aquanaut proved very successful, so Patek Philippe put the Aquanaut into full production. Two sizes were available The 36 mm Ref. 5066 and the "Jumbo" Ref. 5065, with a 38 mm case. Ref. 5066 differed from the Limited Edition in that it had a sapphire display caseback.
