The Aquanaut Ref. 5066 debuted in 1998, Just one year after the launch of the original Aquanaut Ref. 5060. Along with the Ref. 5065, It is considered the second generation, Succeeding the 5060. With a case size of 35.6 mm, It boasts a more classic proportion than today's Aquanauts, Which typically measure over 40 mm. The transparent sapphire caseback reveals the self-winding 330 SC movement, Establishing it as a mid-size reference that combines vintage sensibility with modern elements. This model represents the generation before the Aquanaut line underwent a major update in 2007. It retains a distinct vintage appeal from the modern Aquanauts, And is today considered a true neo-vintage collector's piece.
Ref. 5066 was produced in stainless steel (5066A, 5066/1A) and rose gold (5066J) versions.
