5164A-001 Aquanaut 40.8mm Black Polymer Tropical Strap Black Embossed Dial Steel Bezel

When it was first introduced in 1997, the Aquanaut caused quite a stir with its youthful, contemporary, and unexpected design. Its rounded octagonal case was influenced by the Nautilus, and it featured a “tropical” strap made from a cutting-edge composite material that was highly resistant to wear, salt water, and UV radiation.
