When Patek Philippe launched the Aquanaut family in 1997, the idea was to offer women a casual yet elegant watch that they could wear on an everyday basis. The hallmark traits of the Aquanaut family are clear, with its rounded octagonal case, embossed dial, and attractive chocolate bar pattern. The practical 35.6mm stainless steel case features a screwed-down crown and is water-resistant to 120 metres. This particular model, released in 2015, comes with a rich, chocolate brown-coloured dial and the bezel is set with 46 diamonds for an extra touch of femininity. For women who want the freedom of a watch they do not have to remember to wind, this Aquanaut model comes with a quartz movement and has luminescent indices and hands for enhanced legibility in the dark. Like all members of the Aquanaut family, the strap is made from a comfortable high-tech composite material, which replicates the texture on the dial.
