百达翡丽，不锈钢自动上弦腕表，配中心秒针及日历显示，AQUANAUT，型号5167A-001，约2021年制 ，附原厂证书、盒子及外包装

Launched in 1997, the Aquanaut is a modern classic beloved by many for its versatility and distinctive design. Inspired by the Nautilus, the watch sported a “tropical” strap, made to be ultra-resistant to wear, salt water and UV radiation. In 2007 Patek Philippe launched the reference 5167 series, featuring a more subtle textured dial and a larger case.
