Paying tribute to the 20th anniversary of the Aquanaut launched in 1997, the men’s model is now available in the new 42.2-millimeter “Jumbo” format. It features an embossed dial subtly gradated from black to night blue. Decidedly masculine looks for this incarnation of casually elegant chic framed by a delicately satin-finished bezel. The white-gold case is water resistant to 120 m and protects the self-winding caliber 26‑330 S C movement.
