Pre-owned Panerai Submersible QuarantaQuattro ref PAM01596 (2025). The Submersible is Panerai’s modern professional dive watch, and the name “QuarantaQuattro” simply means 44 in Italian, referencing the watch’s 44mm case size. The design follows the familiar Panerai formula with a rotating dive bezel, large luminous markers, and the brand’s signature crown guard protecting the winding crown. The dial features skeletonized hands filled with lume, along with a small seconds display and a date window for everyday practicality. Meant for underwater use, the watch carries a 300-meter depth rating, making it a true dive instrument rather than just a sport-styled watch. The watch is powered by Panerai’s automatic caliber P.900 movement, which has a convenient three-day power reserve. Paired with a rubber strap, the Submersible QuarantaQuattro delivers the rugged functionality Panerai fans expect. Shop Panerai Submersible Collection
