The PAM359 represents Panerai's Luminor Marina 1950 3 Days Automatic in a 44mm polished steel configuration. This reference sits within the Luminor Marina series, distinguished by its automatic movement and three-day power reserve capability. The watch features a 44mm polished steel case paired with a matching polished steel bezel. Protection comes from a 2.6mm sapphire crystal, while water resistance extends to 300 meters. The piece is powered by the Calibre P.9000 movement, providing the stated three-day power reserve through automatic winding.

The polished steel construction and 44mm sizing position this reference for those preferring larger case proportions within the Luminor Marina collection. The automatic movement eliminates manual winding requirements while maintaining the three-day reserve specification.
