Panerai Radiomir 1940 Limited Edition (PAM00399) manual-wind watch, features a 47mm stainless steel case surrounding a black dial on a brown leather strap with a stainless steel tang buckle. Functions include hours, minutes, and small-seconds. The PAM 399 preserves the essential features of its sibling but adds nuance to set itself apart as the sportier of the two 1940s. A polished stainless steel Radiomir 1940 case recalls the base metal origins of the original Panerai combat dive watches, and a matte black dial provides the ideal backdrop to achieve a powerful two-tone impact. The PAM 399 preserves the rose gold hands and simulated aged-radium indexes of the of the 398, but the remainder of the 399's details hew closer to Panerai's mil spec past than its luxury present. A calf leather brown strap with contrasting stitch and simple ardillon buckle secure the timepiece on one's wrist.
