The Panerai Radiomir 1940 Marina Militare 3 Days (PAM00587) is a highly sought-after Special Edition released in 2014, limited to only 1,000 numbered pieces. It is celebrated by collectors for its historical accuracy, serving as a "transitional" homage to mid-century models that bridged the gap between the wire-lug Radiomir and the robust Luminor.
