1993 "Pre-Vendôme Era" Legendary Reissue This long-awaited model faithfully recreates the historic "Ref. 5218-202/a," a legendary timepiece produced in extremely limited quantities for members of the Italian Navy before Panerai joined the Richemont Group.Carefully Crafted "Non-Matching" Aging Effect: The accidental discoloration seen on original pieces—where the indices and hands have aged over time (caramel-colored luminescence and green hands)—has been intentionally recreated using safe, modern Super-LumiNova to evoke a vintage feel. Single-Layer (Monolayer) Hollow Dial: Instead of the two-layer sandwich dials commonly used today, this model features a single-layer monolayer dial faithful to the original.Luminescent paint is applied to the grooves of the numerals and indices to create a three-dimensional shadow effect. Sturdy Matte Black DLC Case The 44mm stainless steel case features a scratch-resistant "DLC (Diamond-Like Carbon) coating" instead of the PVD finish used in the original, creating a rugged texture.Equipped with the in-house hand-wound Cal. P.6000 It is equipped with the highly reliable in-house hand-wound caliber "P.6000," which boasts a long power reserve of approximately 72 hours (3 days).
