Panerai Mare Nostrum

About this reference

The Panerai Mare Nostrum PAM00300 was released in 2010 as a limited edition of 99 units. This reference is a faithful recreation of the 1943 prototype deck chronograph designed for Italian Royal Navy officers. It features a 52mm brushed stainless steel case with a two-step bezel and a black multi-level dial. Unlike the 1990s Pre-Vendome versions that utilized ETA movements, the PAM00300 houses the hand-wound OP XXV caliber, which is built on a Minerva 13-22 base. This movement is visible through a sapphire crystal caseback, a departure from the solid backs of earlier military-style models. Collectors prioritize this reference for its historical accuracy in scale and its high-grade movement. On the secondary market, prices typically range between $25,000 and $35,000 depending on provenance. A notable variant is the PAM00603, which utilizes the same movement and dimensions but features a titanium case and brown dial.
