The Panerai Luminor Submersible comes with slight variation from the Panerai Luminor. The case design was inspired by the case of the Luminor in 1950s and has components of the Luminor and Radiomir in its designing. Some of the Luminor Submersible models are evocative of the vintage acrylic crystals displaying a unique dome shape crystal case style. The stainless steel used in the case protects it from corrosion and the metal guard protects the crown. The design of the Panerai Luminor Submersible is the perfect balance of tradition and innovation. The Panerai Luminor Submersible PAM01024 has an automatic movement with 3 days of power reserve.
