The Panerai Luminor 1950 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 1950 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 1950 is the perfect balance of tradition and innovation. The Panerai Luminor 1950 10 Days GMT PAM00441 has an automatic movement with 3 days of power reserve and a date window at 3 o'clock position.
