In 1956, Panerai filed the patent for its crown protection bridge, which went on to become the distinctive feature of its 'Luminor' model. Detailed with the innovative latch, this 44mm '1950' version has a high-tech ceramic case created using a complex series of techniques, which make it five times harder than stainless steel. It's powered by the P.9010 calibre movement and has a date function, second sub-dial and three-day power reserve achieved by two barrels and an oscillating rotor that winds the springs in both directions.
