Design, protection and functionality
by Volker on Jun.12, 2014, under Allgemein
Doubtless one of the iconic Panerai design elements: the crown protection device. The patent was issued in july 1956 and described as “tight-seal device for the control knob of instruments, particularly for the setting and winding knob of watches”.
A 26 mm wide and 6.2 mm high area is milled out on the right edge of the polished case of Ref. 6152/1 watch, to allow a lateral attachment of the protection device, made from brushed stainless steel. The protection system, which is extending 8 mm above the right side of the case is fastened to the case with two screws. The L-shaped protective bar (in open position visible on the photo) is 2.9 mm wide and pushes the crown down firmly to the case when closed.
