Just because… the crown protecting device

by on Mar.18, 2012, under General

Rainy spring day here in Germany today, so I tried to catch the Panerai DNA in shape of the crown protecting device on the Ref. 6152/1 “Luminor Panerai”. It is without a doubt “the number 1 identifying feature” of Panerai watches from all production periods: vintage, PreVendome and actual models.

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, to allow a lateral attachment of the protection device, which is fabricated 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 is 2.9 mm wide and pushes the crown down firmly to the case when closed. 

You can find more information about Ref. 6152/1 watches in our 2nd book “Vintage Panerai – The References” in chapter IV, pages 202-255. About the crown protecting device you can find information on pages 225 to 233.
