STEELDIVE SD1956S "Bronze Lumiinor" Automatic 500m Diver Watch

STEELDIVE SD1956S "Bronze Lumiinor" Automatic 500m Diver Watch

The Bronze SD1956S is inspired by the Panerai Luminor which is a watch with a very interesting history. Panerai had been making watches since 1860 and in 1935 they were approached by the Italian Navy to supply a watch resistant to extreme conditions, while at the same time keeping exact time for the frogman commandos of the First Submarine Group Command and offering excellent readability even under water. The prototype submitted by Panerai in 1936 was called Radiomir, from the name of the luminescent substance used for hands and indices, and passed all tests successfully. In 1938,Panerai was awarded the contract to supply the Navy. In 1949 Panerai introduced a new self-luminous substance called Luminor which was not only safer than radium-based Radiomir but also more luminous.The new tritium based compound was patented on 11 January 1949 under the "Luminor" trademark. The evolution from Radiomir to Luminor was completed in the Fifties with the invention of the signature crown-protecting device which was patented in Italy in 1955 and almost one year later in the USA. The patent application for a "Tight Seal Device" was filed by brother and sister Giuseppe and Maria Giuseppe Panerai, also listed as the inventors. Panerai continued their connection to the military and until 1993, their watches were only available to military forces.However, in that year, for the first time, the brand presented the Luminor and its variation Luminor Marina to the public. Directly inspired to a model of the past, the Luminor model quickly achieved an exceptional worldwide success.
