 The Panerai watch model produced in 1936 for the first Submersible is back again. The initial timepiece marked the appearance of a wristwatch manufacture under the Panerai name. It was developed in September 1935 by the request of the Royal Italian Navy that required a luminous underwater diver's watch. The development of the watch became a turning point for Officine Panerai, which had continuously specialized in manufacturing of an impressive series of instruments with distinguished technical features: - mechanical calculators for torpedo-launches,
- self-luminous devices for night gunnery,
- underwater compasses,
- mechanical depth gauges.
All the instruments listed above were characterized by the highest quality and were developed to guarantee maximum reliability and accuracy during the missions performed by the Royal Italian Navy. The same constructional principles were used while developing Officine Panerai watches. After the prototype of the timepiece developed in March 1936, Officine Panerai introduced ten more examples that were subjected to strict tests to check their effectiveness of water-resistance and the supreme legibility of timekeeping under any conditions. The 1936 model passed all the necessary tests. It was equipped with many innovations, with the use of Radiomir being the most prominent one. Radiomir is a special luminous paint that contains zinc sulphide, radium bromide and mesothorium. The case of the watch featured a cushion-shape reflecting the fashion widespread in the 1930s. It was characterized by large size, measuring 47 mm in diameter. The black dial of the Radiomir 1936 revealed a combination of baton-shaped hour markers and Arabic and Roman numerals. The Panerai Radoimir 1936 introduced in 2007 inherited these unusual aesthetic details. The timepiece was developed in a limited series of 1936 steel units and 99 platinum. The dial of the Panerai watch is covered by the Plexiglas crystal, a material similar to the Perspex plastic initially used by Officine Panerai. The material offers perfect transparency along with utmost resistance to atmospheric agents and acids. Drop a glance at the dial of the Radiomir 1936 and you will feel the air of mystery of its legendary predecessor. The modern version bears no inscription, maintaining the anonymous nature of products being tested by the special services. The lack of inscription kept the manufacturer away from the risk of being identified by the enemy during wartime missions that could lead to actions of sabotage or spying. The new timepiece is equipped with the Panerai calibre OP X, a manually-wound movement operating at 21,600 vibrations per hour. The mechanism embellished with Cotes de Geneve decoration and blued screws provides 56-hour power reserve. Officine Panerai created Radiomir 1936 to sparkle nothing but positive and pleasant emotions. The price of owning this timekeeping pleasure is just 4,800 Euro for the steel version and 29,000 Euro for the platinum one. |
