Those interested in the history of watchmaking are well aware that the names Radiomir and Luminor, which today identify the cases, originally referred to the two luminous materials created to achieve the legendary visibility at night or underwater which have always been a feature of the dials of Panerai Radiomir 1940 replica watches. It began with the invention of Radiomir: this was a powder based on radium, patented by Guido Panerai in 1916, to make luminous gun sights and other optical devices exceptionably visible in the dark.
The Radiomir 1940 Acciaio Replica - the transition model between the traditional cushion case of the first Radiomir into the imposing Luminor 1950 case - will be the main focus of the new Panerai collection presented at the Watches & Wonders 2015. It was Radiomir which was used on the dial of the first- ever Panerai watch in 1936, and for several years this remarkable luminous substance was one of the closely- guarded military secrets which enabled the commandos of the Royal Italian Navy to carry out their extraordinary missions in the depths of the sea at night, equipped with instruments specially created by the Florentine watchmaker.
The replica Radiomir 1940 3 Days 42mm Acciaio PAM00574 is characterised by two main novelties: the calibre P.1000, a new hand-wound movement with a power reserve of three days entirely made in the Panerai manufacture in Neuchatel, and the light green Super-LumiNova used in the dial for markers and hands. The watch includes a system for preventing the total amount which works with the device for homing the seconds hands: once the winding crown is drawn out, the total amount wheel stops and also the seconds hands at 9 o’clock jumps to zero, making super easy to synchronise it using the reference time signal. The situation is 42 mm across and it is water-resistant against 10 bar within the polished AISI 316L stainless version and also to 5 bar within the gold version.
The distinctive, original component of these two new models may be the brown dial, its colour inspired with that from the vintage watches that have gone through the discolouring effect triggered through the luminous material. The substance used right now to achieve exceptional evening visibility, usual for all Panerai watches, is Grade An Excellent-LumiNova, put on the incisions produced in the dial akin to the classic, large markers which indicate the hrs. To safeguard the dial, the very is created not of azure glass but of gently cambered Plexiglas, as with the vintage good examples in which the very is made of polymethylacrylate. Both your hands too reproduce individuals from the period Panerai watches and also the OP reference is engraved between your lugs, just as it had been within the historic models.
