With two Officine Panerai Tokyo servicing invoices in Japanese with reception dates 25 March 2010 and 1 April 2008.
The present set is an extremely rare so-called "Trittico", a triple combination, made by Panerai for the Egyptian Navy. The watch, a very well preserved example of the celebrated "Egiziano" reference GPF 2/56, is an important witness of the development of professional divers' watches, reflected by its charismatically aged dial which turned from black to tones of warm hazelnut-brown. Such dials with nearly perfect patina are also referred to as "tropical" dials.
Both the compass and the depth gauge are distinguished by their very good, original overall conditions, the rarity enhanced by the presence of the original water-resistant leather straps and the large stainless steel buckles.
The "Egiziano" reference GPF 2/56 is described and illustrated in The Panerai in Florence by Dino Zei, p. 66, and in Vintage Panerai - The References by Ralf Ehlers & Volker Wiegmann, pp. 257 - 283.
Guido Panerai & Figlio
Guido Panerai & Figlio, founded in 1860 in Florence, advanced quickly to the official watchmaker of the Italian Navy and produced extremely modern and precise instruments. In 1936 the company, later renamed Officine Panerai, launched the first prototype of a diver's watch, the Radiomir. During World War II, watches and other instruments made by Panerai were standard-issue tools for Italian Navy frogmen, SLC torpedo riders and commandos, later also for naval forces of other countries such as Egypt.
The models were equipped with a crown protecting bridge, invented by Panerai in 1943 (patented in 1956). Its main functions are protecting the crown from shocks, compressing the sealing gasket with the lever to make the watch water-resistant to a depth of 200 metres and allowing the rewinding of the watch when submerged.
The instruments were fitted with brushed inox and stainless steel amagnetic cases, transparent plexiglas domes, black dials with luminous indications, leather straps and steel buckles. The compass features a luminous rubber band to the inside of the plexiglas dome.
The depth gauges were produced in various versions, corresponding to the maximum depth required.
