“kept together by six screws” – the giant GPF 2/56

by on Jan.08, 2017, under Allgemein

gpf256_construction_2_600x600In many respects, the GPF 2/56 set new standards in terms of design at Guido Panerai & Figlio: The casing diameter, now at a stately 60 mm (or 66 mm including the crown-protecting device), made the earlier Panerai watches with their 47 mm casings look small by comparison. This was also the first time a rotating bezel with five-minute increments was used, a luminous reference point at 12 o’clock and three other major indices at 15, 30 and 45 minutes. The inside of the rotating bezel is fixed securely to the casing and caseback with six screws at a distance of 60° on the underside. If the six screws are loosened, it is possible to lift off the caseback, the rotating bezel and the Plexiglas crystal from the watch casing. Unlike earlier Panerai watches, the caseback of the giant GPF 2/56 does not feature a thread but is fixed securely to the casing by the six screws. Compared to the Panerai watches used during the Second World War (bezel and caseback „twisted“ together by their internal thread onto the holding ring of the movement) as well as the watches produced in the 1950’s (bezel pressed onto the casing and caseback with external thread screwed onto the centre of the 47 mm casing).

While the crown-protecting device was a very prominent, almost “superimposed” addition to the Reference 6152/1, and could only be integrated into the Rolex casing to a certain degree as a result of its construction, the GPF 2/56 clearly shows the “completely seamless integration” of the legendary crown-protecting device.

The coffee table shot on the left shows page 1092 – 1093 in chapter IX.I of our book “The References” 1950’s-1960’s with a photo of the screwed caseback of a GPF 2/56 (left) and an illustration of the construction of the “kept together by six screws” GPF 2/56 (right). Enjoy reading!

A patent and its realization in shape of the GPF 2/56

by on Jun.23, 2016, under Allgemein

IMG_3394_600x600One of the unique technical features of the GPF 2/56 compared to other watches from Guido Panerai & Figlio is the rubber sealing ring of the winding crown.

The famous patent 545668 from November 1955 can be seen right next to its realization on page 1148-1149 in chapter IX.II, showing the side of a GPF 2/56 “Luminor Panerai” with removed crown-protecting device and crown with its rubber sealing ring, making this area of the watch watertight when the lever is closed by axial pressure to the case.

Vintage Panerai watches with the legendary crown-protecting device are featured in the second volume of our book “The References” 1950’s-1960’s in chapters VIII (Ref. 6152/1 with Rolex movements), IX (GPF 2/56) and X.IV (Modified Reference 6152/1 with Angelus movements).

We would like to express our sincere words of thanks to Officine Panerai for making the famous patent 545668 available for the effective comparing view on the double page in our book, shown above. [Ralf Ehlers & Volker Wiegmann]

Missions of the Egypt frogmen

by on Jun.15, 2016, under Allgemein

IMG_3433_600x600The Red Sea, the Straits of Tiran, the Gulf of Aqaba, even the shores of Dakar (Senegal) and Abidjan (Ivory Coast) – target zones of the Egypt frogmen during the Suez Crisis, the Six-Day War and the Yom Kippur War.

Not very much has been ever published before about missions against enemy ports, ships and oil platforms during the conflicts between Egypt and Israel. In the mid-50’s, both Egyptian and Israeli special forces attended separate training courses in Italy to learn the skills for underwater missions from their Italian instructors. After our search for historical documents and with the support of a high decorated Egypt frogmen veteran we were able to put a spotlight on some of the missions carried out decades ago.

Read the historical background on watches and instruments from Guido Panerai & Figlio used by the Egypt frogmen in chapter VII and IX of “The References” 1950’s-1960’s (second volume), accompanied with rare historic photos (page 794-795 shown in the coffee table shot above). The new “The References” books (two volumes with 696 pages each) can be ordered only in our bookstore. Enjoy reading!

The sixty years old “Panerai app”

by on May.15, 2016, under Allgemein

IMG_3049_600x600Guido Panerai & Figlio’s legendary, patented crown-protecting device from the 1950’s – today it would be called a “Panerai app for underwater wristwatches”. How to describe this functional feature from the past today? Lets give it a try:

System requirements: Ref. 6152/1 or GPF 2/56 case. Protecting the winding crown during underwater use. Release lever for winding the movement and setting time.

Approved decades ago, the crown-protecting device turned into a legend many years later. This “Panerai app” created an unique look which attracts watch collectors around the world. Available on modern Panerai watches, made for the public since 1993, the crown-protecting device carries the Panerai DNA from the past into the future.

Vintage Panerai watches with crown-protecting device are featured in the second volume of our book “The References” (1950’s-1960’s) in chapters VIII, IX and X.

Unique feature: The “8 Giorni Brevettato” symbol.

by on Mar.15, 2016, under Allgemein

IMG_2358_600x600The GPF 2/56 features several unique features among all models produced by Guido Panerai & Figlio. The huge case with the rotating bezel was entirely produced by the company from Firenze, using Angelus movements to reach a power reserve of eight days. This was expressed by the use of the unique “8 Giorni Brevettato” symbol, engraved at 3 o’clock on the “Radiomir Panerai” and “Luminor Panerai” dials (both of these dial versions were used in watches of this reference).

The number of GPF 2/56 watches registered in our database has more than tripled since 2009 when we published “The References” for the first time. Read in chapter IX about the different versions of this reference (page 1058-1161). Chapter IX is dedicated to the GPF 2/56, in which five of these rare watches are featured. Aside the technical information of these legendary watches we have added historic information. The military background includes rare historic photos and four mission reports provided directly to us by an Egypt frogmen veteran (page 1064-1071).

The coffee table shot shows page 1155-1156 of chapter IX.II, a GPF 2/56 with grey coated case and “Luminor Panerai” dial. Information on “The References” 1950’s-1960’s (second volume) can be found here.

Our new “The References” books can be ordered only in our bookstore.

GPF 2/56 “Big Egiziano” @ Christie’s

by on May.20, 2015, under Watch Point

Christie’s New York will have a rare GPF 2/56 “Radiomir Panerai” with Angelus movement (LOT 154), made for the Egyptian Navy, in their upcoming Important Watches auction 3752 (June 17th).

This “Egiziano Grosso” bears the matriculation number 012 on the inside of the caseback, which is screwed onto the body by six screws. The “engine” of this watch with a case size of 60 mm and rotating bezel, the Angelus Cal. SF 240 eight-days-movement, is signed “12.55” and equipped with an Incabloc shock protection.

The Angelus movement can be clearly identified on the face of the huge watch by its small second function with a subdial at 9 o’clock. Hour and minute hand are shaped in the “single pencil” style, which is also typical for Vintage Panerai watches with Angelus movement. The sandwich dial bears the “8 GIORNI BREVETTATO” symbol on the right side at 3 o’clock. This engraved symbol is an unique feature in the range of Vintage Panerai watches, and can be found only in this particular reference, which was produced for the Egyptian Navy.

Features of the watch:
Reference: GPF 2/56
Dial: “Radiomir Panerai” (sandwich, engraved)
Case number: 012
Movement: Angelus Cal. 240 SF (8 days)

This GPF 2/56 “Radiomir Panerai” is already recorded in our database and has been published in our book “The References” (first edition 2009 / chapter V).

We hope the watch will find a good new home and that it remain surfaced in the Vintage Panerai collectors world. [Ralf Ehlers & Volker Wiegmann]

“Chronos” on Panerai: “Keeper of the Grail”

by on Oct.11, 2014, under Allgemein

German editor Jens Koch wrote an excellent story about the unique design of Panerai watches, following their roots from the past until today and in the future. The actual special issue of “Chronos” watch magazine (“Uhrendesign” / “watch design”) features his story on page 92-100.

By describing the history of Panerai from the early beginnings as a supplier of the royal italian navy until today’s models, photos of Vintage Panerai watches are featured (Ref. 3646 / Type D “Kampfschwimmer”, Ref. 6152/1 “Luminor Panerai” and a GPF 2/56 “Egiziano Grosso”). Koch explains in detail where Panerai today still use the DNA of the historic watches and how the brand can create new models by using the classic design elements today and in the future, as well as different case sizes and new materials.

Get your copy of the “Chronos Spezial Uhrendesign” at the newspaper stores across europe. Find more info at www.watchtime.net [Ralf Ehlers & Volker Wiegmann]

GPF 2/56 “Big Egiziano” on auction @ Christies

by on Oct.16, 2011, under Watch Point

An interesting “Trittico” (= wristwatch, compass and depth gauge) is up for auction at Christies in their november sale 1383 (LOT 27). 

A rare GPF 2/56 “Big Egiziano” with “Radiomir Panerai” dial, a compass and a depth gauge will hopefully find a good new home on november 14th in Geneva/Switzerland.

Features of the watch:
Reference: GPF 2/56
Dial: “Radiomir Panerai” (sandwich, engraved)
Case number: 018
Movement: Angelus Cal. 240 SF (8 days)

The watch is a close “brother” of the “Big Egiziano” with the case number 012, published in our book “Vintage Panerai – The References” and shows identical features, especially the signed date “12.55” on the movement plate. The balance cock bears the “SF 240” sign (Stolz Frères Cal. 240), which can be found on the earlier versions of the Angelus movement (1955 – signed “12.55”), while the movements dated in the 1960’s (e.g. “MAI.61” or “JUIN.61”) have a “+/-” on the balance cock in the majority, from what we were able to find out by comparing with our database.

All three items of the “Trittico” are signed “OFFICINE PANERAI FIRENZE” on their casebacks. Each item has the complete number of original screws (6 each). All of them appear with their original leather strap and buckle.

The depth gauge is aimed 60 meters and bears the “Radiomir Panerai” sign on the lower part of the dial. All items show signs of use, the dial of the GPF 2/56 has faded into brown “tropic” color.

You can read more about the Ref. GPF 2/56 in our book “Vintage Panerai – The References”, chapter V, pages 256-283.
