Certainly the most famous duo is made up of Paul Newman and the Rolex Cosmograph Daytona. It all began in 1969 when the film Winning, a film dedicated to the world of motor racing, is also proposed in Italy under the title Indianapolis, hellish track.

Le specifiche locandine pubblicitarie per il mercato italiano mostrano il famoso attore con al polso un cronografo Rolex ref. 6239 con quadrante exotic, che da lì a poco verrà conseguentemente ribattezzato “Paul Newman” dagli appassionati.  Il Rolex Daytona della foto, ref. 6241 del 1968, rappresenta un’innovazione doppia per la casa pentastellata.

Con questo orologio si riscontrano duplici funzionalità: lunetta con scala tachimetrica per la misurazione della velocità su un chilometro e pista circolare nell’estremita’ del quadrante, con un colore differente a quest’ultimo, per la visualizzazione del tempo. Questi particolari lo rendono estremamente utile in quegli anni, dove gli strumenti erano ancora non troppo evoluti e così viene utilizzato da molte persone.  Il meccanismo che viene utilizzato dalla casa pentastellata, è Valjoux 722-1, un movimento “calibro ” affidabile, tra i migliori che il mercato proponeva, che viene modificato da Rolex per renderlo consono ai propri canoni.    Questo splendido orologio, sta’ regalando ormai da tanti anni, un crescita del proprio valore, una rivalutazione stabile.
Alleghiamo un grafico che mostra il valore di un orologio standard ref. 6241 in acciaio, tornando indietro nella storia fino a i giorni nostri.

Rolex GMT Master “I Gilt dial”

Verso la metà degli anni ’50 i vertici della “PAN AMERICAN” , allora leader del trasporto aereo mondiale, invitarono la ROLEX S.A. a studiare un modello di orologio adatto a piloti e al personale in volo così da alleviare gli effetti del “jat-lag” e dotarli di uno strumento adatto ad indicare un secondo fuso orario. Da questo studio congiunto nacque il “GMT MASTER”, primo orologio della maison svizzera che riusciva a centrare ,con la semplicità di una sfera fatta a “freccina”, l’obbiettivo preposto.

It was 1956, the model had 6542 references, it is recognized immediately in the red blue ring ba-chelite (very brittle plastic resin) calibrated with 24 hours, and since then, through various forms of case, dial and balls, He has never left the lists rolex, we find the fact to this day always with his solid graduated ring, with his arrow and with his unchanging charm after more than 50 years.

The arrow with the red rod is nevertheless changed over time, the tip has become larger and the end of the stem is turned green; movements have been gradually more and more af fi born and perfected; the nut insert before
Bakelite became then aluminum and ceramic; quadrants that at the beginning were beautiful polishes have become dull and then return transparencies; Cases that did not previously have the winding crown protection and then had to tip and at the end they had rounded; all at the end leads to dozens of different models all small details sometimes an appreciable only by the most experienced.

Most fascinating, with the exception of the parent 6542 which inevitably is the "top" of the rolex gmt, are the 1675 born in 1959, replacing it, and accompany us to fi no pulse in the early 80s.
1675 GMT is the quintessential, and especially beautiful in the early years of production when it was equipped with dials "gilt" (shiny background) written with gold: few frills and lots of substance, robust and precise gauges, stainless steel case with gradevolissime shoulders of pointy protection fi no to the mid-60s, arrow GMT with small tip (freccino), a sportsmanship so simple that it can be worn on all occasions, and still very fascinating today as vintage connoisseur.

Parlavamo dei quadranti gilt: il sistema di fabbricazione era molto elaborato, la base veniva immersa in un bagno galvanico dorato, poi venivano applicate delle matrici a tampone dove dovevano rimanere le scritte e indici, successivamente altro bagno galvanico per dare il nero poi eliminazione dei tamponi (per questo le scritte e tutti i particolari dorati dei quadranti gilt sembrano tutti infossati) e finale trattamento con vernici lucide e applicazione del materiale luminescente sugli indici. Risultato finale estremamente gradevole e di una profondità ed effetto che difficilmente possono raggiungere addirittura i quadranti odierni. La totale lucentezza dello “zapon” (la vernice lucida di finitura) accostato allo stacco delle scritte dorate quasi incise, e al rilievo degli indici trattati con abbondante trizio, in certe angolazioni di luce, crea un effetto magico ed estremamente raffinato, che specialmente se accostato dalla patina che il tempo ha creato sulla superficie, da’ al collezionista, e non solo a lui, un emozione unica.

Molto varie le tipologie di quadranti gilt che si sono susseguite nei 1675 GMT : all’uscita ,nel 1959-60, troviamo poche centinaia di esemplari con minuteria continua ( così denominati perchè avevano un cerchio a bordo quadrante che congiungeva tutte le estremità degli indici dei secondi) con scritta ad ore 6 , Officialy Certified Chronometer (OCC), praticamente lo stesso tipo che “indossava” il loro “babbo” 6542; seguiran-no fino a circa il 1964 sempre i minuteria continua con diverse grafiche ma con scritta ad ore 6 Superlative Chronometer Officially Certified (SCOC), poi da fine ‘64 a fine produzione gilt ( circa 1967) scompare il cerchio che univa gli indici dei secondi ed appaiono nella produzione Rolex i quadranti detti a “minuteria aperta”. Gradevoli intermezzi si hanno nel ‘63 e ‘64 con quadranti gilt minuteria aperta con una piccola linea (underline o underlined) sotto la scritta SCOC a ore 6, specialmente molto rara ed apprezzata la gra-fica del 1963 underline minuteria aperta indici dei secondi lunghi, che in certi casi aveva la doppia scritta swiss sotto l’indice ad ore 6, queste ultime sembra siano state prodotte per la sola commercializzazione nel mercato d’oltre oceano. Esistono comunque anche underline con minuteria chiusa, anch’essi molto rari. I quadranti underline a detta di molti sembra fossero delle “prove” per vedere l’effetto della futura definitiva eliminazione della minuteria continua dai quadranti gilt , ma col tempo abbiamo imparato che era il segno di uso del trizio in luogo del radio per le parti luminescenti.

The rarity of GMT with gilt dials in excellent condition is well known by all: availability as the most dif fi cult are the OCC followed by the underline not to mention custom written or those with special logos.

l’anno 1964 è la svolta della produzione del 1675; infatti in quell’anno la cassa perde i caratteristici “corni-ni” per fare posto a spallette di protezione più stondate, inoltre a causa della normativa americana sull’uso di materiali radioattivi viene aggiunta alla scritta “swiss” sotto l’indice ad ore 6 la dicitura “T>25” ad indicare l’emissione di radiazione delle parti luminescenti del quadrante. Lo stesso diventerà come detto prima a “mi-nuteria aperta” sempre a finitura lucida e scritte oro fino quasi al 1968, quando farà posto ai classici quadran-ti “matt” (nero opaco) con scritte bianche, ma questo, come direbbero gli scrittori inglesi, è un altro discorso.

progenitor 6542, here in the latest version of 1958/59
of this watch there are two types of pre-quadrant (red lettering) and 4 normal types

01

Here a 1675 with an advertisement of 1961.

untitled-1

here the first model in 1675, 1960 ... OCC. remember that only by cash 600,000 can qualify for this type of dial ...

04

here is the first SCOC model, always the early '60s ... the result of production in 1960 / '61

05

in 1962 many dials had the so-called "exclamation point" in the rectangular index at 6 ... ..

06

the hardware dials continues continue till the end they manufacture horns in 1964, but in 1963 they are af fi ancati by transitional dial with no min continuous and double swiss (there are also single swiss) underline with (and without) .... these are the first tests of the next fi nal abandonment of parts closed in '65 and characterized by the position of the indices (buckshot) closest to the flange. I like to call these quadrants "long indices" ....

and now a small roundup of dials 61/62/63/64 ...

Remember that both the min min continuous open swiss are convissuti in the years 1963-'64 fi no all'entra-ta into force of the laws on radiation ... so you can find all types of dial fi no to the serial approximately 1,100,000. Another goes for cornino crates, which in my humble opinion are no fi lasted about 1.2 million.
The freccino anyway and always safe on all 6542 and all 1675 cornino cash.

19

since 1965 about changing the type of cash .... and the dials are uni fi cano all with short indices together with the written T> 25 ... .. these dials are mounted fi no to 1967 secure, you can also some specimens of '68. As to freccino, I would tend to make it "mandatory" fi no to 1967, but it is my hypothesis. basically this model has no obvious differences in the years of production (1965-1968 approx). Here the tropical '65 model with big arrow (replaced in years) as the insert which is known to be more recent (black insert only with the advent of 16750 IMHO).

Rolex 6239 the “Priest”

Rolex 6239
The evolution of the reference 6238 is called COSMOGRAPH to evoke the space-60s, and represents the new generation of chronographs pushers, similar to previous models, but with the difference that for the first time you use a graduated bezel to measure the speed.
The first set of COSMOGRAPH born with the reference 6239, and with serial numbers around 900,000 (1963); for the second, instead, these start at about 1 million (around 1964).

rolex_6239_priest

The latter has, in most productions, a bezel that presents second series, like the previous one, a scale to 300 units per hour, but with measuring intervals of a unit up to 100, intermediate 225 and 250.

rolex_6239_priest_01_02

The dial keeps ROLEX COSMOGRAPH written at the top, below the crown Rolex; down the dial has written the new T SWISS T, which will remain in use even on all subsequent production of dials for DAYTONA until after the mid-90s. The mechanical movement caliber Valjoux 722 custom is used.

Daytona 1987 FLOATING

Birth of the first automatic chronograph Rolex.
It will be a date to remember as a spark that gives the brand pentastellato a large revaluation of its entire production. This stems from the fact that the well-established home, unable to meet the demand of the market, is having to make long waiting times resulting in the rise in value, which continues even in our days.
This is the reason that now drives people to invest in something very lucrative, which is well established by many years.

We talk about the 16520 (first automatic chronograph).
The parent company after choosing the caliber (mechanism) to be used, namely the "Zenith El Primero 400", with 36,000 alternations and a frequency of 5 Hz, using a special-based molybdenum disulphide dry lubricant applied by a vaporizazione procedure, requiring specific equipment and a maintenance every two years, decided to draw deeply on the base caliber Zenith El Primero, so much so that necessitarono 200 changes so that he could be equated to its quality standards.
The first necessary interventions were performed to reduce the number of alternations (from 36000 to 28000) and decrease the frequency from 5 to 4 HZ. They mounted on a movement larger rocker that oscillated at a lower frequency, common to all the Rolex calibers of the moment. Rolex thus has simplified and improved the reliability of such a movement.

rolex_porcello_100k_bonanno_1

The rocker Rolex has four races in glucydur with Breguet spiral and a Microstella regulation system. Lubricants used for 4030 were those traditional media, those changes allow Rolex to recommend a review every four years, once almost twice the original size.
I movimenti 4030 montati sui Daytona prima serie seriale R ref.16520/3/8 hanno una numerazione compresa tra 10000 e 20000 (numerazione random che tiene conto anche del seriale successivo L). Le prime ghiere (per effettuare misurazioni di velocità) erano a 200 .
Un progettista di questo orologio, recandosi spesso a Parigi con un treno ad alta velocità, passava il tempo divertendosi a misurare la velocità con il suo Daytona 16520 (divertente il fatto che il suo essendo uno dei prototipi, non aveva il seriale e montava quadranti di prova). Il treno viaggiava a molto di più di 200km/h, quindi si rese conto che per il mondo moderno un misuratore con scala a 200 era insufficiente e propose di ridisegnare la scala con un limite più alto (400 uph la prima venne realizzata con intermedio a 225).
Another interesting feature is the dial Floating, you think produced in hundred copies for each version (gold, steel and gold, and steel; this last rarer than steel and stainless and gold types same as quadrants). This machining procedure was very long and complex, with exposure to high temperature furnace and then the application of the written. The latter depending on the drying level of the dial, when the written, has created the various levels of the floating (vitreous 1/2/3 level have been placed).

38d887f3-b67a-4962-90e1-e9891f5b641701

Today this type of watch from a value of about € 1,713 is the origin comes to about € 50,000. It is called the new Newman and with a number of pieces produced, about 100 repeat for the steel against the approximately 300 of a 6263 steel Newman (current value 300000), perhaps the future will have a large increase in value. I invite you to reflect on your future investment is always we will be at full disposal to accompany you on this journey, with the guarantee of our now historical seriousness.
