Rolex 6240

This watch is to be regarded as an experimental model, a prototype to test new chronograph buttons with screw tightening.

The screw buttons are considered a kind of prototype, never appeared on spare parts catalogs Rolex. They have a characteristic grainy, later defined by collectors "striped". Their housing in the caseband is less pronounced compared to the models with pump keys and is easily visible looking at the back of the watch.

Anche la corona di carica Twinlock è differente da quella da quella utilizzata in precedenza, passando da 6 a 7mm di diametro. Questo orologio fu poco fortunato: nei quattro anni di vita raccolse frequenti giudizi negativi riguardo alle dimensioni della cassa e all’ingombro dei pulsanti cronografici a vite…giudicati colpevoli di rovinare i polsini delle camicie!

The definitive introduction of the screw provides buttons to Rolex a great advantage over its competitors. This function allows to immerse the clock even if the chronograph functions are disabled due to the location of the screwed pushers. This attracts buyers who flock to buy the Rolex chronographs in the world, thus ensuring the success of this model.

At first productions mounted a movement Valjoux 72B or 722, while on some models of the latest productions introduces the caliber 722/1, as always choosing the best the market could offer.
For many years now that the clocks have had major revaluations, for some time the people, seeing the results of the auctions and the market trend, they understood that the watches are also a form of investment.
All this makes it more and more these valuables and difficult to be found.
We enclose the clock and, as is our usual photos, we illustrate with a graph the trend of the value in the various years, bringing the cost of the object had at the origin and the price that corresponds to today, also points must be noted over the years he has re-evaluated.

The watch in question, for a standard model, had a cost of 120,000 lire in 1965, corresponding to today's purchasing power of € 1238.75.
So far it has reached a value of € 60,000, about 50 times higher than the original figure.

This shows the great appreciation and then big investment that this watch made.

Rolex 16528 Floating

As previously described in the inherent Rolex 16520 Floating, We're talking about 300 porcelain (another name often used) products.

We draw some news from the previous article, to remind you how much work has been used for this watch.
The house mother chose as a gauge (mechanism) to use the "Zenith 400 El Primero", with 36000 alternations and a frequency of 5 Hz, using a special-based disulphide dry lubricant Molybdenum applied by a vaporization process, which required specific equipment and a maintenance every two years. The basic caliber Zenith El Primero was then processed deeply, so much so that necessitarono 200 changes so that it could be compared to the quality standards of the brand.

The first, necessary, interventions were carried out to reduce the number of alternations (from 36000 to 28000) and decrease the frequency from 5 to 4 HZ. They mounted on the movement a larger rocker that oscillated at a lower frequency, common to all Rolex calibers of the moment, so as to simplify and improve the reliability of such movement.
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.

The 4030 Daytona movements mounted on the first serial ref.16520 series R / 3/8 had an numbering between 10000 and 20000 (numbering random which also takes account of the next serial L). The first nuts (to perform speed measurements) were 200.
Uno dei progettisti 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 (uno dei prototipi che, in quanto tale, 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).

& Nbsp;

Un’altra interessante caratteristica è il quadrante Floating, si pensa prodotto in cento esemplari per ogni versione (oro, acciaio e oro, e acciaio; questa ultima più rara rispetto alle tipologie oro e acciaio e oro uguali come quadranti). Questo procedimento di lavorazione era assai lungo e complesso, con esposizione a forni ad alte temperature e poi l’applicazione delle scritte. A seconda del livello di essiccazione del quadrante nel momento in cui sono state poste le scritte ha creato i vari livelli di floating (porcellanati 1/2/3 livello).

It's always too little one on which we can shed some light. What to add: Today this watch is called the Paul Newman of automatic, and you think of Paul Newman with screw keys and manually wound, they were produced around 300, with values ​​ranging from a low of about 300,000 Euros to a maximum approximately 500,000 euro for normal versions, while other extremely rare, for different characteristics, also values ​​above 1,000,000 Euros.
As already mentioned, automatic porcelain were produced approximately 100 stainless steel, 100 stainless steel and gold and gold-100. To date, the market valuations are extremely lower than those of manual winding ancestors, the rest is up to your feedback.

We attach photos and the clock, as is our usual, we illustrate with a graph the trend of the value in the various years, bringing the cost of the object had at the origin and the price corresponding to the present, also points must be noted in the years has appreciated.
The watch in question, for a standard model, had a cost of about 20 million lire in 1989, corresponding to today's purchasing power of € 20,643.82. So far it has reached a value of € 50,000, more than double the initial amount.

Rolex Sea-Dweller

The prototype of the Sea-Dweller, "Dweller of the sea", the Rolex was never put on the market, but handed over to the dive company or individual divers in late '67 and early '68 because they were tested. Next, it was produced and put on sale in different variations.

The era advertising booklet wrote:
"The underwater exploration has grown dramatically in recent years.
Per raggiungere delle profondità sempre maggiori e per poter lavorare rimanendo in acqua, l’uomo ha costruito delle campane, dei cassoni, persino delle casse. In questi abitacoli, gli specialisti vivono in un’atmosfera artificiale, costituita da certe miscele di gas, generalmente con una forte percentuale di elio. Le molecole particolarmente sottili e leggere di queste miscele si infiltrano lentamente nell’orologio, senza pertanto alterarne il funzionamento. Inversamente, al momento della decompressione dovuta alla risalita, la miscela di gas deve poter fuoriuscire rapidamente per non provocare l’esplosione dell’orologio. Per questo motivo, la Rolex ha munito di una valvola brevettata “gas escape valve” (valvola di sfogo) il suo modello più recente Oyster: il cronometro Sea-Dweller, garantito impermeabile fino a 610 metri di profondità”.

The pentastellato brand has always invested a lot on water clock, reaching its peak, in fact, the Sea-Dweller.
By careful research and continuous innovation that distinguish the house, a Rolex watch has long been recognized not only as a reliable object, but as a real investment, which boasts revaluations also quite important over time.

Oyster This in particular is still produced with the technical characteristics today's technologies. The new model Sea-Dweller, with red writing, which is so required to purchase it you have to be willing to pay even more than the list price.
Further confirmation of the Rolex guarantee that, thanks to his work, continues to represent.

We attach photos and the clock, as is our usual, we illustrate with a graph the value of the trends in the various years, bringing the cost of the object had the origin and today's consideration, so as to emphasize how over the years It has appreciated.

Rolex 16528

In this article we will describe one of the last Daytona Gold product before using a mechanism made entirely by the parent.

For many years Rolex is a company at the top in the watch industry, and its products give great satisfaction to each user: someone buys it for love, some for investment ... some for both reasons.

It all started in 1908, when Hans Wilsdorf wanted his timepiece wore a short name, easy to remember and to pronounce in all languages, and that it could be harmonized with the dials and movements.

Regarding the choice of the name, he recounted:

“Ho provato a combinare tutte le lettere dell’alfabeto, in ogni modo possibile. Avevo così a disposizione qualche centinaio di nomi, ma nessuno mi piaceva. Fino a quando una mattina, mentre viaggiavo sul piano superiore di un omnibus trainato da cavalli, lungo la via Cheapside nella City di Londra, uno spiritello mi ha sussurrato all’orecchio: Rolex”.

La casa madre a sempre cercato di offrire il massimo della qualità, utilizzando quanto di meglio il mercato potesse offrire. Parliamo, ad esempio, del 16520, il primo cronografo automatico. La maison sceglie come calibro (meccanismo) lo “Zenith 400 El Primero”, con 36000 alternanze ed una frequenza di 5 HZ, e utilizza uno speciale lubrificante a secco a base di Bisolfuro di Molibdeno applicato mediante un procedimento di vaporizzazione, che richiedeva attrezzature specifiche ed una manutenzione circa ogni due anni. Decide quindi di elaborare profondamente il calibro base Zenith El Primero, apportando ben 200 modifiche affinché potesse essere all’altezza dei propri standard qualitativi.

I primi necessari interventi vennero eseguiti per ridurre il numero di alternanze (da 36000 a 28000) e diminuire la frequenza da 5 a 4 HZ. Montarono sul movimento un bilanciere più grande che oscillava ad una frequenza più bassa, comune a tutti i calibri Rolex di quel periodo, semplificando e migliorandone così l’affidabilità.

Il bilanciere Rolex ha quattro razze in glucydur con spirale Breguet e sistema di regolazione a microstella. I lubrificanti usati per il calibro 4030 erano quelli fluidi tradizionali, tali modifiche consentano a Rolex di consigliare una revisione ogni 4 anni, tempo quasi doppio rispetto al calibro d’origine. Qual è la conseguenza? La fornitura di meccanismi Zenith per la Rolex, in relazione con la maggiore richiesta di Daytona Zenith, rende questo orologio un oggetto raro e, come già detto per molti prodotti della casa, una vera opera d’arte di grande valore.

& Nbsp;

Unique for its special and extremely rare for the request, quickly makes splash in the market value much higher figures of the original value. Are now many years that all this makes it a guarantee of stability, a beautiful object and one of the best investments that the market can offer.

One of the most interesting news in recent years is undoubtedly the RM030 of 2011, which provides a gear device able to eliminate risks due to the overvoltage of the mainspring, automatically disengaging the rotor of the charging system when the spring has reached the ideal voltage (ie 50 hours of autonomy, as indicated on the dial) and performing the recoupling when the power reserve reaches 40 hours.

Another masterpiece is the RM 056 Felipe Massa Sapphire: fully transparent and the first watch-case to be built entirely of sapphire. It is a limited edition of 5 units at a price of US $ 1.7 million, and was declared best watch of 2012 the exhibition "Salon Internacional de Alta Relojeria" in Mexico City.

The RM 11 is instead a titanium chronograph, lightweight and anatomically like everyone watches the fashion house, always meet the quality standards that the house now ensures long time.

Rolex 4313: a guarantee

As is well known research by Rolex has always been aimed at finding the best she could offer, and in this article we will describe in a few words the story that led to doing the brand pentastellato a guarantee, speaking of chronographs and in particular the 4313 Rolex pink gold.

& Nbsp;

& Nbsp;

Fino alla fine degli anni ‘90 la scelta del meccanismo impiegato nei cronografi vede il trionfo del Valijoux, della nota casa svizzera. Questa preferenza è frutto di attente valutazioni e continue modifiche, volte ad un costante miglioramento a livello qualitativo e funzionale. Nei primi orologi si trovano infatti movimenti con alternanze (oscillazioni del bilanciere) più basse, che aumentano nel corso degli anni per dare la possibilità di leggere un tempo più frazionato e quindi più vicino a quello reale, avvicinandosi alla precisione dei cronografi al quarzo attuali.

& Nbsp;

& Nbsp;

The first chronograph Rolex is 2021, mono button with case of important dimensions and base-proof cover, which I could appreciate at first hand the wonderful processes typical of pentastellato brand.
The house has since produced many chronographs, sometimes with small differences, while maintaining the same quality standards in the years of extreme reliability.

& Nbsp;

& Nbsp;

The 4313 Rolex Chronograph Rose Gold 1954 (serial 999 000) is a wonderful clock moved, like all first chronographs, by a beautiful Valijoux 23 with 18,000 alternations.
The spider of the loops forms features make this object a real work of art that, due to the revaluation over the years has a significant added value.

& Nbsp;

We attach photos and the clock, as is our usual, we illustrate with a graph the value trends over the years.

Patek Philippe: a name two people.

It all starts in 1838 with the foundation of "Patek, Czapek & Cie" in Geneva by the entrepreneur Antoni Norbert de Patek, an immigrant from Poland, and the watchmaker François Czapek, immigrant from Czekia.
In 1844 Antoni Patek, founder of the Maison, knows the French watchmaker Jean-Adrien Philippe in Paris where the latter presented his pioneering and convenient system setup time and charging the watch via the crown, which will replace the 'use of a separate key.
In 1845 François Czapek decided to leave the company to continue on its own, and the company name is changed to "Patek & Cie".

It is produced the first pocket watch for ladies: the timepiece is decorated with miniature of a rose. The company manufactures its first pocket watch with minute repeater and was awarded the patent for the Patek clock with charging and focusing mechanism per hour through the crown.
In 1851 Jean-Adrien Philippe officially joined the company, which changed its name to "Patek Philippe & Cie."

At the Great Exhibition of London, Queen Victoria is among the admirers of the first timepiece in the world without a key, the first of which had been patented by Jean-Adrien Philippe in 1845. The Queen of Great Britain and Ireland invests in a pocket watch enamel powder blue with floral decoration in diamonds cut in pink.
The pendant with clock dial on demand and brooch apparently had belonged to Queen Victoria.

Patek Philippe is among the first watchmaking maison to export to the US and enters into an alliance, still thriving with Tiffany & Co. in New York.
In 1881 it was awarded the patent for the precision control system, and in 1889 Patek Philippe & Co was awarded the patent for the perpetual calendar mechanism for pocket watches.
Nel 1932 "Ancienne Manufacture d'Horlogerie Patek Philippe & Cie, S.A." viene acquistata dai fratelli e Jean Charles Stern, già di proprietari un'azienda produttrice di Ginevra has Quadranti. Da allora "Patek Philippe S.A." è di rimasta un'azienda property familiare.
It was with this style of management, "a family", the parent company continues its efforts to ensure buyers an extremely reliable product with low production revalued over the years.
A Patek Philippe is forever and we find ourselves to be guardians and pass it down to our posterity.

Today we want to deepen on an extremely beautiful and complicated watch, the Patek Philippe 5004.
In 1995 we have the launch of the Ref. 5004 with 27-70 gauge. The basic movement Lémania with split-seconds chronograph and perpetual calendar CHR 27-70 Q is introduced in Ref. 5004 which remains in the collection for 16 years, until 2011.
A Patek Philippe is awarded a Swiss patent for the isolation mechanism of a split-seconds chronograph.

& Nbsp;

& Nbsp;

Simple shapes, the right size, the extreme complications collected in such a small space and so well divided, make this splendid object an engineering laboratory, a work of art.
Many people who are going to search for it: who does it for investment, some for the pleasure of it, or for both reasons. Manages to please everyone and, with some difficulty to find, continue to give us all this.

We enclose a photograph of a Patek Philippe 5004 G and a graph showing the value of the trend over the years.

The price expressed in euro sales in 1995 of 5004standard, it refers to the purchasing power of today.
