La Maison Rolex, come già molte volte abbiamo avuto modo di sottolineare, da sempre ha appuntato la sua massima attenzione sulle innovazioni tecniche atte a rendere l’orologio da polso fruibile in ogni condizione anche, e soprattutto, in quelle critiche maximum stress and risk for the same clock.
Without further digression on the history so much as on the developments that accompanied this great innovation we want this time to dwell only on a particular well-defined chest "Oyster" or its "base".
This was part of the watch has always been extremely sensitive about the foul and effective operation over time as any timepiece, and indeed, extremely sensitive as susceptible to leakage of any kind and type.
So the enlightened mind of Mr. Wildsorf designed and built the base "screw" taking, apparently inspired by a certain type of hydraulic valves in use at the time on the first submarine.
In this way the machine, per se, the interior of the watch is waterproof to all agents
outside.
In 1926, Rolex produces for the first time with a waterproof case back and screw-down crown, the Oyster chiamera'Rolex homes.
A brilliantly simple idea, almost unchanged today
The bottoms have an important role in the history of Rolex, they are often decisive for determining contemporary ', assessment and particularity'.
the dawn of the production went back
serial numbers stamped on the outside and References, which with time and wear and tear could result in termination. Inside
was instead punched the logo of the manufacturer and if the precious metal, the specific punches.
was later transferred to the reference clock in the bottom and the serial number in the middle of the loops on the chest.
Over the years took turns punching styles, with the lily, etc. arc often find the reference but not stamped engraved.
Possiamo trovare anche discordanze tra la referenza dell'orologio e
quella della cassa, tutte cose che se analizate con il metro dell'esperienza possono rivelare se pensate cosi' da Rolex o se adattate successivamente da chicchesia.
Incisioni particolari, sia esterne che interne, distinguono , identificano ed a volte fanno anche la differenza , dal punto di vista collezionistico, molti orologi sono completati solo se il fondello ha le caratteristiche identificative del modello in esame.
Mi spiego meglio , un sea dweller della prima serie
denominato Patent pending propio grazie all'incisione of that sentence on the back, a soldier must have a 5513/17 engraved award, a Comex idem.
For particular models even with a certain serial registration number, or any part thereof, should be reported
internally.
From 50 years until the early 70's, many specimens were punched in the date of manufacture.
all elements that can help us understand and identify
establish design criteria and originality 'of our Rolex
serve on a ride that you can see the history and evolution of Rolex, often made of contradictions. Porto
such a ride for the Cosmograph, the collectors for years wanted the watch with the same reference of back, giving a hypothetical correspondence to the non-replacement. What
that has' proved to be unfounded, without distinction on the Rolex Cosmograph rode all the piss
, early 6239 had the piss 6238, then we can find them with end caps 6241, 6242, inter alia, reference ever produced, with fondelli6262
6263, 63.65 and so on.
This was especially with the clocks changed depending on the reference ring or movement, while on watch with one variant of this is generally not succedeva.Questo obviously be established only after having seen hundreds of specimens so 'to establish a case study and evaluate eccezioni.Eccezione we can find in the early 1680 that could fit the bottom 5513, the same with 5513 or 12, until a recent history of the last 5513 even with serial numbers beginning with the letter L, which was equipped with a modern punch back with Rolex logo and the reference of 5512 production output more 'than 10 years earlier .
These examples should make us reconsider our passion with an optical non-mystical, religious,
our interest and 'face to a brand, a company that has a logic and business magazine that often does not correspond to any kind
reasoning than to business economics.
This obviously does not support all series
that only through real and virtual experience
we can somehow be determined.
I have collected many photographs of no order for that sensor from the bottoms
visualization I have divided into two parts.
Enjoy and Happy Holidays to all. Stefano
