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.

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).

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.
