Rolex’s chronograph, the best rolex oyster cosmograph daytona replica watches, also became available in an 18 ct yellow gold version, certified as a chronometer. And these gold versions bore the fam ous phrase “Superlative Chronometer Officially Certified” on their dial, a rare achievement for a chronograph.
The rolex oyster perpetual cosmograph daytona replica evolved in 1965 with the launch of a version that introduced screw-down chronograph pushers instead of the pump pushers found on the original model. The screw-down pushers brought the finishing touch to the Oyster concept, and prevented the pushers from being manipulated accidentally. In testimony to its reinforced waterproofness, the name “Oyster” was inscribed on all the dials in addition to “Cosmograph”. Another new feature came in the form of a black Plexiglas insert for the tachymetric bezel. The white graduation increased legibility yet again.
An additional inscription appeared on some dials during the new Rolex chronograph’s early years on the market: Daytona. Initially limited to watches for the American market, it was most probably added at the request of the Rolex affiliate in the United States to mark the brand’s link, as Official Timepiece, with the Daytona International Speedway in Florida, and to symbolize the model’s close connection with the world of motor racing. The name gradually began to be inscribed on every Cosmograph dial, finally taking on its current form in an arc with red lettering above the counter at six o’clock.
With the arrival of quartz movements in the 1960s–1970s, Rolex nevertheless remained faithful to the mechanical watch and to the Cosmograph Daytona, preparing its future evolution. In 1988, the Daytona became self-winding. The brand opted for a quality, commercially available chronograph movement, which it then significantly modi?ed to meet its own requirements, replacing more than 50 per cent of the components with parts specifically designed for Rolex Daytona movements.
The rolex oyster perpetual cosmograph daytona 4130 replica watch update went far beyond technical features. The redesigned aesthetics formed the basis of the Cosmograph Daytona’s imposing and elegant appearance today. The diameter of its Oyster case was increased from 36 to 40 mm and included shoulders to protect the crown. The tachymetric bezel in metal was made wider and engraved with a 400-unit graduated scale. New hands, new hour markers, new counters within banded circles: the dial was modernized, while preserving its inimitable style and its signature “Daytona” in red letters.
Calibre 4130’s performance stems particularly from the use of a vertical clutch to activate the chronograph function, instead of the traditional lateral clutch. This new solution functions on the principle of two discs one above the other which work together by direct friction contact and offers signi?cant advantages – extremely precise starting and stopping of the perfectly smooth running chronograph seconds hand as soon as the pusher is pressed; and the ability of the chronograph to function for long periods of time with no negative impact on the precision of the Rolex Replica Watches.
