Rolex oyster perpetual day date 40 replica also carries on its dial the calendar functions that inspired its name. The Day-Date is also an Oyster Perpetual, which means that it is equipped with the “Perpetual” self-winding system with a free rotor patented by Rolex as of 1931 – a system later adopted by the whole watchmaking industry. This calendar display, prompted by the founder of Rolex himself, was unique at the time for a wristwatch. With the Day-Date, Hans Wilsdorf designed a high-prestige Oyster Perpetual that offered a particularly useful function for people in positions of responsibility: a clear and legible indication of the day and date at a glance.
Essential information required for scheduling, arranging meetings, rolex day-date 40 replica watch or signing and dating contracts, which made the Day-Date the perfect watch for decision-makers. Its calendar was quite different from the standard calendars of the day. Like the first “tool watches” created by Rolex from 1953 on the basis of the Oyster Perpetual – such as the Explorer, or the Submariner – the Day-Date stood out for the eminently practical and legible presentation of its functions. Until then, wristwatches displayed the date by means of a hand which pointed to a date marking at the edge of the dial. More sophisticated calendars, known as “complete calendars”, added the month and day shortened to three letters in small windows at 10 and 2 o’clock on the dial, together with a large moon phase at 6 o’clock.
The Day-Date owes its reputation and prestige first and foremost to its exceptional horological qualities. It benefits from all the innovations that have given Rolex watches their place at the summit of the contemporary art of watchmaking. Its principal characteristics are, in fact, summed up on the dial: Oyster Perpetual, Day-Date, and Superlative Chronometer Officially Certified. Each of these markings highlights one of the features that make this a truly exceptional timepiece.
The rolex day date replica winding mechanism makes use of a half-moon-shaped oscillating weight that turns freely through 360° to transform every movement of the wrist into a source of energy to automatically wind the watch. An ideal complement to the Oyster case, it eliminated the need to unscrew the crown every day to manually wind the watch, thereby avoiding any risk of compromising the water proof ness of the case. The Perpetual system furthermore provides a constant supply of energy to the movement, for signifi cantly greater regularity and precision. With the Oyster Perpetual, Rolex laid the foundations of the modern waterproof and self-winding wristwatch. The Day-Date, when it was launched, brought the modern wristwatch to its apogee.
A compelling example of avant-garde watch-making technology, this rolex day date 40 ice blue replica watch self-winding mechanical movement is entirely developed and manufactured by Rolex. It is backed by 14 patents and a number of innovative technological solutions relating not only to component design but also to processes involving new technologies that push back the limits of current production methods. More than 90 per cent of the movement parts have been redesigned and optimized, from those that produce and store energy (self-winding module and mainspring) to the regulating organ responsible for precision (oscillator), the gear train and the escapement. The escapement, which transmits the impulses required to maintain the oscillator’s steady beat, is enhanced by a major innovation
