Rolex Replica Watches

The 1950s was an era in which Rolex had brilliantly asserted its dominance in the tool watch categories. In 1953, it launched the Submariner, which would become the most successful diving watch of all time. In 1954, the brand unveiled the incredible GMT-Master - later adopted by Pan-Am pilots to keep track of two time zones simultaneously while in flight, it was the world's first dual-time wristwatch.

But in 1956, Rolex wanted to create something different, a timepiece that asserted its ability in the world of ultra-elegant timepieces. Which, refracted through Rolex's sensibilities, did not mean a small, dandy's dress watch but a large (36mm), precious-metal-only chronometer with all its iconic robustness characterised by a screw-down crown, water resistance to 165 feet, and fitted with a precious-metal bracelet. The first references launched were the 6510 and 6511; they lasted only a year before being replaced by Rolex Replica Watches, which featured a Calibre 1055 with an all-new free-sprung balance wheel with Microstella regulated screws. This new movement resulted in the watches receiving official certification as chronometers; the dials now read "Superlative Chronometer Officially Certified" (instead of "Officially Certified Chronometer", as appeared on the 6510 and 6511).

The beloved 1800 family of watches was introduced in 1959. Of these, the 1803 is arguably the most famous. These watches were initially fitted with the Calibre 1555, replaced in the mid-1960s by the Calibre 1556, which featured a faster vibrational speed. In 1959, according to Rolex mythology, a total number of just six steel 6611 watches were made. Although other steel models are known, the tiny number from 1959 makes these the holy grail of Day-Dates. It is not clear whether they were commercially produced models or prototype watches made for internal use that eventually found their way to the market. I'm inclined towards the latter, but there is no definitive answer. In 1969, the Day-Date added a "concealed clasp" to its distinct bracelet, known as the President bracelet.

The 1970s was a period of strong technical advancement for the Day-Date. In 1972, the Calibre 1556 in the Day-Date became equipped with a hacking feature that meant the seconds hand would stop when the crown was pulled out. The watch was also fitted with a sapphire crystal around this time. In 1977,Rolex Daytona Replica Watches a new Calibre 3055 was fitted to the Day-Date, and the reference numbers for the watches grew by one additional digit: 18xxx. The key advantages to the Calibre 3055 were a 4 Hz vibrational speed for better autonomy from micro-shocks, and an all-important quickset function for the date. Before this, the date and days of the week could be adjusted only by turning the central hour and minute hands through the entire calendar cycle.
