For most of Cheap Rolex Replica’s history, chronographs took a back seat to three-handed models. The company did produce some chronographs, but equipped them with third-party calibers that ticked in conventional, classic cases, not its well-known Oyster case. Rolex introduced its first Oyster-cased chronograph during WWII, but it was anything but a hit.
In 1955, Rolex launched its Reference 6234 chronograph. Neither “Cosmograph” nor “Daytona” appeared on the dial; the watch was simply labeled “Chronograph.” Rolex made about 500 of these watches each year until 1961, when the reference was discontinued.
Rolex first served as Rolex Replica Watches Daytona’s official timekeeper in 1962, one year prior to the debut of the Cosmograph Reference 6239. Rolex nicknamed this model “Daytona” the same year to emphasize the watch’s affiliation with the prestigious auto race. This timepiece was conceived expressly for racecar drivers, which explains why the tachymeter scale on the bezel is significantly larger than its counterparts on most other watches.
Rolex switched to screw-in push buttons with the debut of Reference 6240 in 1965. These seal the watch’s case nearly as hermetically as the Oyster models without a stopwatch function. The bezel of Reference 6240 was black with an acrylic inlay. Reference 6262, which was manufactured in one year only, 1970, and is therefore extremely rare, marked Rolex’s return to an engraved steel bezel and to unthreaded push buttons. The movement was also modified: Rolex raised the frequency of the Valjoux caliber from 18,000 to 21,600 vph.
This Rolex Replica movement was used in Reference 6264 from 1970 to 1972. Unlike the 6262, Reference 6264 had a bezel with an acrylic inlay and screw-in push buttons. The last references with hand-wound movements were 6263 and 6265, which were produced from 1971 to 1988.
In 1988, mechanical watches seemed like quaint relics from a bygone era because quartz technology had long since superseded them. That year, Rolex decided to introduce a self-winding Daytona. Rolex used Zenith’s El Primero movement, which had been introduced in 1969. Rolex Best Replica Watches made major changes to the El Primero, including slowing its frequency from 36,000 to 28,800 vph. This resulted in a longer power reserve and longer service intervals. Rolex renamed the movement the 4030.
In 2000, Rolex launched the first Best Swiss Replica Watches Daytona with an in-house movement. Caliber 4130, still used in today’s Daytonas, has 44 jewels, a 72-hour power reserve, and Kif shock absorbers for its balance and escape wheel. Vertical coupling assures a smooth start for the elapsed-seconds hand. The new movement, like the El Primero it replaced, has column-wheel switching.
The change in calibers is visible on the dial, where the running seconds subdial has been shifted from 9 o’clock to 6 o’clock and the centers of the elapsed-minutes and running seconds subdials are now positioned slightly north of the dial’s equator.
