The Rolex Caliber 3035 is today regarded as one of the best and most reliable mechanical calibers ever made by Rolex. The Caliber 3035 had a successful production run that lasted for 12 years starting in 1977 and was eventually replaced by the successor, Caliber 3135 in 1988. What further enhances the iconic status of the Caliber 3035 is the fact that it was the first high-beat caliber that Rolex launched. Rolex did this by increasing the beats from 19,800 to 28,800 BPH – meaning 8 beats per second – in order to increase the accuracy of the caliber. The increasing of the frequency of the movement also meant a visible difference in the form of a seconds hand that looks more like it sweeps rather than ticks. The Caliber 3035 was the first-ever automatic caliber to feature a quickset date function. Previously, the wearer had to wind the time forward 24 hours to change the date, which of course makes setting the date rather time-consuming. But with the quickset function, you can easily change the date by pulling out the crown to the date-setting position and changing the date separately without changing the time.
