Rolex uses Automatic or mechanical movements, they did make a quartz in the early days of quartz, but no longer.
A mechanical watch operates without a battery, or sunlight. The watch needs input from the owner to tell time for the time to be continuously told. The smoothness of the seconds hand is dependant on the how each second is split, the more splits per second, the smoother the hand seems to flow. A 10hz watch looks pretty darn close to a Grand Seiko Spring Drive, the Spring Drive has no interruption of flow, it has no tick. The issue with 10hz watches is that they are not as reliable as a slower beat movement, as you go down in Hz, you go up in robustness and also get a longer power reserve - all things being equal. I am simplifying this - so don't expect this paragraph will suffice to make you an expert.
Automatic watch: tells time by controlling the unwinding of a coiled linear mainspring to show hours , minutes, seconds, day and date (some). This watch type can often be hand wound from the crown to build up the power reserve and then when worn the watch - presuming the wearer has enough arm movement in a 16 hour period - the watch will continue to run after you take it off for 36 - 60 hours depending on what movement is in the watch. Another type of automatic watch movement can only be wound up by forcing the winding rotor to oscillate (spin) by movement of the watch in a gentle movements - like holding the watch in your hand and pretending it's actually a snifter of brandy. For this type, turning the crown of the watch does nothing.
Mechanical winding watch: same time telling principle as above, but all energy stored in the mainspring must be generated by winding the crown of the watch, usually every day - recommended to be done at the same time each day. Swinging this type of watch does nothing to add more power to the mainspring, it winds down without any care about your air drum solo.
Quartz watch: needs a battery or sunlight to function, often 1 discrete tick per second but I have a Heuer 2000 Quartz Chronograph that beats in 0.5 second intervals. The Bulova Precisionist line beats at a pace that makes it look completely smooth, but battery life is only about 1 year.
I hope this helps?
