Also called a gear train, the wheel train is the one connecting the mainspring with the escapement. As such, it serves two functions — one is to transmit the force from the mainspring to the balance wheel, and the other is to drive the timekeeping hands. This component is the one that allows the user to wind the mainspring and to move the hands to set the time. As mentioned above, the force from the mainspring is being transferred to this part. The said force powers the balance wheel to oscillate back and forth at the same amount of time.

It, therefore, serves as the timekeeping element of the mechanical watch. The escapement mechanism, which is composed of the escape wheel and the pallet fork, also serves two functions.

Today, the Rolex Day-Date is available with the days of the week in 26 different language options.

While Rolex pioneered the modern day-date watch in the mid-fifties, calendar complications had been in use in pocket watches since the late th century. By the end of the decade, the movement had become a common feature in many watches, though it had to be manually adjusted each day. Rolex began to really establish its dominance in this complication, when, in , founder Hans Wilsdorf introduced the Rolex Datejust , claiming it as the first wristwatch with a self-changing date.
