ÔťÜ How Does It Work?

As it is the same mechanism, most of its parts are interchangeable, and the specifications are almost identical.

Therefore, it is also an automatic movement with a bidirectional rotor mounted on a ball bearing.

It also includes the Novodiac shock protection system from Incabloc to protect it from shocks and falls, as well as the Etachron regulator for easier and more precise movement adjustment.

The precision and power reserve specifications are the same, and it also features manual winding and hacking seconds.

ÔťÜ Time and Date Setting

The adjustments are made very similarly to the ETA 2824, and they only differ in the date where the 2836-2 has an additional adjustment.

  • Time: pull the crown outwards to the outermost position (2 clicks or jumps), the second hand will stop due to the stop-second or hacking function. Then simply rotate it to reach the desired time.
  • Date: pull the crown to the first position (1 click). Then rotate it clockwise to advance the date and counterclockwise to change the day of the week. Do not adjust the date when the hands are between 9 PM and 3 AM to avoid damage to the mechanism.
  • Manual Winding: without pulling out the crown, rotate it clockwise. For watches with a screw-down crown, it is necessary to unscrew it first in the opposite direction before winding.
