The ETA 2893-1 watch movement features a jewel-bearing rotor with 23 jewels and a detached manual wind. It incorporates an ingeniously simple power reserve display that utilizes the rotation of the barrel arbor to transfer movement to the hand and the rotation of the barrel to the tiny dial. This display effectively showcases the difference between the arbor and barrel rotations without the need for a complicated differential gear. Additionally, the ETA 2893-1 movement also includes functions such as automatic winding, sweep seconds, center seconds, and a power reserve display of 2 to 38 hours, although the actual run time is slightly less than the stated range at 34 hours.
