FAQ

Q1: Is this a genuine ETA part?
A: Yes — this is a genine ETA 2824-2556 Date Indicator Driving Wheel, Made in Switzerland, brand new. It is an original factory part from ETA (Swatch Group), the world’s leading movement manufacturer. Not a generic or replica part.

Q2: How do I confirm this part fits my movement?
A: Confirm your movement is an ETA 2824, 2834, or 2836 automatic movement (11.5 lignes, the most widely used mechanical movement family in the world). The part number 2824-2556 is the specific Date Indicator Driving Wheel for this movement family. Common brand applications include: Omega Seamaster, Longines Master Collection, Tissot PRX, Certina DS, Hamilton Khaki Field, Tudor Black Bay 2824 variant, and many other watches using the ETA 2824 platform.

Q3: What does the Date Indicator Driving Wheel do?
A: The Date Indicator Driving Wheel (2824-2556) is the first active gear in the date mechanism chain. It receives rotation from the motion work (the gear train that drives the hands) and drives the intermediate date wheel, which in turn advances the date indicator disc. The date mechanism chain is: Motion work → Date Indicator Driving Wheel → Intermediate Date Wheel → Date Indicator Disc. The driving wheel continuously rotates — once per hour — and each rotation advances the date by one tooth position. At midnight, the accumulated advancement completes the daily date jump. Without a functioning driving wheel, the date cannot advance at all because there is no power link from the motion work to the date mechanism.
