FAQ

Q1: Is this a genuine ETA part?
A: Yes — this is a genuine ETA 2824-2576 Date Jumper, 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, classic automatic family). The part number 2824-2576 is the specific Date Jumper 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 Jumper do?
A: The Date Jumper (2824-2576) is a spring-loaded lever that performs two critical functions: (1) Position locking — it physically snaps into detents (notches) on the date disc, applying spring tension to lock the date disc in the correct position between jumps. Without this locking, the date disc would spin freely and the date display would be meaningless. (2) Advancement guidance — at midnight, when the date driving wheel pushes the date disc forward, the jumper releases from one detent and snaps into the next, producing the characteristic click and ensuring the date advances exactly one position. Without a functioning date jumper, the date cannot advance correctly and the display would be unreliable.
