FAQ

Q1: Is this a genuine ETA part?
A: Yes — this is a genuine ETA 2824-195 Barrel Arbor, 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 part number 2824-195 is the specific Barrel Arbor 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 Barrel Arbor do?
A: The Barrel Arbor (2824-195) is the center shaft of the mainspring barrel — it is the rotating axis that the mainspring coils around during winding and unwinding. When the mainspring is wound, it stores energy by tightly coiling around the arbor; when it unwinds, it expands away from the arbor, releasing energy to drive the gear train. The arbor also transmits the rotational energy from the mainspring to the great wheel attached to it, which is the first gear of the power train. Without a properly functioning barrel arbor, the mainspring cannot coil or uncoil correctly, and the movement cannot store or release power.
