1. Is this a genuine ETA/Incabloc part?
Yes, this is a genuine Incabloc shock protection component used in ETA 2000 movements, made in Switzerland. It is not an aftermarket or generic copy. Boley GmbH lists the shock-absorbing block for ETA 2000/2000-1 calibers as an INCA system component .
2. What is the difference between 3024 and 3025?
The 3024 and 3025 references likely cover the upper and lower shock-absorbing blocks or different variants within the ETA 2000 family . Please verify your specific movement and position before ordering.
3. What is the function of the Incabloc system?
The Incabloc system uses a lyre-shaped spring to suspend the jewel setting. When a shock occurs, the spring allows the jewel setting to deflect, letting the stronger shoulder on the balance staff absorb the impact rather than the delicate pivots . After the impact, the springs guide the parts back to their original positions .
