1. Is this a genuine Jaeger‑LeCoultre crystal?
No. It is a generic aftermarket replacement, not original, but matches the Q1972472 dimensions and includes a gasket.
2. What is the advantage of the “no step” design?
A step‑less crystal has a smoother edge, requiring less complex alignment during installation. Together with the gasket, it forms an effective seal, suitable for specific case groove designs.
3. Will the original water resistance be maintained after installation?
Proper installation with the included new gasket can restore everyday water resistance (typically 50m). A water resistance test is advised.
4. What should I pay attention to during installation?
Clean the case groove, place the new gasket, then the crystal (dome outward). Press evenly with a crystal press. Professional installation is recommended.
5. Does this crystal fit other AMVOX models?
Different references may have different crystal sizes. Measure your original diameter (40.8mm) to confirm.
