Q1: Does this crystal fit all Datejust 36 references?
A: It fits five‑digit Datejust 36 references such as 16233, 16234, 18238, 18946, 18038. Not for newer six‑digit references (e.g., 116233) or Datejust 41.
Q2: After installation, the date appears doubled under the cyclops – what should I do?
A: Double vision usually means the cyclops is not precisely aligned with the dial‘s date window. Remove and reinstall, or mark the window position on the case before pressing.
Q3: Can I use the supplied gasket directly?
A: Yes, but compare its thickness with the original. If the original gasket is still pliable and undamaged, it may be reused – however, it is recommended to replace the gasket every time the crystal is changed.
