Repair or restoration projects for tonneau‑case watches
1. Is this a genuine AP crystal?
No. It is a generic aftermarket replacement, not original, but matches the 25799 dimensions and profile.
2. Does this crystal fit other AP tonneau models like 25859?
Different references may have different crystal sizes. Measure your original crystal length, width, overall height, and edge thickness. The 25799 uses 25.5×21.5×2.2×0.7mm – do not mix with others.
3. What should I pay attention to during installation?
The flat bottom must sit flush in the case groove. Use a new gasket and UV adhesive, press evenly with a crystal press. Dome facing outward. Professional installation is recommended.
4. Will the original water resistance be maintained?
The 25799 is typically 30m water resistant. Proper installation with a new gasket can restore everyday splash resistance. A water resistance test is advised.
5. Is a gasket included?
Usually not. The sealing gasket must be purchased separately. Confirm with the seller.
