This is a generic TAG Heuer steel screw-down crown, sized at 5.1mm in diameter and 4.1mm in height, with an M0.90 tap (0.90mm thread diameter).
Designed as an aftermarket replacement for TAG Heuer watches requiring a screw-down crown system, this set includes the matching crown tube for a complete repair solution.
The screw-down mechanism doubly ensures water resistance with an extra seal that becomes watertight when the crown is screwed down, while also preventing accidental function changes .
Stainless Steel – Corrosion-resistant and durable, ideal for sports and dive watches.
Screw-Down Waterproof Design – Compresses the sealing gasket when tightened, providing reliable water resistance.
Complete Set – Includes crown and matching tube – no additional parts needed for repair.
Precise Dimensions – 5.1mm diameter, 4.1mm height, M0.90 thread – fits select TAG Heuer models.
Generic Aftermarket – Non-original but manufactured to OEM specs for direct replacement.

1. Is this a genuine TAG Heuer crown?
No. It is a generic aftermarket replacement, not original, but matches common TAG Heuer screw‑down crown sizes and includes the tube.
2. How do I know if it fits my watch?
Measure your original crown diameter (5.1mm) and height (4.1mm), and confirm M0.90 thread. Some TAG Heuer models (e.g., Aquaracer, Formula 1) may fit.
3. Will the original water resistance be maintained after installation?
Proper installation with a new gasket can restore factory water resistance (typically 100-200m). A water resistance test is advised.
4. What should I pay attention to during installation?
Press the tube into the case using a tube press or adhesive. Clean threads, apply silicone grease. Professional installation is recommended.
5. Is a sealing gasket included?
The crown typically includes one gasket. The tube base may require an additional gasket – purchase separately if needed.
