Description

Quick answer: This crown replacement for Rolex is an aftermarket stainless steel winding crown made to fit Rolex watches with a 6mm or 7mm crown. It comes in black, silver, gold or rose gold and is meant to be fitted by a watchmaker.

Why choose a stainless steel crown

Stainless steel is durable and corrosion resistant, which matters on a part you touch every time you wind or set the watch. Replacing a worn crown restores smooth winding and time setting, and the four finishes let you match the crown to your case or bracelet.

How to fit it

Crown replacement involves the stem and case tube, so we recommend having it fitted by a watchmaker rather than doing it yourself.

1. Confirm the size (6mm or 7mm) by measuring your current crown or checking your model.
2. Take the watch and the new crown to a watchmaker for fitting.
3. Ask them to check the case tube and gaskets at the same time to keep water resistance.

Frequently asked questions

Do I need a 6mm or 7mm crown?

7mm is the larger crown used on most sports models such as the Submariner, GMT-Master and Daytona. 6mm is the smaller crown found on many dress models such as the Datejust and Oyster Perpetual.

When should I replace my crown?

Replace it when the crown feels loose or wobbles, no longer screws down smoothly, has worn threads that will not lock against the case tube, or is badly scratched or dented.

Does the crown affect water resistance?

Yes. On a screw-down crown the crown seals against the case tube, so a worn crown can let moisture in. That is why the case tube and gaskets should be checked when the new crown is fitted.

What does the crown do?

The crown is used to set the time, adjust the date on date models and wind a mechanical movement.
