The winding crown and stem link you directly to your watch’s mechanical caliber. Over time, cross-threading, heavy force, or worn internal gaskets can cause the crown to spin freely, fail to screw down tight, or detach completely from the case. Leaving a damaged crown unaddressed exposes delicate movements to water vapor, dust, and rust damage.
Our Newport Beach watchmakers replace damaged winding stems and stripped screw-down tubes using genuine-spec parts. Whether your model uses a Twinlock or Triplock system, we restore crisp click-stops between winding, date-setting, and time-hacking modes, finishing every service with certified wet and dry pressure testing.

| Step-by-Step Service | Signs You Need It | Why It Matters |
|---|---|---|
| 1Inspect crown threads, gaskets, and stem condition using a 10x loupe. | Gritty feeling when unscrewing or tightening the crown. | Confirms true condition before opening the case. |
| 2Remove the old crown and stem; check the crown tube for wear or stripping. | Cross-threading – crown won’t engage smoothly. | Prevents further tube damage. |
| 3Replace with genuine Rolex crown (Twinlock/Triplock) and original-spec stem. | Visible gap between crown and case when tightened. | Restores correct seal geometry. |
| 4Replace the crown tube using Rolex-authorized tools, if damaged. | Crown pulls out too easily – stem may be worn or broken. | Rebuilds a secure winding connection. |
| 5Lubricate all new gaskets with silicone grease and install. | Fogging inside crystal after hand washing or rain. | Restores hermetic sealing. |
| 6Dry vacuum test followed by wet pressure test to rated depth. | Date change feels stiff or doesn’t click at midnight. | Confirms water resistance before the watch leaves the bench. |

I had such a wonderful experience at Newport Jewelers, and I especially want to recognize Jacob for his exceptional customer service! I absolutely did not want to be without my ring, but it needed to be resized. Jacob got me in right away and went above and beyond to make sure I wasn’t without it for long. He had my ring resized in record time, and I couldn’t have been happier with the service and care he provided. What really stood out to me was how accommodating, professional, and kind Jacob was. Customer service like that is hard to find these days! I had actually called another jeweler in the same plaza beforehand, and the person I spoke with was extremely rude and unhelpful. The difference in customer service was honestly night and day. I highly recommend Newport Jewelers and Jacob. If you want someone who genuinely cares about their customers and takes pride in their work, definitely see Jacob! ⭐️⭐️⭐️⭐️⭐️Posted on Google![]()

I had a wonderful experience meeting and doing business with Jacob. He was incredibly friendly, welcoming, and a pleasure to work with. I needed a ring resized, and the results were even better than I expected, especially considering how significant the size change was. The craftsmanship was excellent, and the ring came back looking brand new. I was also really impressed to learn that Jacob makes his own jewelry, which shows in the quality and attention to detail of his work. You can tell he takes a lot of pride in what he does. I’m extremely happy with how my ring turned out and would highly recommend Jacob to anyone looking for beautiful craftsmanship, quality work, and great service.Posted on Google![]()

I had two rings worked on by Newport Jewelers the first was a repair, stone replacement and smoothing down sharp edges making my ring more comfortable to wear. The ring is stunning, he cleaned and polished it Next I had him change the mounting of my gorgeous 12 carat vivid blue sapphire from a very old platinum ballerina styled ring. To a modern pave mounting. The ring is stunning when I saw it I got goose bumps and wanted to cry. I have never seen a more beautiful ring, and the best part is it is mine!!! Thank you so much I am so so very happyPosted on Google![]()

Never wear a watch with a loose crown or stripped threads near water. Stop by Newport Jewelers today for precision crown and stem replacement in Newport Beach.
Newport Jewelers provides on-site Rolex crown, stem, and tube repairs at our Newport Beach showroom, serving clients across Orange County.
Stripped threads on the crown or case tube from cross-threading prevent the crown from locking flush, which requires replacing the tube and crown to protect against water entry.
Store the detached crown and stem safely, avoid running water over the watch, and bring it to our Newport Beach workshop immediately to prevent dust and humidity from entering the movement.
Yes. Replacing the crown, tube, and internal gaskets reseals the case, followed by multi-stage pressure testing to ensure factory-level water resistance.
