Crown tubing marring. Water resistance still ok?

[Silvio Mosiello]

Hello everyone I hope everybody is doing well. I just picked up my first day date 40 from a trusted dealer down here in Miami and I absolutely love the watch. One of the things that I did notice however, is when I am setting the time when I am unscrewing the crown, before it goes into the first Position, it feels like it gets a little bit not stuck, but there is more resistance that I’m used to.

Upon further examination, it looks as if there is a little bit of mooring on the crown tubing. The crown screws down perfectly fine and everything else about the watch is perfect I am just wondering is this something that I should be concerned about?

I really don’t want to send the watch out to have it worked on or to replace anything that doesn’t absolutely need to be replaced. Once again, this is only something you notice when you’re unscrewing the crown there is just more resistance than usual as if it almost wants to get stuck, but doesn’t, and then I just pops out as normal .

It is a 2019 day date 40. Please see photos attached and any advice as much appreciated. Thank you so much.

First off I can't see anything...

BUT. The real waterproofing is outside and inside the crown tube. And the gasket in the crown itself seals the top of tube. So as long as the crown screws down flush with the top of the tube you are good. You can always have the water resistance tested as well for peace of mind.

The Twinlock crown system your DD has. The red are gaskets. It's pretty ingenious

Agree with the above. No reason for concern.

Welcome!

I always found, on all my perfectly serviced watches, that the operation of the crown is very unsatisfying. But as it has been the same on all watches, I just try to operate the crown as little as possible as it makes me cringe each time.

Its fine the main seals are in the case as long as you can screw the grown down just finger tight no problem.

Nice addition - that’s 2 or 3 this year?

How did the YM situation resolve?

I agree with the others that your water resistance is still present. As for that resistance, the tube threads look fine.

But there are some steps you can take to see if there’s something in the crown’s threads (gunk or detritus). Use the soft plastic end of a dental brushpick and gently running water from the hot tap.




Pull crown to last position, invert the watch with crown down, hold it for 2-3 minutes under the gentle hot stream, and then rotate the brush end of the brushpick around the insides of the crown. Not aggressively - just to make 3-4 circumnavigations of the crown.

The hot water helps soften anything in the female threads inside the crown and the brushed fingers of the pick can pick up any foreign matter.

I will definitely try that thanks for the detailed response. I didn’t know that it would be okay to run water on the crown stem with the crown pulled out and the movement hacked. This year i have gotten this year ive gotten i believe 3 rolex and a tudor

I would strongly advise against putting any Rolex with the crown unscrewed near any water or steam. Dry floss will clean the threads just fine.
