Please HELP - Rolex Daytona RSC triplock crown

[JacksonRain]

@padi56 @Tools @SearChart

Hi gentlemen and TRF, so I was unscrewing the crown for my timepiece that has recently gotten back to me from RSC. When I was unscrewing it, and not looking down, I noticed something that fell from my watch or from my hand. The crown was screwed on extremely tight when it came from RSC, although I'm not sure if that is relevant. When I unscrewed it I noticed what appeared to be a circle rubber piece. I didn't think much of it, but then later when I researched the triplock crown and gaskets, I came across would appears to be a Rolex part which appears to have fallen off when I unscrewed the timepiece.

I attached photos.

Is this indeed a part of the triplock crown or gasket?

Based on my review of pictures, if it is a Rolex part, the only way to see if it popped out and the triplock crown is actually missing something is to take out the case back and remove the stem.

Thanks to you guys and everyone in advance.

is that rubber o-ring torn/split?

No, I just started pulling it at either side and it is still intact, not torn. I should say obviously that the rubber ring that is photoed is the rubber piece that fell and landed on my desk is not the rubber piece that is still on the crown/stem.

Yes, I'm familiar, this is posted on Bob's watches. Doesn't necessarily help identify or affirm the part however.

Just take back to Rolex RSC and have them take a look.

[Kostas]

i mean, im no expert but wouldnt that o-ring have had to go over the crown to come out?

unless its to do with the pushers..

im sure Bas will know where its from, just hang tight until he chimes in.

Is there a chance that its not from your watch at all? lol

Lol. No, you are correct, indeed. I have no idea, the only thing I was thinking was that when I pulled it out, it came out or fell out when it wasn't in fact pushed in properly at all, and it wasn't even in the stem? I think that would be extremely unlikely though, especially when management was overseeing this repair, and the executive stated that there was literally a team dealing with this watch.

No, I have no idea what else it could be from.

Thanks man. I'll let Bas chime in. I don't want to have to go back to my ad or for it to go back to RSC unless I get some further input.

It looks like the largest one that is supposed to go around the tube, which is visible when you unscrew.

However, seeing that one is still in place, it cannot be that one.
Actually, if all were perfectly in place and the gasket that fell out is not split or torn in any way, than none of them could possibly have come out.

Three options here:

1. One of the gaskets is split and came out of the tube or crown when unscrewing, and because they are shaped you didn't see the split.

2. One of the gaskets was fitted improperly, making unscrewing hard, and the gasket came out in one piece.

3. This one is unlikely... An extra gasket that is not supposed to be there was somehow lodged between crown and tube and came out when unscrewing.


I'd still have a watchmaker look at this though.

Thanks Bas...I pulled it, stretched out. It's intact, so the o ring is not split.

So if I have them look at it, do they have to open it? They have to remove the case back and remove anything else?

So the fact that it was extremely tight may have played a role?

Caseback and then the stem, to see what actually happened.

Layman’s question.... is there a gasket to the chrono pushers? Did you unscrew them?

Yes, you unscrew the chrono pushers

I guess the question was might it have popped out from the pushers in case you unscrewed them? Guess you would have noticed...

No definitely did not come out from there

Pusher gaskets are way, way smaller.

[Andad]

There is no external gasket on the pusher.

I can’t see how a rubber ‘o’ ring that size could fit over the crown and in any event the ‘o’ ring is still present on the insert?

It’s a puzzle but if your Daytona (fresh from RSC) passes a pressure test, and is keeping time accurately, unless you want it opened up - maybe wait to see what else drops out...

How many years left on your warranty?

That’s a good deal of time to wait it out if you choose.

It doesn't appear to be an o-ring used inside at all.

I would go with an o-ring inadvertently caught in the crown which may account for the unusual tightness.

There is no place that a fully intact o-ring may have come from.

Indeed. It looks like the one that goes over the tube.
They sometimes stick together, but that wouldn't explain a random loose one in the crown.

Personally, I might not have that much experience yet, but I've never seen this happen before.

[csaltphoto]

I may be out of my depth here... But is there some way an "extra" o-ring might have become wedged between the crown and tube when they were putting it back together? Or is there an additional o-ring up in the crown that might have not been seated and gotten caught up in the threads? This would account for the difficulty in unscrewing it.

[lamnyc]

What the?!

[envuks]

Windfall! Toss that baby in the parts FS forum.

Rolex parts aren’t easy to come by. Perhaps an enterprising forum member may deem it a good investment

I just checked mine. No visible part missing on yours and given that the ring didn't come over the crown I think you're left with option 3. It was a sidecar part wedged in by the crown.

[lamnyc]

Wow. Your Daytona birth an O ring.

[Journeyforce]

I think somehow one of the waterproof gaskets came out. There are 4 gaskets in use here

The first is the Outer Waterproofness Gasket(seen attached to the crown tube)
The second is the 1st inner O-Ring (which is inside the crown tube)
The third is the 2nd Inner O-Ring (which is also inside the crown tube)
The fourth is the gasket in the crown

I think one of your inner O-Rings are missing now as looking at the diagram shown, it look like the gasket you have is an inner Crown Tube gasket

However I cannot see how an intact one could escape if the crown and stem are not removed. Nor do I see how a "free rider" gasket could have not only got there but how it actually would have be stuck in the crown/tube in the first place

Let me guess....RSC Dallas? If so, can send you contact info to expedite.
