A hard gasket in the crown?

[Khan]

I realized a hard gasket in the crown prior to cleaning. Is it possible or is it just worn out? Im used to see black gaskets. 

[AndyGSi]

Probably just gone hard with age.

[Khan]

So it should be replaced, right?

[AndyGSi]

Yes it needs to be replaced.

You need to replace the complete button.

That assumes you can actually buy the correct crown. If it's signed by someone who doesn't sell parts or isn't around anymore, I'd wager you could find a suitable o-ring of some sort. May even be able to find something at your local hardware store. OD, ID, and durometer (hard) are the specs you need. Won't be exact, but should be functional. If you want to hunt a little harder, small rubber washers also exist, and will be better. You may be stuck with a bag of 100 though.

From the picture it looks like in addition to the gasket you have the metal and off? In other words the piece of metal that holds the gasket in seems to came off which would have to go back in place in order for replacement gasket the work properly.

It looks like a waterproof crown may be a link like this might be helpful

Then on the main page for crowns they also sell crown gaskets. But as your crown is disintegrated a gasket really will be a waste of time and be better to buy another Crown.

Not sure what you mean by disintegrated?

The metal washer is a press fit and designed to be removed when replacing the rubber washer.

The ones that I've seen are usually not designed to be removed. Usually people replacing the gaskets use pointy little tools and reach down inside and pick the gasket out they do not disassemble the crown.

The Flat Micro Ring Rubber Washers will never be able to be picked out through the steel washer hole.

So all waterproof crown's can be disassembled?

[AndyGSi]

It depends how they're constructed but if they're like the OPs then I've never seen any other way to swap it.

When I go to work today I will ask how many of the crowns disassemble for changing the gaskets as that's something they do On a regular basis and to be honest I don't pay attention to what they're doing when they're changing the crown gaskets so maybe they do disassembled but I will ask today find out how many disassembled.

[Khan]

I might replace the crown with a new waterproof crown. The current crown is the original anyway and has dents so on. 

[JohnR725]

I did ask at work today and they do not disassemble the crowns.

I'd like to know then how they get a flat rubber washer out and back in?

[Malocchio]

They sure can be sometimes changed without breaking the crown open. You have to cut the old o-ring to pieces with a screwdriver or something and then manage to get the pieces out. New (greased) o-ring can be poked in if it's not too big for the gap. Seiko 6105 divers cannot be done this way, the o-ring is way too big.

Below is a link to a trick for these which clearly shows there's no other way but to disassemble it.

I've done this to one Willard crown. I also tried it on a smaller Seiko crown but although the washer came out easily it was smaller and thicker than the one in Willard and couldn't be domed. Or at least I wasn't successful. Some people cut the washer in a lathe and make a new one.

If it first you don't succeed, try, try again. (Or just get a bigger hammer).
