Gaskets in V6F CrPO He valve?

[DR3M3L]

I got my second watch from Sora yesterday; a V6F CrPO. It looks great and doing business with Sora was just as good as the first time! Today I did some waterproofing and I noticed that the He valve had two gaskets on the stem but none in the crown of the He valve. Do all V6F/noob He valves look like this, or should I add a gasket in the crown? I did test the watch at 10 bar after waterproofing without any leaks, but I guess an extra gasket would improve the watertightness even further.

Anyone who have disassembled their He valve and have some input?

Not sure about v6f but noob is the same as gen. I expect v6f is the same too.

Haven't checked the He valve. But the crown on my V6 is missing the rubber gasket.

Should there be a rubber gasket? :helpsmilie:
I thought it was the crown called 'threaded crown with inside case tube threads' on this picture: http://www.esslinger.com/learning_center/watches/watch-crown-illustrations.jpg

Ah my bad. Yes the crown is threaded with inside casetube threads.

It looks like the noob in the pictures I've seen, but I haven't seen if other noobs or V6F's have a gasket in the valve-crown. My main concern with adding a gasket is if it will prevent the valve from being screwed all the way down.
