Waterproofing SD HEV Valve?

[george84]

Is the HEV valve on the super sea dweller (swiss eta version) functional? As in, does it need to be sealed in order to waterproof the watch as a DSSD would need to be? Or is the valve on the SD purely for show?

I'm pretty sure they're functional. Therefore, to insure maximum WR, you can take the movement out and epoxy the back of the valve on the inside of the case.

Or you could have the watch checked for WR- 4-5 atms say, no leaks and you're good in the swimming pool or for light snorkeling work.

Generally, SSD's do fairly well when it comes to WR. Typical leaks are

1. Crystal and crystal gasket

2. Crown and case tube and gaskets

3. Case back and gasket

4. HE Valve
