Review of "Helium valve" of Noob POLM

[GenTLe 1,510]

In the last 2 evenings I serviced my NF POLM, this one (42mm):

 

and after the movement was back in shape and I was ready to re-case it, my attention was taken by the fake HE valve.

 

I have to say it has a very good construction!

It is equipped with 2 OR (rubber gaskets) and it's composed by a long screw that screws in the center of the crown and rotate with it, plus a spring that keep the external gasket against the case, but working over a washer to avoid damaging the or, plus a screw-in crown.

 

Here the valve disassembled (sorry for the bad pic):

 

And here 2 pics of the fitting place, 1st from outside of the case, then from the inside:

 

 

I have to say that I liked the way it has been realized, and I believe that with some silicon grease, it will be waterproof without the need of further intervention.

 

Cheers, GenTLe

Ahh, the helium escape valve, a great thing... unless you lose it like I did..

What a journey it was to get a replacement valve haha.

 

Nice review mate

They can indeed be waterproof without sealing these up
