Helium valve: could you please explain how it works
Many watches include this valve to allow deeper water resistance. Does it spontaneously works without any intervention, or do we have to push the "He marker" ? Thanks for your explainations cheers, Patrickh

Dear Moderator, dear BDLJ, many thanks for all your explanations
I think your teaching lessons will help some of us. Best regards, patrickh
Hello patrickh!
Hello patrickh! Glad it helped. I always find it wonderful that the PuristS are such a diverse bunch with so much knowledge to share. Thanks again to BDLJ for the info! so Patrick, are you planning a diving trip now? -MW
not yet, but maybe next year with the chronopassion dextro sub

Really interesting explanation

Thanks for the explaination...
the sales guy at the AD was completely wrong..but I aint about to correct him...

He should know the product he is selling. Few things irritate me more than a salesperson who doesn't know his own material. Unfortunately that is the normal state of affairs at several major watch retailers these days...
