I had asked a bit ago on why two features were as they were on the new 5000T. First was the O ring on the stem. Some other watch companies I believe do this so if the crown is out but not all the way, some WR ability is kept. Is that the case here? Second the use of tritrium. I know some don't like it, say it is ugly, but with those stainless markers anice neat vial would have gone well. Then lume whenver you want it. Please accept these as a Doxa owner would like to know.
