Hello, As you can see on my "incoming" post, I'm new to the PO line. I have had 300m's before, and don't even remember what the HEV looked like. I'm noticing the HEV on the PO isn't perfectly flush with the case. I've unscrewed it and pushed it back as far as it can go. I bought this from an Omega AD, so I know it's genuine...it's just concerning me as I want to wear it under water, but certainly not with a valve open. It appears both the crown and HEV have almost a cone-like underside. The crown goes flush with the top of the case, but you can see the bottom impacting the bottom...which is fine. The HEV doesn't appear to be flush with either. Is this normal?
My 2254.50's HEV was not flush either. Although my blue SMP 2500 was more flush. I think it may be a QC issue. Sorry I can't speak for your model exactly. It should still have adequate WR.
