I am still thinking of buying the omega PO or the chrono diver as both really impressed me... I noticed that both has a helium escape valve which seem we can manually open it or close it.
I hv read somewhere that to a certain depth ( diving) & time , there will be a kind of pressure built inside the watch case which will explode the watch case .... I can see that my Seiko Monster doesn't have this valve so does it mean that the Seiko Monster will explode in the depth of 200 m ? or maybe it will only explode after 200m + ?
appreciate your comment
