samgher Posted March 13, 2009 Report Share Posted March 13, 2009 Does anybody knows how to remove the helium escape valve (He) of a Omega Planet Ocean (UPO) 45,5mm? I bought the watch and opened the case back to check if waterproof. A big surprise inside!!! No gasket in caseback nor crowns. I search the entire internet to find generic gaskets without success. The case uses a non standard o-ring (40mm OD, cross section 1mm) and no references about the crown o-rings. I bought caseback gasket (original) from Ofrei and they told me that there are no available o-rings for Omega crowns because they sell the complete pieces (crown includes the gasket). I found an assortment of crown o-rings and i am trying to place them. It is a peace of cake to remove the stem (main crown), but dont know how to remove the crown of the helium escape valve (He). Any advises will be appreciatted!!! Quote Link to comment Share on other sites More sharing options...
