··Omega Qualified WatchmakerAt the Omega official warranty service in Brazil, they told me they have to replace the HE valve on older Planet Oceans when servicing, so it makes the service more expensive due to the part being replaced.
You unscrew the cap from the inside...the main tube that screw into the case remains in place:
Now the seal inside the cap and inside the tube can be replaced, and all the other parts put back:
The old style use a regular right hand thread on the screw that holds the cap in place, so there is only one screw slot in the ehad of the screw. The newer versions use a left hand thread, and to identify that they put 3 slots in the screw head - this is a new HEV assembly and the slots are visible through the unopened package:
Since Omega generally refinishes the case, they remove the complete HEV including the tube in the case rather than just disassemble it, to facilitate that refinishing. When they do that, they automatically replace the HEV with the latest style. There's no real "need" to replace it because of the valve itself, but they replace it because they remove it for refinishing - that's the most common reason.
If the watch is getting a paid service, this is included in the standard price - it should not be an extra charge at all. It is treated just like the crown, case tube, pushers, etc.
