Replacement Helium Escape Valve Crown Compatible with Omega Seamaster Planet Ocean

Restore the appearance and operation of your watch’s helium escape valve assembly with this replacement helium escape valve crown, designed for selected Omega Seamaster Planet Ocean watches.

Manufactured for accurate fitment, this replacement component is designed to complement the case profile and valve assembly. It is ideal for replacing a lost, scratched, worn, stripped, or damaged helium escape valve crown during professional servicing or restoration.

Compatibility may vary between Planet Ocean references, case sizes, and production versions. Please confirm your complete watch reference, valve design, thread profile, and the following measurements before ordering:

• End head diameter: 1.4mm

• Stem diameter: 1.0mm

• Inner section diameter: 3.0mm

• Main body diameter: 3.9mm

Professional installation is strongly recommended. Water resistance and helium-valve operation are not guaranteed and must be verified through appropriate pressure and functional testing before the watch is exposed to water or used for diving.
