Original Orient spare part 30-997B (part number 966330997 ) from unused old stock (NOS). This is the ground packing/case gasket used in the Orient reference 429-26150 . This gasket ensures a proper seal between the case and the movement/case screw-on ring and is essential for restoring water resistance.
The part is unused, elastic and comes from long storage – ideal for overhauls and restorations of classic Orient vintage watches, where original gaskets are hardly available anymore.
