Anyone who waits 10 years to service an OQ is risking a more expensive overhaul at the end of that period. The integrated motor can fail if the mechanical side of the watch loses its lube and produces more frictional resistance from the gear train.

Remember, the dial-side of the movement is essentially a 3035 gearworks. The IC, quartz oscillator and motor components provide the regulated motive force to drive that train. It is true that the unique OQ components don’t require the same schedule, but the dial-side works might need attention within 5 years.

Also, in 10 years gaskets and o-rings can fail.

What I recommend is having an OQ opened up 5 years after a full service (if no other reason pops up necessitating it).

Have the gear train inspected for presence of lube. Then have it pressure tested.

Thereafter, an annual pressure check and visual inspection is good to do. A certified watchmaker trained on OQ can do this - not suggesting it must be RSC-only.
