So to answer your question there is no hard and fast rule, except to say that the Achilles heel for a 31xx movement is known to be the lubrication requirements of the bearing arrangement for the oscillating weight which is crucial for the Automatic winding mechanism.

Thanks, bud! Appreciate the info.
Does anyone want to admit how long they have had their 31xx without service, and yet it still runs fine?
Is there any hard evidence that anyone can do actual damage to the movement if it goes too long without service. I know that some advocate service every 10 years, while others advocate not to send it in until it ceases running accurately.
