That means a receipt from a known to be good service provider, that can be tied to the watch in question. If the seller isn't able to provide that, then my advice would be to count on doing a service when the watch arrives when considering what to pay, and if that service isn't required, consider it a bonus.
I recently received a relatively modern Seamaster for service, that the seller had told my customer had been serviced "3 days before being put up for sale", but the seller didn't provide any proof, so the buyer sent the watch to me when it arrived for a once over.
I fully wound it and the balance amplitude in a horizontal position was just 240 degrees, so either it wasn't serviced, or wasn't serviced properly.
A visual inspection confirmed that the jewels were all pretty much dry:



And after cleaning, it's pretty clear that some wear has happened - this is the seconds wheel upper pivot:

And here is the reversing wheel pivot:

These were not the only parts needed, but given that this is a modern movement and these parts aren't expensive, this will only add around $130 to the service, so not a huge issue. For vintage watches I've paid more than that for one discontinued wheel, so there you need to be more careful to avoid a large financial cost.
