Yes, that is unusual. There should be an index card with the serial number and the average daily rate. This is your service warranty card. It also includes the signature of the watchmaker and the signature of the QA person.
If you do not have it, you need to follow up.

It's normal that the movement serial number is not on the service invoice. For some reason, the service center will not enter the movement serial number on vintage pieces like yours in that box. That box will have the serial number for watches with the serial number engraved on the case or caseback. You may be able to just call the service center for the movement serial number for you watch. Its documented in their system. I hope this can save you some drive time and from voiding the service warranty as gbseq mentioned.
That's not my experience at all. I think every vintage watch I have sent to Bienne has had the serial number on the estimate at least...

I don't know how it was in the past but now days it's not on there. I've had to call the service center and even the customer service rep was surprised and didn't understand why they don't list it in the serial number box.
Bienne currently have my wife's 70s De Ville for a service, we received the watch and movement serial numbers on the quote.
