To fix this you are going to have to open up the case and get into the detailed workings. It is pretty delicate stuff in there and parts do wear out. You may prefer to get it to a specialist to recondition.
If you do want to sort it yourself you will need to remove the chrome bezel and glass and then undo the two screws on the back of the case. Remove the mechanism complete. It does come out, but may seem like it won't, especially if it has a trip mileometer fitted.
Inside, resist the temptation to dismantle or disturb anything - if the needle is working then don't tamper with it. It is all very sensitive.
The odometer is driven via a plastic (nylon?) worm gear that links to a reciprocating lever. This in turn operates a pawl and ratchet wheel that turns the 1/10 mile wheel. There are tiny cogs between each wheel that move the subsequent wheel around by 1 numeral for every full revolution of the one next to it.
Your problem is most likley to do with the plastic pawl or the ratchet wheel that it operates on. There is a small spring that holds the pawl against the ratchet and these have the habit common to all springs, of disappearing from the known world. Sometimes it is as simple as the pawl slipping off to the side of the ratchet wheel. Other times it could be that one or both of these parts is worn. You need to look pretty closely to see the condition. As I said, this is delicate stuff - getting into the realms of watchmaking!
good luck,
Guy
