As A930Rocket mentioned, When the numbers on the odo appear "jumbled" and not lined up correctly, it is a red flag that it's been clocked. The VDO mechanical /worm-drive odometers are pretty dead-nuts on when working properly (and un-tampered with) in my experience. I am sure there are exceptions, but usually when they fail, they fail. I have personally never seen/had one that just randomly skipped a tooth or spline on the gear stack. It may be a possibility or even common, and I am certainly no VDO pro (hence the "I could be wrong" part above). I just know that I have had several 911's (most being 3.2L Carreras), and every single one of them had odometers that lined up perfectly.
The other factor to keep in mind is that older 911 gauges are super easy to remove/replace. So, unfortunately, older 911s with "mileage discrepancies" are all too common. Unscrupulous dealers (or flippers) can simply source a correct VDO speedo/odo with lower miles and plug it in. Presto, that 160k mile car is now a 70k mile car! Or, they often try their hand at opening the existing one up to manually roll back the miles. The problem is that the way these things are built, it is nearly impossible to do so without cobbling it up, unless you have the proper tools/know how. So, that "DIY" roll-back job leaves the tell-tale jumbled number effect in most cases. Services like Carfax have helped curb a lot of it, but now a dealer can still roll back the miles to just after the last reported mileage "event" that shows up (which in some cases can still be a significant difference).
To the PO: Sorry for the hijack. If you want to put your mind at ease, I would suggest removing your speedo/odo and checking the crimp on the backside of the gauge. It should be readily apparent if the factory crimp on the bezel ring is still intact. If you are unsure, post pics and the braintrust here will tell you. It would be a good excuse to give the rubber gauge gaskets some lovin' anyway (glycerin, etc.)...
