I presume that this is with respect to an older car with mechanical odometer. There are some tell-tale signs. A couple of tell-tale signs that something is or may not be right with the odometer:

- Gauge silkscreen coloration versus other gauges in the car. As the car ages, the silkscreen on the gauges typically fades somewhat over time. If the silkscreen coloration of the speedo is noticably brighter, the original speedo has possibly been replaced. The replacement could possibly be a new unit or a partially used unit. I would caution on using this alone. It is possible that a previous owner had the gauge silkscreen redone. This one is best used in conjunction with either of the two below.

- Non professional odometer adjustment. In order to adjust the odometer, one needs to get at the elements within the unit itself. To do this, the outer face ring needs to be removed. A non-professional almost always re-uses the face ring. In doing so there almost always is evidence of the ring being removed.

- Back side of gauge information. On the back side of the gauge there is information stamped on it. I do not believe that this information has stayed constant over the years. Find out what the information translates to and compare this to the information for a speedometer which is original for your car. This will take some detective work, but this board has folks which are a repository of almost never used knowledge about Porsches. Waiting to impart such knowledge for instances such as this.
