Price Index

We regularly track the monthly average prices for popular items. These are stored and used to form a price index showing the rolling monthly trend. The search terms we track are shown below, click to see the relevant graph. N.B. we don't manually tag items sold, instead relying on a soft search against the title, subtitle and description of the sale. This means that it is possible for prices to be distorted, e.g. by a specific strap being sold at a lower price affecting the trend for that watch model. Where there are sufficient sales this starts to become statistically irrelevant, however where there are only a few sales you will see anomalies.
