Note: I have retired my previous charts page, which can still be found here. The new chart is interactive and can be sorted and filtered to replicate many of the charts which were found on that page. While the old page contains old data, it still might be worth checking out for a better understanding of what stories this data can tell.

The horizontal axis identifies all observed serial number ranges by the first 4 (of 8) digits in a serial number. So for example 3829 encompasses all serials from 38,290,000-38,299,999. So each batch could hold up to 10,000 unique serial numbers.
The taller columns identify the most common “batches”, and the colors identify how many watches have been observed with movements in the given batch.
- To filter by one or more watch or case reference, click on the dots in the legend to select or deselect a given watch.
- To narrow down by a specific serial range or sort by number of observations, use the table below the chart.
- To print, export, or create a PDF, select the icon on the top right of the chart.
Tip: The best way to see a cal. 1040-only chart is to just “deselect” 378.0801ST from the chart legend, while the best way to see a cal. 1041-only chart would be to select only 378.0801ST and deselect everything else.

The following chart is like a histogram, but isn’t evenly spaced throughout the range of possible serial numbers.
