What the number is good for
Very little, on its own. 20 mm being the most common size does not make it likely for your watch: the four sizes above cover barely seven watches in ten, and the remaining three carry sizes running from 12 to 30 mm.
The distribution is useful for a workshop deciding what to keep in stock. For one watch on one wrist, only the measured number for that reference means anything.
