Watch case sizes by year

Across 5,369 case sizes introduced from 2002 to 2026, the median case width was 39.6 mm in 2002, peaked at 42 mm from 2009 to 2014, and was 40 mm in 2026.

Millimetres, by the year a case size was first produced. The shaded band holds the middle half of the sizes introduced that year.

How this is measured

The figures come from the watchmis.com catalogue. 27,199 of its 47,400 published references record both a production year and a case width; 26,023 of them were first produced between 2002 and 2026.

A collection sold with hundreds of dial variants would outweigh every other watch of its year, so references are not counted directly. Each combination of brand, collection, and case width is counted once, in the first year it was produced: 5,369 case sizes in all. The median is the middle of those sizes, and the middle half runs from the lower to the upper quartile. The shares of large and small cases are shares of the same case sizes.

This describes what the catalogue holds, not what was sold. Years with fewer than 40 case sizes are left out, widths outside 10–70 mm are treated as recording errors, and a brand that is well covered in one year weighs more in that year than one that is not.
