The same number means different things

Converting a setting
If a recipe quotes a setting for one of these grinders, read across for the equivalent on the other. Rows are spaced evenly by grind size, not by dial number — on a conical burr those are not the same thing.

The shape of each dial
Where the connectors bunch, that grinder’s dial is compressed and single steps count for more. Comparing the two shapes tells you which gives finer control, and where.

Timemore Chestnut S3
Dialing in the M47 Classic
A heavy, precision-built hand grinder with stepless adjustment and genuine espresso capability. The lack of detents means repeatability depends on your own reference marks — the settings here are targets rather than clicks.
Dialing in the Chestnut S3
Sits above the C-series with better burrs and a more solid feel. Its useful range genuinely extends further toward espresso than the C3, though a dedicated espresso grinder will still out-resolve it.
