Timemore C3 vs Timemore Chestnut S3
Two Timemore models whose numbers do not mean the same thing. Both count 36 clicks — and the same number is not the same grind.
| C3 | Chestnut S3 | |
|---|---|---|
| Brand | Timemore | Timemore |
| Scale | Clicks | Clicks |
| Dial range | 0 clicks – 36 clicks | 0 clicks – 36 clicks |
| Burrs | Conical | Conical |
| Espresso → filter | 7 clicks | 11 clicks |
| Filter → coarse | 11 clicks | 12 clicks |
The same number means different things
Both grinders use a clicks, which makes it tempting to copy a number straight across. Setting 18 clicks sits at grind index 53.2 on the C3 but 40 on the Chestnut S3 — far enough apart to change the cup.
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 C3
Timemore Chestnut S3
Dialing in the C3
The best-value hand grinder in circulation and the one most likely to be someone's first. Its range is usable across filter and immersion, with espresso possible but genuinely tedious. The C3 benefits more than most grinders from a few seconds of settling before you judge a shot or a pour — its distribution tightens noticeably once the burrs are warm.
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.
