The **TIMEMORE C3S** has earned a near-unanimous reputation among coffee enthusiasts as the definitive budget manual grinder. At ¥9,584 on Amazon Japan (September 2026), it delivers an all-metal body, a precision S2C660 stainless steel burr, and 36-step grind adjustment — specs that would be unremarkable at twice the price.

This article explains the product features and the points to check before buying.

## TIMEMORE C3S: Specifications


| Specification | Detail |
|---------------|--------|
| Burr material | 420 stainless steel |
| Burr design | S2C660 (Spike-to-Cut) |
| Burr hardness | 55–58 HRC (5-axis CNC machined) |
| Hopper capacity | About 20–25g; manufacturer listings differ |
| Dimensions | φ52mm × H147mm |
| Handle length | 159mm |
| Weight | ~530g |
| Grind adjustment | 36 steps (internal) |
| Body material | Aluminum alloy (6063) + stainless steel |

The defining characteristic of the C3S versus its predecessor is the **fully metal body**. The original C3 used plastic internal framing around the spindle. The C3S replaces all plastic components with aluminum alloy throughout.

## C3S vs. Original C3: What Changed

| Comparison | Original C3 | C3S |
|-----------|------------|-----|
| Body construction | Aluminum + plastic frame | Full aluminum |
| Handle | Aluminum | Aluminum (same) |
| Burr | S2C660 | S2C660 (identical) |
| Grind adjustment | 36 steps | 36 steps |
| Hopper capacity | About 20–25g; manufacturer listings differ | ~20g |
| Approx. price | ¥7,980 | ¥9,584 on Amazon Japan (September 2026) |

Both models use the S2C660 burr. The C3S is an option for buyers who prefer all-metal construction; this difference alone does not establish superior taste or grind distribution.

<!-- HighlightBox start -->

If budget allows, yes. The improved rigidity, larger hopper, and superior build quality make the C3S the clear choice unless you're strictly constrained to ¥8,000.

## S2C660 Burr Performance

The S2C660 burr uses a **Spike-to-Cut** design: the burr first pierces the bean, then slices it — rather than the crushing action common in cheaper grinders. This two-stage cutting action reduces fine particle generation (fines) and produces a tighter particle size distribution.

Adjust the grind to the beans and brewing method. For espresso dialing, compare the ESP models, which offer finer adjustment increments.

<!-- HighlightBox start -->

The C3S is optimized for filter coffee. While it can reach fine settings, true espresso-grade consistency in the sub-200-micron range is outside its design intent. For espresso, the TIMEMORE C3 ESP series is the appropriate choice.

## Ergonomics and Grinding Feel

**Grip**
The φ52mm aluminum body fits naturally in one hand. Surface texturing is sufficient to prevent slipping during grinding. The ~530g weight provides stability without being cumbersome.

**Handle torque**
Grinding time depends on beans, grind setting, and rotation speed; no comparative timing measurements are reported here.

**Grind adjustment**
The C3S uses an **internal adjustment system** — the bottom cap is removed and the collar around the spindle is rotated. Less intuitive than external dial adjusters, but once set, the adjustment stays locked reliably. Mark your preferred settings with a marker for quick reset.

## Maintenance and Cleaning

The C3S disassembles easily: remove the bottom cap, pull the spindle out, and the burr assembly is accessible. No tools required.

**Daily**: Brush out the hopper and catch cup after grinding.
**Weekly**: Pull the spindle, brush around the burr teeth.
**Monthly**: Remove the burr entirely and inspect for buildup in the grooves.

Use a dry brush to remove grounds. Keep water away from the steel burrs and internal mechanism, and follow the supplied instructions for disassembly.

## C3S vs. C3S Pro vs. C3S Max

| Model | Key feature | Price |
|-------|-------------|-------|
| C3S | Standard | ¥9,584 on Amazon Japan (September 2026) |
| C3S Pro | Folding handle (portable) | ~¥14,980 |
| C3S Max | Larger hopper (~30g) | ~¥16,980 |

**Choose C3S** for home use brewing 1–2 cups at a time.
**Choose C3S Pro** if you travel or camp and want to bring the grinder.
**Choose C3S Max** if you regularly grind for 2+ people and want to do it in one pass.


**Pros**
- All-metal body at around ¥10,000 (Amazon Japan, September 2026)
- S2C660 burr produces consistent, low-fine grinds
- Easy to disassemble and clean
- ~530g weight provides grinding stability

**Cons**
- Internal grind adjustment takes practice
- Not suitable for espresso fine grinding
- 20g hopper capacity limits multi-cup single passes


## Final Verdict

The C3S combines an all-metal construction and an S2C660 burr. Compare its capacity, adjustment system, and current price with alternatives. This article does not establish taste superiority through comparative measurements.
