Key Features
S2C 660 Spike-to-Cut Burr
Derived from TIMEMORE's flagship Chestnut X — spikes pre-break the bean before cutting, producing more uniform particle size and faster throughput than standard flat cuts
All-Metal Body — Zero Plastic
Full aluminium alloy construction internally and externally — no plastic supports or inserts that crack, flex, or wear over time; also eliminates static charge in the grounds bin
Dual-Bearing Shaft
Spring lock positions the inner burr; ball bearing holds the grind shaft — eliminates wobble for consistent grind distribution from espresso to French press
C3ESP — 30-Click Precision
0.0233mm per click gives espresso drinkers micro-level adjustment for dialling in extraction — 3.5× finer than the C3S for shots that demand exact grind size
C3S — 12-Click Versatility
Wider step size covers the full range from coarse French press to fine espresso — ideal for multi-method brewers who switch between techniques daily
Compact & Trail-Ready
52mm body, 25g capacity, and 530g weight — fits in a jacket pocket or top of a pack for freshly ground coffee at camp, on the trail, or travelling
