A study in mechanical patience

A machine
for noticing.

Seven gears, one mainspring and a small brass heart that has been keeping the same promise since 1948. Wind it, stop it, listen to the escapement — the time is still the time.

The train

Power leaves the barrel through the centre wheel, the third wheel and the escape wheel. Each reduction is a small act of restraint. Nothing is direct; everything arrives on time anyway.

The sound

Six beats per second, 518,400 a day. A quiet room makes them audible, which is the whole point of owning a mechanical object in a digital house.
