A mechanical watch is one of the most fascinating machines ever created. In a space of a few cubic centimetres, hundreds of components work in harmony to measure time with extraordinary precision.
The 5 Fundamental Organs
1. The Mainspring
The energy “heart” of the watch. A thin steel strip coiled in the barrel that, as it unwinds, provides the energy to power the entire mechanism. Modern watches provide 48-72 hours of power reserve.
2. The Gear Train
A series of toothed wheels that transmit energy from the spring to the balance wheel, progressively reducing rotation speed.
3. The Escapement
The “regulator” that releases energy in controlled impulses. The lever and escape wheel create the characteristic “tick-tock” — actually 6-10 beats per second (21,600-36,000 alternations/hour).
4. The Balance Wheel and Hairspring
The precision “brain”. The balance oscillates back and forth, controlled by the hairspring. The frequency determines the watch’s accuracy.
5. The Dial and Hands
The visible part: hands connected to the gear train via the cannon pinion and minute wheel.
Why Maintenance Is Essential
Over time, lubricating oils degrade, gaskets lose elasticity and moving parts wear. A service every 5-7 years ensures every component functions perfectly.
