A quartz crystal chronometer is a clock that uses an electronic oscillator that is regulated by a quartz crystal to keep time. This crystal oscillator creates a signal with very precise frequency, so that quartz clocks are at least an order of magnitude more accurate than mechanical clocks.
- This is fast replacing the winding type chronometer
- It is completely solid state and crystal controlled.
- The rate is fairly stable
- Light and easy to carry
- Sealed to resist entry of dust and spray. Undergoes stringent tests for shock, vibration and extremes of temperature
