Time
Time is one of the elementairy measurements with other units such as distance nowadays depending on a correct time measurement. Time is measured using the oscilliations of an atom such as Cesium, Rubidium or Hydrogen. These time standards are atomic clocks. Together with my wife we have a number of clocks in the house of which some are related to navigation and positioning while others are just that, clocks.
The instruments in our collection can be divided into:
- Chronometers and other time measurement devices for accurate measurement of time onboard vessels
- Mechanical clocks for indicating time at home or the office
- Quartz / electronic clocks for indicating time at home or the office

Mechanical clock
A mechanical clock uses the movement of a spring or pendulum to keep a regular time. The pendulum design is the oldest design after solar and water clocks.

Electronic precision...
The electronic precision clock is designed to keep very accurate time. There are two basic types, the atomic clock (not in my collection) and the clock as a function of a navigation system where the computation of position is 4D (it includes an accurate time relative to the base system, for example GPS)
