  2. Mechanical watch - Wikipedia

    en.wikipedia.org/wiki/Mechanical_watch

    A mechanical watch is a watch that uses a clockwork mechanism to measure the passage of time, as opposed to quartz watches which function using the vibration modes of a piezoelectric quartz tuning fork, or radio watches, which are quartz watches synchronized to an atomic clock via radio waves.

    en.wikipedia.org/wiki/Automatic_watch

    By the 1960s, automatic winding had become widespread in quality mechanical watches. Because the rotor weight needed in an automatic watch takes up a lot of space in the case, increasing its thickness, some manufacturers of quality watches, such as Patek Philippe, continue to design manually wound watches, which can be as thin as 1.77 millimeters.

  4. Automatic quartz - Wikipedia

    en.wikipedia.org/wiki/Automatic_quartz

    Automatic quartz is a collective term describing watch movements that combine a self-winding rotor mechanism [1] (as used in automatic mechanical watches) to generate electricity with a piezoelectric quartz crystal as its timing element. Such movements aim to provide the advantages of quartz without the inconvenience and environmental impact of ...

  6. Tourbillon - Wikipedia

    en.wikipedia.org/wiki/Tourbillon

    In modern mechanical watch designs, production of a highly accurate watch does not require a tourbillon. There is even debate among horologists as to whether tourbillons ever improved the accuracy of mechanical watches, even when first introduced, or whether the watches of the day were inherently inaccurate due to design and manufacturing ...

  7. Movement (clockwork) - Wikipedia

    en.wikipedia.org/wiki/Movement_(clockwork)

    The term originated with mechanical timepieces, whose clockwork movements are made of many moving parts. The movement of a digital watch is more commonly known as a module . In modern mass-produced clocks and watches, the same movement is often inserted into many different styles of case.
