What are the differences between quartz and mechanical watches?

The functioning of a mechanical watch

Both categories of watches, both mechanical and quartz, serve to indicate time. The substantial differences concern their interior. Mechanical watches – the classic variant – have worked the same way for more than 100 years seiko presage limited edition.

First, every watch relies on the energy stored in it. In mechanical watches, this is usually generated by a winding spring contained in a barrel. The power reserve (i.e. the autonomy of a mechanical watch) varies according to the length of this spring, but usually reaches a duration of 40 hours. In some models it can last a few days or even a week.

Put simply, a gear transmits stored energy to an oscillating mass. This determines the rhythm of each watch, it is its beating heart. The oscillating weight of mechanical watches is usually composed of a balance wheel, escape wheel and anchor. The interaction between these components is what causes the ticking: a high frequency of the balance wheel produces a faster ticking, and vice versa. The movement of the second hand also becomes smoother as the frequency of the balance wheel increases. This usually corresponds to 28,800 vibrations per hour (A / h), or 4 Hz.

The impulse is generated by a quartz crystal, which begins to oscillate as soon as an electrical voltage occurs. This is the so-called inverse piezoelectric effect. The shape of the quartz crystal is similar to that of a tuning fork. The frequency normally corresponds to 32,768 Hz and is therefore much higher than that of a mechanical watch: this is why quartz watches are much more precise.
