Mechanical Watch, Based on Clockwork Mechanism

A watch using a clockwork mechanism to measure the passage of time as supposed to quartz watches functions electronically via a small batter or radio watches which are quartz watches synchronized to an atomic clock via radio waves. A mechanical watch drives by a mainspring which must be wound either periodically by hand or via a self winding  mechanism. The force of a mechanical watch transmits through a series of gears to power the balance wheel, a weighted wheel oscillating back and forth at a constant rate. Escapement releasing the watch wheels allows to move forward a small amount with each swing of the balance wheel, moving the watch wheel forward at a constant rate. The escapement makes the ‘ticking’ sound and that sound is heard in an operating mechanical watch. In the 17th century from spring powered clocks, the Mechanical watches evolving in Europe, appeared in the 15th century.

Quartz watches are more accurate than a mechanical watch and the mechanical watch requires periodic cleaning and calibration by a skilled watch maker. Mechanical watches nowadays have taken over the market mostly as a high-end product, purchased for their aesthetic  and luxury  values, for appreciation of their fine craftsmanship or as a status symbol, but long ago since the 1970 quartz watches taken over most of the watch market. All mechanical watches have five parts and they are a mainspring, a gear train, a balance wheel, an escapement and an indicating dial. A mechanical watch shows the calendar but some times faces complications to accurately count the dates, months and year. A mechanical watch works as alarm clock too and plays a bell or buzzer that can be set to go off at a given time. On military watches it is found that mechanical watch works as a hacker.

Nicolas fatio(or facio)de duillier and Pierre Jacob debaufre invented and and introduced jewel bearings around 1702 which are required to built a mechanical watches. Jewel bearinga couldn’t be used widely until the mid 19th century. Even until 20th century jewel bearings had become ground from tiny pieces of natural gems which were often found as garnet, quartz or glass jewela. Jewels likes Sapphire or Ruby were used in top quality watches. To grow artificial Sapphire crystals a process was invented in 1902. Jewels that are used in modern watches are all synthetic sapphire or (usually) ruby, made of corundum. (Al2O3), The advantage of using jewels are their ultrahard slick surface that has lower co efficient of friction with metal. In the properties of Sapphire and ruby as Jewel bearing there is no difference and the only difference is that different impurities have been added to change the color
