Mechanical watches are timepieces that operate through intricate systems of gears and springs, rather than relying on batteries. They are powered by the movement of the wearer’s wrist or by winding a crown, which stores energy in a mainspring. This energy is then released gradually to keep accurate time. These watches come in two main types: manual and automatic. Manual watches require the wearer to wind them regularly, while automatic watches wind themselves as the wearer moves. Mechanical watches are often appreciated for their craftsmanship and the artistry involved in their design, making them popular among collectors.
