The mechanical movement is a type of watch mechanism that is powered by a mainspring working through several gears and levers. Unlike quartz movements, mechanical movements don't rely on battery power. Instead, mechanical movements fall into two categories: The first one is the manual movement, and it is wound by the mainspring using hand power, whereas the automatic movement is wound due to the wearer's wrist motions.
Mechanical movements, made from intricate craftsmanship, are embraced by most watch enthusiasts as a characteristic of the traditional artistry of watch making.
