automaattikojunasta
Automaattikojuna, also known as a self-winding or automatic watch, is a mechanical timepiece that automatically winds its mainspring using the motion of the wearer’s wrist. The mechanism relies on a rotating weight, called the rotor, which is coaxial with the watch. As the wearer moves, the rotor oscillates in response to gravity or centrifugal force, transferring energy to the mainspring through a gear train. This eliminates the need for manual winding while still providing the accuracy and tactile engagement of a traditional mechanical watch.
The design of automaatikojuna dates back to the late 19th and early 20th centuries when horologists sought
In terms of wear, these watches are prized for their minimal maintenance requirements compared to manual watches;
