The escape mechanism works by transfering the force driving the gears to turn whether it that force is caused by trasfering the gravitational force from a weight or the force transformed from battery power into an oscillating mechanism which could be in the form of a pendulum, a spring, or a verge-and-foliot.
Each oscillating mechanism has its own frequency of oscillation and period of movement which are used to determine the amount of time each oscillation takes. The oscillating pieces work as the clock's counting mechanism and through the use of gears - or in the case of digital watches electronics - the clock is able to keep accurate time.
The way a spring loaded clock works is that it utilizes the potential energy stored in a wound spring to turn gears that are then stopped and restarted by the escape mechanism which makes the movements of the watches hands move at a certain rate. The main disadvantage with this type of design is that when the wound spring starts to get to the end of its potential energy store the periodicity of the second hand slows down until the spring is wound back up.
One of the main advantages of this style over one with a verge-and-foliot escape mechanism is that this clock has a spring in its escape wheel which gives the escape mechanism a specific oscillation rate. Just like the spring in the assisted escape wheel a pendulum has a specific frequency at which it travels which aids in the accuracy of the clock. But unlike the spring loaded clock, a weight driven mechanism keeps more accurate time because it faces less error when the weight gets close to needing to be reset.
I would expect a faster oscillation the tighter the spring. Save my name, email, and website in this browser for the next time I comment. Enter your email address to subscribe to this blog and receive notifications of new posts by email.

An early pendulum timepiece by J Bernard van Stryp, Antwerp, c. The controller is connected to the escapement — it controls the rate at which it allows the teeth to pass through. As each tooth passes the escapement, it gives the controller a little push to keep it going. A common controller is a pendulum, which is just a hanging weight — give it a push and gravity makes it swing, at a steady rate.
Because gravity is essentially constant, pendulums are great for good timekeeping. This is the part of the timekeeper that tells us the time, usually hands on a dial. A clock striking a bell gives an aural indication of time — sometimes from many miles away. Gilt-brass cased clock-watch with alarm by Hans Schniep. It has a single hour hand as a minute hand would be superfluous as the watch was only accurate to about 15 minutes a day. Speyer, Germany, c. These five elements apply to almost!
They can vary wildly, but are there if you look! Map Data.
