Mens C5 Malvern Automatic Watches from Christopher Ward

The Malvern Automatic Watch was Christopher Ward's first watch and set the standard for everything that followed. From the timeless elegance of the understated face and case design to the famous Swiss made ETA 2824-2 Automatic movement there is no compromise in its excellence. But it is the sum of the parts, however, that has caused such a stir amongst watch connoisseurs the world over.

If you don't yet own a watch with an automatic movement, then let this superb timepiece be your introduction to the true art of horology.

Automatic winding

A rotating weight, set into motion by moving the wrist, winds the spring barrel via the gear train of a mechanical watch movement. Automatic winding was invented during the pocket watch era in 1770 by Abraham-Louis Perrelet, who created a watch with a weight swinging back and forth (that of a pocket watch usually makes vertical movements contrary to a wristwatch). The first automatic -winding wristwatches, invented by John Harwood in the 1920's, utilised so-called hammer winding, whereby a weight swung in an arc between two banking pins. The breakthrough automatic winding movement via rotor began with the ball bearing Eterna-Matic in the late 1940's, and the technology hasn't changed fundamentally since.

The Eterna-Matic is the grandfather of our own automatic movements. Eterna became ETA and is now owned by The Swatch Group.

Automatic Watch

An Automatic Watch is a watch whose mainspring is wound by the movements or accelerations of the wearer's arm. On the basis of the principle of terrestrial attraction, a rotor turns in an Automatic Watch and transmits its energy to the spring by means of an appropriate mechanism. The system was invented in Switzerland by Abraham-Louis Perrelet in the 18^th century.

Automatic watch

From Wikipedia, the free encyclopedia

The name Automatic watch comes from the point that, instead of the owner having to wind the watch to power, the watch winds itself "automatically" when worn regularly. To accomplish this, the watch contains a fan-shaped rotor (weight) within the watch case. The normal movements of the user's arm and wrist cause the rotor to pivot back-and-forth on its staff and the staff is attached to a ratcheting winding mechanism inside the watch. Movement of the user's arm is thereby translated into circular motion of the rotor that eventually winds the mainspring. The fully-wound mainspring in a typical watch can store enough energy for roughly two days while motionless. Most automatic watches can also be wound manually by turning the crown (a notable exception is Seiko's wide-ranging line of watches based on the company's 7S26 movement, which cannot be hand-wound).

On some automatic watches the rotor is visible through a transparent case back, called a display back or exhibition back. In these cases the rotors are often engraved or decorated in some way.

For people who do not wear their watch every day, watch winders are available to store automatic watches. A watch winder is a device that can hold one or more watches and moves them in circular patterns to mimic the human motion that keeps the self-winding mechanism working. A mechanical watch should be kept wound and running as much as possible to prevent its lubricants from congealing over time, which diminishes accuracy. A full service (which involves disassembly, cleaning and re-lubrication) should be performed at least every five years to keep the movement as accurate as possible.

A more recent evolution of the BI uses a self-winding mechanism to charge a battery or capacitor which in turn powers a quartz movement. This automatic quartz arrangement provides the accuracy of quartz without the need to replace the battery or capacitor until it reaches the end of its life, which may be decades.
