Watch of the Week- Carl von Zeyten CvZ0024RWH
Our watch of the week is the Carl von Zeyten CvZ0024RWH. It features a brown leather strap with crocodile embossing. The case is made of rose gold-colored stainless steel. What makes this automatic watch special is that the balance wheel can be seen from the front on the dial, as well as from the back through a screw-down mineral crystal case back. The intricate dial has black Roman numerals and rose gold-colored hands. Overall, it can be said that this men's watch from Carl von Zeyten looks very high-quality and elegant.
Automatic watches with open balance wheel
Open balance wheel
Balance wheel is the short term for a balance-spring oscillating system, as used in mechanical watch movements. The oscillating system serves as the regulating mechanism for small timepieces, especially wristwatches and pocket watches, but it is also used in alarm clocks or wall clocks.
The idea of using the balance wheel together with a hairspring was developed by Christiaan Huygens following a proposal by Jean de Hautefeuille; in 1675, he was granted a French patent for it.
The oscillating system consists of the actual balance wheel or balance and the hairspring (with collet and roller). The materials used include steel, spring steel, spring bronze, brass, but especially special alloys, which should be as non-magnetic as possible (influence of external magnetic fields).
An open balance wheel means that the dial usually has circular sections where the balance wheel can be seen from the outside. This often gives it a high-quality look and is visually very appealing.
Automatic watch
An automatic watch is a mechanical wristwatch in which the mainspring is wound automatically in small steps by a rotor as the wearer moves their arm. Early models of automatic wristwatches were sometimes equipped with a pendulum oscillating weight instead of a rotor.
Simple manual winding via the crown initially made it difficult for the more expensive automatic pocket watches to establish themselves, although they had existed since around 1770. In 1922, the French company Leroy created the first wristwatch with an automatic movement, driven by a pendulum oscillating weight, but it was never sold. John Harwood, a British watchmaker from the Isle of Man, is known as the inventor of the automatic watch. His idea, developed from 1914 onward, led to a patent application in Switzerland on October 16, 1923, which he received on September 1, 1924. The Rolex Oyster Perpetual from 1931 is considered the first functional automatic wristwatch with a one-way winding rotor. The invention of automatic winding with rotor and reverser for pocket watches is attributed to Abraham-Louis Perrelet in 1775.
