The Sellita SW-200 is a popular Swiss automatic movement that has gained widespread use in the watchmaking industry since it was introduced in 2003. It is based on the ETA 2824-2 movement, which is one of the most well-known and respected mechanical watch movements in the world.
The SW-200 is known for its reliability, accuracy, and ease of use. It is used in a wide variety of watches, including diver's watches, dress watches, and even pilot's watches. The movement has 26 jewels and operates at a frequency of 28,800 vibrations per hour (vph), which gives it a smooth and accurate tick. It has a power reserve of approximately 38 hours, which means that it can run for a full day and a half without being wound.
One of the key features of the SW-200 is its hacking function, which allows the wearer to stop the second hand while setting the time. This is a useful feature for people who need to set their watch to a precise time, such as pilots or divers. The movement also has a quick-set date function, which makes it easy to adjust the date without having to turn the hands back and forth through the entire day.
In terms of construction, the SW-200 is made up of high-quality components that are designed to last. The movement has a robust and reliable winding system, and the balance wheel is made of Glucydur, a high-precision alloy that is resistant to temperature changes and shock. The escapement is made of Swiss-made Incabloc shock absorbers, which help to protect the movement from impacts and drops.
Overall, the Sellita SW-200 is a reliable and accurate automatic movement that has gained widespread use in the watchmaking industry. It is a suitable choice for a wide range of watches, from casual to formal, and its hacking and quick-set date functions make it a convenient choice for people who need to keep track of time with precision.
