The Sellita SW200 is a Swiss watch movement used by many big Swiss watch brands because it’s cheaper and easier to obtain than the popular ETAs. It’s very similar to the ETA 2824 in terms of specifications and features.
It’s a precise and strong movement that can be used in sports or dress watches, and different complications can be added to it.
Sellita SW200 has been replaced by an improved version called the SW200-1, which has some modifications to reduce wear on the mechanism.
In this post, we will explain the operating characteristics of the Sellita SW200 and comparison of Sellita SW200 to other movements.

✚ A little history about Sellita Movement
Sellita is a Swiss watch movement manufacturer that was founded in 1950. Initially, the company focused on producing simple movements for alarm clocks, but in the 1970s, they started making watch movements.
Sellita became well-known in the watch industry for its high-quality and affordable mechanical movements. In the 2000s, Sellita began producing movements that were direct replacements for the popular ETA movements, which had become harder to obtain due to increased demand and restrictions on the supply of parts.
The Sellita SW200, which is a replacement for the ETA 2824, became particularly popular among watch brands due to its affordability and reliability. Over time, Sellita has expanded its range of movements to include more complex and high-end calibers, such as the SW500, which is a replacement for the ETA Valjoux 7750.
Today, Sellita is one of the leading Swiss movement manufacturers, producing a wide range of mechanical watch movements that are used by many prominent watch brands around the world.

✚ Sellita SW200 vs ETA 2824 Which is better?
Since a picture is worth a thousand words, here you can see the two movements in their standard version, that is, without any kind of premium decoration prior to assembly:
Both the Sellita SW200 and the ETA 2824 are Swiss-made automatic mechanical movements that are widely used in the watch industry. They are very similar in terms of specifications and features, and both are considered to be reliable and accurate movements.
In terms of which one is better, it is largely a matter of personal preference and individual circumstances. Here are some key differences between the two movements:
- Price: The Sellita SW200 is generally considered to be less expensive than the ETA 2824, which makes it an attractive option for watch brands that want to keep costs down.
- Availability: The ETA 2824 is produced by the Swatch Group, which has restricted its supply to third-party watch brands in recent years. This has led to a shortage of ETA movements and increased demand for alternatives like the Sellita SW200.
- Compatibility: The Sellita SW200 is designed to be a direct replacement for the ETA 2824, which means that it can be used in watches that were originally designed to use the ETA movement. This makes it a popular choice for watch brands that want to use a reliable, well-known movement in their watches.
Overall, both the Sellita SW200 and the ETA 2824 are good options for watch movements, and they are both widely used in the industry. The choice between the two ultimately depends on factors like price, availability, and compatibility with specific watches.

✚ Sellita SW200-1 vs SW200. How are they different?
The Sellita SW200-1 is an updated version of the Sellita SW200, with some modifications to improve its performance and reliability. Here are some of the main differences between the two movements:
- Anti-shock system: The Sellita SW200-1 has an improved anti-shock system that is more effective at protecting the movement from shocks and vibrations.
- Regulator system: The SW200-1 uses the ETACHRON regulator system, which is a more advanced system than the regulator used in the SW200. The ETACHRON system allows for more precise regulation of the movement’s rate.
- Power reserve: The SW200-1 has a slightly longer power reserve than the SW200, with a maximum running time of 38 hours compared to 36 hours for the SW200.
- Modifications for durability: The SW200-1 includes various modifications to reduce wear on the movement and increase its durability over time. This includes changes to the winding mechanism and the gears in the automatic winding system.
Overall, the Sellita SW200-1 is an improved version of the SW200, with modifications that make it more reliable and better suited for long-term use. However, both movements are widely used in the watch industry and are known for their accuracy and reliability.
All the information about the SW200-1 is available on the brand’s official website, including the plans and all the performance and precision data.
