The Seagull ST1901 is a mechanical movement that is manufactured by the Tianjin Seagull Watch Co. Ltd. in China. The company was founded in 1955 and is one of the largest watch manufacturers in the world. The Seagull ST1901 was first introduced in 1996 as a replacement for the ST19 movement. The ST19 movement was originally developed by the Swiss company Venus in the 1940s and was later acquired by the Chinese government in the 1960s. The Seagull ST1901 is essentially a clone of the Venus 175 movement, which was known for its accuracy and durability.

The Seagull ST1901 has since become a popular movement for watchmakers around the world, particularly those who specialize in the production of chronographs. The movement is known for its reliability, accuracy, and affordability, making it an attractive option for both watch enthusiasts and professionals.

The Seagull ST1901 is a hand-wound mechanical movement that features a column wheel and a vertical clutch. The movement has a frequency of 21,600 vibrations per hour and a power reserve of approximately 45 hours. The movement is made up of 19 jewels and has a diameter of 30mm and a height of 6.4mm.

One of the standout features of the Seagull ST1901 is its column wheel mechanism. This mechanism is responsible for controlling the start, stop, and reset functions of the chronograph. The column wheel mechanism is known for its precision and smooth operation, making it a popular choice among watch enthusiasts.

Another notable feature of the Seagull ST1901 is its vertical clutch. The vertical clutch is responsible for engaging and disengaging the chronograph function, which helps to reduce wear and tear on the movement. The vertical clutch also helps to ensure that the chronograph hand starts and stops smoothly, which is important for accurate timekeeping.

The Seagull ST1901 is often compared to other mechanical movements, such as the Valjoux 7750 and the ETA 2892. While each movement has its own unique features and benefits, the Seagull ST1901 stands out for its affordability and reliability.

The Valjoux 7750 is a popular movement that is often used in high-end watches. The movement features a chronograph and a date function, and is known for its accuracy and durability. However, the Valjoux 7750 is also known for its high cost, which can make it difficult for some watchmakers to use in their designs.

The ETA 2892 is another popular movement that is known for its precision and reliability. The movement features a date function and is often used in mid-range to high-end watches. However, like the Valjoux 7750, the ETA 2892 is also known for its high cost.

Compared to these movements, the Seagull ST1901 offers a more affordable option for watchmakers who are looking for a reliable and accurate movement. While the movement may not have all of the features of the Valjoux 7750 or the ETA 2892, it offers a solid foundation for watchmakers to build upon.

The Seagull ST1901 has even been used in space exploration. In 2003, the Chinese astronaut Yang Liwei wore a watch that was powered by the Seagull ST1901 on his historic spaceflight. The watch, which was made by the Beijing Watch Factory, was designed to withstand the extreme conditions of space travel, and the Seagull ST1901 helped to ensure accurate timekeeping throughout the mission.

The use of the Seagull ST1901 in space exploration is a testament to the reliability and durability of the movement. While most of us may not be traveling to space anytime soon, it's reassuring to know that the Seagull ST1901 can handle even the most extreme conditions.

Like any mechanical movement, the Seagull ST1901 requires regular servicing and maintenance to ensure optimal performance. It's recommended that the movement be serviced every 3-5 years by a qualified watchmaker.

During the servicing process, the watchmaker will disassemble the movement and clean each individual component. They will also inspect each component for wear and tear, and replace any parts that are damaged or worn. Once the movement has been cleaned and repaired, it will be reassembled and lubricated before being tested for accuracy.

To maintain the Seagull ST1901 between services, it's important to keep the watch clean and dry. Avoid exposing the watch to water or extreme temperatures, and store it in a cool, dry place when not in use. It's also important to wind the watch regularly to ensure that the movement remains lubricated and running smoothly.
