Self-winding mechanical movement beating at 21600 vibrations per hour, with a power reserve up to timed 37 hours/untimed 45 hours.
The ST19 movement can be regulated to chronometer-grade accuracy and has proven to be a rugged and reliable workhorse chronograph movement. It represents an achievement in Chinese watchmaking and has gained popularity among mechanical chronograph enthusiasts for its performance and value.
Automatic mechanical movement beating at 28800 vibrations per hour, with a power reserve up to 39 hours.
This movement is currently the most widely used base movement in Seagull's ST21 series. It delivers the most practical functions a wristwatch requires - hour, minute, second hands and calendar display, meeting daily needs. With 39 hours of extra-long power reserve, the bidirectional rotor winds the movement automatically as the wrist moves, continuously providing robust power for the watch.
Automatic mechanical movement beating at 28800 vibrations per hour, with a power reserve up to 42 hours.
This series is currently the ultra-thin high-end base movement. The movement, the size of a single coin, contains 172 meticulously crafted parts. The movement production line uses fully imported state-of-the-art processing equipment. Each ST18 movement is equipped with an Incabloc shock absorber structure from Switzerland, maximally protecting its ultra-thinness from external shocks.
Automatic mechanical movement beating at 21600 vibrations per hour, with a power reserve up to 45 hours.
The most prominent feature of this movement series is the tourbillon. The wing-shaped tourbillon cage is "suspended" mid-air. Through the tourbillon, the oscillating balance wheel's primitive mechanical rhythm can be observed. The meticulous tiny parts unleash powerful energy, delivering an infinite kinetic aesthetic experience. The beauty of precise mechanical operation is showcased through the panoramic three-dimensional see-through perspective.

Currently, the main focus of this series is on the engraved, skeleton movement. The movement, with a diameter of less than 3cm, relies solely on 16 tiny screws and gears that are barely visible to the naked eye. The rigidity of the machinery and the sensitivity of the openwork combine as one, sculpting light and shadow into a seamless transparency and sensibility in timekeeping.
Automatic mechanical movement beating at 21600 vibrations per hour, with a power reserve up to 39 hours.
This series is currently the classically beautiful "small three-hand" base movement. Movements with a small seconds subdial are called "small three-hand" or "two-and-a-half hand." Evolving from the more primitive pocket watch design, the seconds wheel in the timing train is moved to the bottom so that the hour and minute hands don't have to share the same axis, reducing the space between the gears. This results in the ST17 series of manual-winding movements with an ultra-thin thickness of just 3.2mm.
