Seagull Qin Ultra-Thin Automatic Tourbillon Watch

The Art of Eastern Slimness

Seagull’s self-developed ST8610 automatic movement is a masterpiece of engineering and philosophy. At just 4.3mm thick—no more than two stacked coins—it embodies the essence of restraint and refinement. Its ultra-thin automatic rotor measures only 0.8mm, 20% slimmer than conventional manual-wind calibers. Every reduction, precise to 0.1mm, reflects a pursuit of balance: subtracting excess to reveal purity. This is not simply a movement; it is an expression of Eastern aesthetics, where elegance is found in subtlety, and “thin” is redefined as strength wrapped in grace.

Precision that Endures

Within its impossibly slim architecture, the ST8610 integrates automatic winding, a high-energy tourbillon, and long-lasting power. Through meticulously recalculated gear curves, energy loss is minimized, allowing microsecond-level accuracy to coexist with endurance. The result: a robust 43-hour power reserve, a stable 28,800 vibrations per hour, and 34 ruby bearings to ensure reliability. It is a harmony of performance and artistry—where durability, accuracy, and innovation unite. This is more than just a watch movement; it is the assurance that your timepiece will keep pace with your life, day after day, with unwavering precision.

Tourbillon without Compromise

At the heart of this creation lies the eccentric tourbillon with a no-regulator design—an innovation that eliminates the friction of traditional balance adjusters. The outcome is revolutionary: timekeeping accuracy and movement longevity increased by 30%. Each rotation of the tourbillon resonates like the pulse of a living heartbeat, transforming the confines of millimeters into a realm of infinite energy. It is both the soul and engine of the watch, unleashing powerful performance in the slimmest possible form, and proving that true strength often hides in subtle spaces.

A Symphony of Light and Craft

Every detail of this timepiece is a canvas of artistry. The front dial radiates with layered fish-scale guilloché, rippling from the center like waves glistening under shifting light—an endless mechanical galaxy in motion. Turn it over, and the Geneva stripes evoke rhythmic order, while the plates shimmer with three-dimensional depth. Seagull’s signature V-shaped rotor embodies symmetry, poise, and balance. Like a guqin resting silently, its strings unplayed yet resonant with harmony, the watch reflects beauty before motion, and rhythm even in stillness. This is craftsmanship elevated to poetry, capturing light, time, and artistry in one.
