9.4mm Ultra-thin Automatic Tourbillon Watch 42mm
SEA-GULL Masterpiece 2025
Inspired by the aesthetic legacy of China’s Guqin “Jiuxiao Huanpei”, SEA-GULL’s master engineers conquered extreme miniaturization, energy efficiency, dynamic tourbillon display, and precision stability—culminating in a historic ultra-thin automatic tourbillon watch, at just 9.4mm thick.
The Heartbeat Of 9.4mm Ultra-thin Automatic Tourbillon Watch 42mm
Ingenious Structure Of SEA-GULL Movement
Powered by the in-house SEA-GULL ST8610 movement, this tourbillon features 34 jewels, vibrates at 28,800 vph, and delivers a 43-hour power reserve—marking a new milestone in SEA-GULL’s watchmaking excellence.
The ultra-slim profile is achieved through masterful engineering: the movement measures just 4.3mm in thickness, with the rotor refined to a mere 0.8mm. Despite incorporating automatic winding, the caliber remains 20% thinner than traditional manual-winding counterparts.
With a precisely optimized clutch angle and transmission ratio, the automatic winding system ensures efficient, smooth, and stable operation—blending mathematical precision with mechanical artistry in true SEA-GULL fashion.
Aesthetic Visual Refinement on ST8610
Symmetry in motion
The barrel, rotor, and tourbillon are aligned along a central axis—reflecting minimalist Eastern aesthetics.
Exquisite finishing
Multi-layer decoration includes overlapping fish-scale patterns radiating elegantly from the center.
Floating Tourbillon
The Xuanniao (mythical bird)-shaped tourbillon rises 0.5mm above the dial—creating a dramatic yet balanced visual presence.
Cultural Essence - Guqin-Inspired Design Elements
Drawing from the noble symbolism of the guqin—representing refinement and heritage—this ultra-thin automatic tourbillon exquisitely expresses SEA-GULL's quiet luxury and aesthetic variations that are at once timely and timeless.
