Ultra-thin Automatic Tourbillon: A New Chapter in Precision Watchmaking

A New Era of Tourbillon Watches

Tourbillon watches have long represented the pinnacle of mechanical artistry. The Ultra-thin Automatic Tourbillon from Sea-Gull Watch marks a new direction in high-end horology, combining advanced engineering with refined aesthetics. Designed for those who value both performance and cultural resonance, this timepiece stands as a bridge between tradition and forward-looking innovation.

The Innovation Behind the ST8610 Movement

At the heart of the Ultra-thin Automatic Tourbillon is the new ST8610 caliber. With a movement thickness of only 4.3mm, it represents a significant leap forward in the pursuit of ultra-thin tourbillon watches. The automatic rotor, a mere 0.8mm thick, integrates seamlessly without adding bulk, achieving an overall thickness just 80% of a traditional hand-wound tourbillon movement.

Despite the compact form, the performance is uncompromised. The energy system simultaneously supports automatic winding, a high-consumption tourbillon, and extended power reserve. The result is 43 hours of reliable autonomy in a slim construction.

The ST8610 elevates mechanical stability through a vibrational frequency of 28,800 vph, ensuring precise timekeeping. An upgraded gear profile reduces transmission loss, while the adoption of a no-index eccentric tourbillon eliminates the friction issues common in traditional regulators. This innovation improves accuracy and extends service life by approximately 30%, offering a balance of technical mastery and lasting reliability.

An Ultra-thin Design Inspired by Oriental Aesthetics

The Ultra-thin Automatic Tourbillon demonstrates that beauty can coexist with complexity. Three essential components—the mainspring barrel, rotor, and tourbillon—align in a straight line, forming a minimal yet harmonious industrial design. This symmetry reflects the restraint and balance of Eastern aesthetics, achieving both mechanical integrity and visual harmony.

The rotor design echoes the abstract form of the Sea-Gull logo, revealed subtly as it swings, while the floating tourbillon sits just 0.5mm above the dial, achieving perfect visual proportion. It avoids appearing sunken or excessively raised, striking the ideal balance for aesthetic refinement.

Craftsmanship in Every Detail

Beyond mechanical innovation, this Sea-Gull tourbillon celebrates the artistry of fine finishing:

• Fish-scale patterning radiates from the center of the front plate, producing depth and visual rhythm.
• Geneva stripes on the reverse side enhance dimensionality with alternating light and shadow.
• A double concentric Geneva finish on the mainspring barrel adds layered sophistication.

The dial design pays homage to the Chinese guqin, a traditional string instrument. Its cracked lacquer-like texture, recreated through intricate micro-engraving, reflects the “thousand-year crackle” aesthetic of lacquerware. Applied indices mirror the guqin’s curved form, while polished and brushed finishes mimic the interplay of strings. Fine brushing on the central axis simulates string tension, while polished dauphine-style hands shift dynamically with changing light.

Completing the composition, the timepiece is fitted with a hand-stitched crocodile leather strap, selected for its durability and rich, natural texture.

The strap is secured with a horseshoe-shaped buckle, a design inspired by the curved armrests of Tang Dynasty official’s chairs. These chairs, known for their dignified silhouette and symbolic association with authority and order, lend a subtle layer of cultural resonance to the watch. The buckle’s smooth arc echoes the graceful lines of these ancient seats, transforming a functional detail into an elegant tribute to Chinese heritage. The interplay between the organic leather grain and the polished metal buckle highlights the harmony of craftsmanship, functionality, and symbolism, allowing the watch to embody both modern sophistication and a discreet historical narrative.

The Ultra-thin Benchmark

In the competitive landscape of tourbillon watches, thickness and performance define true mastery. While other ultra-thin models range between 9.6mm to 11.65mm in case thickness and retail for $60,000 to $180,000, the Sea-Gull Ultra-thin Automatic Tourbillon offers a remarkable alternative.

With a 9.4mm profile, high-frequency stability, and an extended power reserve, this model delivers exceptional value at $4,199.

As a bonus, every purchase includes a complimentary white replacement strap, allowing you to switch seamlessly between business and casual styles. This balance of affordability, refined craftsmanship, and added value makes it not only a perfect entry into haute horlogerie but also a confident statement of independent innovation.

The Ultra-thin Automatic Tourbillon is more than a technical achievement—it is a symbol of contemporary watchmaking rooted in heritage and precision. For discerning collectors and professionals seeking mechanical depth and cultural sophistication, it represents an invitation to explore a new era of Sea-Gull tourbillon innovation.
