Twin Tourbillons, Two Forces in Motion
At the heart of the HS004 is a finely carved double tourbillon movement customized by Shanghai Watch in China. Two tourbillon cages operate as independent visual centers, transforming the regulating mechanism into a dynamic display of mechanical artistry. Operating at 28,800 vibrations per hour with a 40-hour power reserve, the movement combines intricate finishing with the visual drama of twin rotating cages. More than a technical complication, the double tourbillon becomes the defining rhythm of the watch, placing precision, motion, and Chinese mechanical craftsmanship at the center of the design.

Natural Jadeite, A Dial Shaped by Nature
The watch features a genuine natural jadeite dial, selected for its distinctive color and organic character. Unlike manufactured surfaces, natural jadeite carries its own variations in tone, texture, and internal structure, ensuring that every dial possesses an individual visual identity. Framed by the 45mm stainless steel case and contrasted against the intricate double tourbillon movement, the jade creates a dialogue between nature and mechanical precision. Each piece becomes not merely a watch, but a unique composition of stone, metal, and movement.

A 45mm Statement of Horological Art
The 45mm 316L stainless steel case provides a commanding presence while framing the intricate double tourbillon architecture. Its 12.5mm profile balances substantial wrist presence with refined mechanical proportions.

Double-Sided Crocodile Leather
A double-sided crocodile leather strap complements the watch with a refined tactile finish. The folding clasp provides a secure closure while maintaining the collection's luxurious character.

Five Pieces, One Expression
Each dial variant is strictly limited to five pieces. Combined with natural jadeite and a customized double tourbillon movement, every watch becomes a rare expression of Chinese independent watchmaking.
