YS Factory

YS Factory was established during a period of rapid structural advancement in the mechanical replica watch industry. In its early stages, the factory focused on movement modification and complex function adjustment, gradually building a reputation among collectors for its technical capabilities. Unlike factories that primarily emphasize exterior replication, YS has consistently prioritized movement architecture and long-term mechanical stability—especially in the development of tourbillon structures.

The tourbillon was originally invented by Abraham-Louis Breguet, designed to counteract the effects of gravity by placing the escapement and balance wheel inside a rotating cage that averages positional errors. Building on this foundation, YS Factory focused on improving cage stability and rotational smoothness, reinforcing bearing support systems and optimizing balance wheel calibration to enhance overall performance and durability.

Over time, YS developed a product philosophy centered on “structure first, complexity focused,” with particular attention to single-axis and flying tourbillon models. While not positioned as a high-volume manufacturer, the factory gained recognition for its stable adjustment standards and continuous technical refinement. Within the replica tourbillon segment, YS Factory has established a niche identity appealing to collectors who value mechanical sophistication and structural precision.
