Ultra-Thin Skeleton Movement

WatchesHome In-House Ultra-Thin Skeleton Movement – 5.4mm Openwork Mastery

At just 5.4mm thin, our fully in-house developed skeleton automatic movement stands as a testament to precision engineering and refined design.
We deliberately placed the balance wheel at the 12 o’clock position, creating a visually balanced and harmonious openwork architecture. Every bridge, gear, and ruby jewel is meticulously finished by hand, with brushed surfaces and polished bevels that catch light beautifully through the skeletonized structure.

Despite its ultra-slim profile, the movement maintains excellent stability and performance. It runs at 28,800 vph for smooth sweeping seconds, offers a solid power reserve, and delivers reliable daily accuracy. The open design not only showcases the beauty of the mechanics but also reduces overall weight while preserving structural integrity.

As a professional watch manufacturing factory, we build this movement from the ground up. We offer full OEM customization including rotor engraving, brand logo integration, different finishing styles, and small functional adjustments — all with strict quality control and consistent production standards.

This in-house ultra-thin skeleton caliber is ideal for elegant dress watches and high-end skeleton designs that demand both exceptional thinness and visible mechanical artistry.
