Featuring manual winding, it is tailored for mechanical timepieces and is open to customization for various additional functionalities.
At only 5.4mm thick, our fully in-house developed skeleton manual winding movement represents the pursuit of extreme thinness without compromising strength or beauty.
Every bridge, gear, and screw has been meticulously finished by hand. The openwork architecture fully exposes the inner mechanics — the mainspring barrel, gear train, and balance wheel — creating a clean, three-dimensional view of horology in motion.
We deliberately designed this caliber to be slim yet stable. Despite its ultra-thin profile, it maintains excellent running time and delivers the satisfying tactile feel that only a hand-wound movement can offer.
The visible balance wheel oscillates smoothly at the heart of the movement, while the golden and silver-toned components contrast beautifully under light. The result is a highly technical yet elegant skeleton movement that looks impressive through any exhibition caseback.
As a professional watch manufacturing factory, we build this movement from the ground up and offer full customization:
Brand logo engraving on bridges or barrel
Different finishing styles (perlage, Côtes de Genève, polished bevels)
Custom color accents on bridges or wheels
Layout adjustments to match your case design
This 5.4mm in-house skeleton manual movement is ideal for high-end ultra-thin dress watches and serious skeleton timepieces that demand both technical excellence and visual impact.
