At the center of this movement is a striking dual-color rotating day-night sphere—deep lapis blue paired with luminous gold—offering a poetic representation of time’s natural rhythm
The 6T15 Skeleton Movement is our upgraded in-house automatic caliber that balances strong performance with clear visual appeal.
Its most distinctive feature is the dual-color day-night rotating sphere — made of deep blue lapis lazuli on one side and brass on the other. As it turns, it clearly shows day or night at a glance, adding both function and a subtle celestial touch to the dial.
The movement features a full skeleton layout, so the gears, bridges, and jewels are fully visible. Every component is carefully finished to show the clean mechanics and precise assembly. We also reinforce the structure to ensure long-term stability and reliable accuracy.
Designed for modern skeleton watches, the 6T15 works well for both dress and contemporary styles. It offers a good combination of technical reliability and attractive openwork design at a competitive level.
As a professional watch manufacturing factory, we provide full OEM customization:
Day-night module adjustments
Different skeleton layouts and bridge designs
Brand logo engraving
Additional complications or functional upgrades
We handle everything with strict quality control and efficient production.
This movement is a practical choice for brands that want a reliable skeleton automatic with a unique day-night feature and strong customization possibilities.
