Modified Miyota 8215 Movement with Jumping Hour Function

One standout feature of this movement is its remarkable jumping hour function, allowing for quick and accurate time adjustments.

Advanced Calibration: The Overlapping Dual-Disk Jumping Hour Complication

Step into a sector where complex industrial architecture meets high-level watchmaking calibration. This modified Miyota 8215 automatic movement showcases a striking, bare-metal face plate executed with high-density perlage patterning (fish-scale decoration). Consequently, this premium technical surface finish serves as a high-contrast foundation for the proprietary, exposed overlapping wheel train dynamics.

Engineered strictly for long-term operational stability, the caliber replaces standard analog hands with an interconnected, openwork dual-disk regulating system. The upper tracking disc displays instantaneous jumping hour indicators, while the synchronized lower disc rotates smoothly to track mechanical minutes. Furthermore, this heavy-duty engineering structure removes visual clutter, ensuring distinct graphical clarity across the entire watch face.

Technical Infrastructure & OEM Customization
Power Reserve: A robust 42-hour power reserve maintains peak torque and transmission efficiency.

Frequency: Calibrated to oscillate at 21,600 vibrations per hour (vph) for resilient chronological stability.

Jewels: Built with 21 high-grade jewel bearings to drastically minimize component friction and mechanical fatigue.

Beyond underlying mechanics, this high-complication horological platform provides a fully adaptive blueprint for B2B private label customization. The mechanical watch manufacturing facility supports specialized branding integrations, bespoke disk colorways, and custom skeletonized mainplates. Therefore, global watch brands, distributors, and microbrands can seamlessly leverage this reliable, field-tested movement infrastructure to diversify their avant-garde product portfolios.
