Product Description
A 70-hour power reserve is achieved with a silicon escape wheel. The movement, consisting of over a hundred precision parts, is hand-assembled by specialized craftsmen in Akita, embodying exceptional skill and dedication.

This masterpiece combines a classical design with an innovative movement utilizing cutting-edge technology.
The newly adopted silicon escape wheel, which boasts improved lightweight properties and processing accuracy, enhances the energy transfer efficiency of the escapement, enabling a 70-hour power reserve. The self-developed silicon escape wheel, utilizing MEMS processing technology also used in Epson's high-definition print head manufacturing, features an innovative original structure with spring properties. Furthermore, leveraging Epson's semiconductor technology, the silicon escape wheel achieves a vibrant blue by adjusting light reflectivity with nanometer-level film thickness control.
