In-Depth: Orient Star’s Silicon Escape Wheel
Orient Star has introduced a silicon escape wheel that marks a significant advancement in the Japanese watch industry, where adoption of silicon components has been slow due to patent restrictions and durability concerns. This innovative wheel, which is approximately 65% lighter than traditional nickel-silver options and features an 80% reduction in drop distance, enhances energy efficiency by allowing around 30% more energy to reach the balance. The manufacturing process leverages advanced semiconductor techniques, resulting in durable, precise components that promise improved performance and longer power reserves for mechanical movements. The production of the silicon escape wheels takes place in Seiko Epson's Fujimi plant, utilizing a method that ensures high precision through photolithography and etching. Once crafted, the escape wheels are designed to be mounted without adhesives, employing flexible arms to secure them in place. This innovative approach is part of a broader effort by Seiko Epson to commercialize silicon technology in accessible timepieces through its Orient Star brand, exemplified by models like the M34 F8 Skeleton, which showcases this cutting-edge technology at a reasonable price.
