The 10th anniversary of Credor Spring Drive Eichi is celebrated in rose gold

The original Eichi, created in 2008, and its successor Eichi II, 2014, won high praise worldwide for their simplicity of design, the exquisite finishing of the movements, the innovative torque return system and, most of all, for the hand-painted, pure white porcelain dials.

Today, ten years after Eichi first appeared, a new version of Eichi II brings all these attributes together in a new 18k rose gold interpretation. It will be available in August at selected Seiko Boutiques and retail partners worldwide.

A cold forged gold case and Zaratsu polishing

The rose gold case has a precision and brilliance that could only be achieved by combining a cold forging process with meticulous hand polishing. Thanks to the greater density created by the cold forging of the gold, every surface shines with particular brilliance and the case is more resistant to scratches. The elegantly curved surfaces are Zaratsu polished, a task that requires a consummate skill which is fully rewarded in the sharpness of every surface and the complete absence of any distortion.

Eichi II, a hand-made masterpiece

Eichi means wisdom in Japanese. The name reflects the fusion of traditional Japanese watchmaking skills with the highest and most advanced Spring Drive technology. From the design of every component to the hand painting of the dial, Eichi II is made by elite watchmakers at the Micro Artist Studio in Shiojiri in central Japan. Founded in 2000, this studio has developed a worldwide reputation with masterpieces like the Credor Spring Drive Sonnerie (2006), the Credor Spring Drive Minute Repeater (2011), Credor Spring Drive Eichi II in 2014 and the Grand Seiko Spring Drive 8 Day Power Reserve (2016).

Spring Drive and the Torque Return System

Eichi II is not only a masterpiece of watch craftsmanship, it also delivers truly remarkable performance. Unique among spring-powered watches, Spring Drive offers a precision of one second a day. The Torque Return System is a proprietary mechanism that maximizes the advantages of the Spring Drive movement’s high torque. After the mainspring has been fully wound, the torque output is at its highest and approximately 30% of the available power is not needed to maintain the precision of the watch and is effectively wasted in a normal movement. However, the patented Torque Return System uses this energy to rewind the mainspring, resulting in a 25% increase in the power reserve, which is a remarkable 60 hours.
