Credor 50th Anniversary Eichi II Limited Edition

Ever since Credor was born in 1974, each of its creations has showcased the beauty of Japanese aesthetics combined with excellence in watchmaking.
Based on the French crete d’or, or “crest of gold,” the Credor name has always suggested the highest echelon of artistry in watchmaking.
The year 2024 marks Credor's 50th anniversary, and a special edition of the acclaimed Eichi II will mark the occasion.

A beautiful porcelain dial made with a special technique

The commemorative watch features a deep blue porcelain dial whose color is referred to as
ruri, after the Japanese word for lapis lazuli. The dial has a gentle curve thanks to the careful application of porcelain glaze, which creates surface tension and gives it a slightly domed shape. The porcelain glaze also creates an effect that enables wearers to enjoy the dial’s varying colors depending on the angle of view and the brightness of the surroundings.
The hour markers, the Credor logo at the twelve o'clock position, and the Credor letters are all hand-painted by a craftsman at the Micro Artist Studio, the elite watchmaking workshop where the watch is crafted. After the dials are fired, gold is applied over the paint to create a warm, multi-dimensional beauty that only hand-craftsmanship of the highest order can achieve. The technique is a nod to ‘Ruri-Kinsai,’ a famous yet rare form of traditional craftwork that came to widespread attention during the Edo period, in which gold is overglazed on ruri-colored material, such as porcelain. The arduous and highly technical application of gold on the ruri-colored dial combined with the 18K yellow-gold case creates a unique beauty befitting a watch made to celebrate Credor’s 50th anniversary.

The innovative Torque Return System for an extended power reserve

When the mainspring has been fully wound and the torque output is at its highest, approximately 30% of the available power is not needed to maintain the precision of the watch and is in effect wasted in a normal movement. The Torque Return System uses this energy to rewind the mainspring, increasing the power reserve. In Caliber 7R14, this system is active for 35 hours after the mainspring has been fully wound.
By using the available energy more effectively, the Torque Return System increases the power reserve of the Caliber 7R14 to around 60 hours. This represents a 25% improvement over the manual-winding Spring Drive Caliber 7R88, which delivers 48 hours of power reserve.

Beautiful finishing with a Japanese aesthetic

The edges of the movement’s bridges and the holes for the screws and jewels are convex and polished by hand by skilled artisans to catch light from any angle.
