And 2013 became the year where the powerful product development capabilities accumulated over recent years were fully demonstrated in the new "Excalibur" collection, the most popular among the four series, embodying the "Warrior" image.

At the pinnacle of this is the "Excalibur Quatuor Silicium," which captured the attention of watch aficionados. The combination of an entirely new movement incorporating four balances and, for the first time in watchmaking history, a case made of silicium (silicon alloy), is as visually striking as the booth designed around this new model.

Pursuing Ultimate Timekeeping Accuracy with the "Ensemble" of Four Balances

This highly accurate watch is powered by the ultra-complicated "RD101" movement, composed of 590 parts, incorporating four balances and five differential mechanisms. Developed over seven years, it represents Roger Dubuis' new pinnacle, succeeding the double tourbillon skeleton. The four balances, developed and manufactured in-house, each oscillate at 8 beats per hour (4Hz). Through three differential mechanisms, they synchronize to keep time at an ultra-high beat rate equivalent to 4x8 beats (4x4Hz), achieving superior precision. The remaining two differential mechanisms are integrated within the power reserve indicator at 9 o'clock and the parallel twin barrel system that stores the mainspring's power. The case is made of silicium (silicon alloy), a first in watchmaking history. While extremely lightweight, approximately half that of a titanium case, it offers ample strength and a unique metallic sheen, securely protecting the movement.

Manual winding, silicium case, alligator strap, 48mm case diameter, 30m water resistance, hours and minutes power reserve indicator, new Geneva Seal (pending application), limited to 3 pieces worldwide, 106.26 million yen (estimated price). Release date undecided. A rose gold case model, limited to 88 pieces (estimated price 42.21 million yen / release date undecided), is also available.

Displaying Time with Twelve Heroes Around a Round Table

An art watch inspired by the "Matter of King Arthur," one of the grandest legends and tales of medieval Europe. The dial features a deep, beautiful green and red, achieved through traditional enamelwork known as "Grand Feu," which exhibits a variety of stunning radiance depending on the angle of light. The twelve knights, meticulously sculpted from rose gold, hold their swords towards the center. Through these two artisanal techniques, the world of the legend is recreated on the dial. The design is said to have been influenced by the replica of Arthur's Round Table recreated by King Henry VIII of England (1491-1547) in the Great Hall of Winchester Castle in England. This is undoubtedly a gem for those who cherish this greatest medieval fantasy.

Automatic winding, rose gold case, alligator strap, Grand Feu enamel dial, 45mm case diameter, new Geneva Seal acquired, limited to 28 pieces worldwide, 21.42 million yen (estimated price). Release date undecided. Scheduled for sale at Salon de Roger Dubuis Osaka by oomiya.
