Roger Dubuis Excalibur Knights of the Round Table is back—louder, rarer, and more architectural. The new “Enchanter Merlin” chapter transforms Arthurian lore into hyper-horology: 12 pink-gold knights around a sculptural “Table,” a dial that shimmers like a ruthenium-crystal lake, and an RD821 caliber finished to Poinçon de Genève standards and limited to 28 pieces and exclusively available in a boutique.

Why this will go viral (and sell out)
- 28-piece micro-run; boutique exclusive = instant scarcity.
- Debut of “invisibility” diamond setting: hexagonal diamonds clipped into hidden grooves for a seamless, floating top view.
- Fifty-six vertical columns (glass, polished & matte white enamel, rhodium-plated gold, pink gold) set at 0.2–3.7 mm for 3D drama.
- 12 unique 6 mm knights in 18K pink gold, engraved 2–3 days each, viewable laterally via a sapphire ring beneath the bezel.
- RD821 automatic Monobalancier, 4 Hz, 48 h, 14 hand-finishes, 172 components—Poinçon de Genève compliant.

Merlin’s Crystal Palace—on a wrist
As an ode to the palace Merlin conjured to protect the Lady of the Lake, the dial’s base plate (18K pink gold) is precision-drilled into hexagons that host 56 columns: 9 Murano-style glass, 19 polished white enamel, 10 matte white enamel, nine rhodium-plated gold (topped with hexagonal diamonds), and 9 polished 18K pink gold. Beneath it all, crystallized ruthenium delivers a mirror-still “lake.”

The Knights, reimagined
Each knight begins as a paper design, is then transformed into a resin prototype, scanned in 3D, and cast in 18K pink gold. It is hand-engraved with blades, helms, and armor lines, and finished with a black patina for added contrast. The sapphire window below the bezel lets you appreciate the full 360° scene—rare for a non-skeletonized watch.

Certified horology under the theatrics
Inside the 45 mm 18K pink-gold case sits the RD821 automatic movement, featuring a 4 Hz / 28,800 vph, a 48-hour power reserve, 172 components, 33 jewels, and a thickness of 3.5 mm. The movement features 14 distinct hand-finishes to meet the Poinçon de Genève, and a skeletonized 360° rotor evokes medieval stained glass while maintaining efficient winding.

An Inspired Childhood (1938 → 1957)
Born in 1938 in Corsier-sur-Vevey, Switzerland, Roger Dubuis grew up among skilled village craftsmen. Passing the church belltower daily, he recalls: “I used to pass the clock in the belltower of the church. And then, badaboom, I fell in love with that mechanism. That’s how my passion for watchmaking was born.”
Watchmaking proved to be his destiny. A local watchmaker mentored him, and at 15 he joined the École des Arts et Métiers in Geneva, earning his watchmaking diploma in 1957. His student number, 208, was engraved on his tools for life; the “8” later became the Maison’s lucky number, often guiding limited-edition sizes.
For his final coursework, his diploma movement—Calibre 208—was awarded the Poinçon de Genève, setting his bar for excellence from the very beginning.
Becoming an Entrepreneur (1957 → 1990s)
After graduating, Roger joined Longines, repairing chronographs for nine years, then moved to Patek Philippe in the Grand Complications workshop for fifteen years.
Parallel to his positions, he restored antique watches for private collectors, the Musée de l’Horlogerie, and auction pioneer Osvaldo Patrizzi. During the quartz crisis, he co-founded the Groupement Genevois des Cabinotiers (1977) to preserve high watchmaking while staying viable: “I was scared. I thought it was the end of watchmaking.”
Following a health setback and recovery, he joined movement designer Jean-Marc Wiederrecht (M.E → P.M.E), adding his childhood nickname “Placide” to the company name. Their friendship and complementary skills led to the retrograde display patent (1989).
A Maison in His Name (1995 → 2010)
In 1995, at a favorite restaurant, he met entrepreneur Carlos Dias. Their conversation sparked a new Manufacture (SOGEM → Manufacture Roger Dubuis SA), pushing boundaries and bringing their shared vision to life.
Upon leaving P.M.E, he retained half the company assets, including use of the retrograde patent—crucial for the Maison’s first references. The 1996 Hommage chronographs earned Besançon Observatory certification and the Poinçon de Genève. As always, he championed transmission: teaching watchmakers in La Chaux-de-Fonds and educating enthusiasts in horological culture.
He left the Maison in 2003, but in 2007 joined Les Maîtres du Temps: Chapter One (tourbillon, monopusher chronograph, retrograde date/GMT, rolling day and moon bars) with Christophe Claret & Peter Speake; then Chapter Two (2009) with Daniel Roth & Peter Speake (big date, rollers for days and months).
The perfect coda arrived in 2010 when, now part of the Richemont Group, the Maison invited him back as an advisor & brand ambassador, coaching watchmakers and representing the Maison’s soul.
Epilogue & Ethos (2010 → 2017)
Roger Dubuis passed away in 2017, leaving a legacy of expert savoir-faire and the fond memories of those he inspired. His wish endures: “that this philosophy of quality, respect, tradition, and art will remain in the future.”
