The Excalibur Brocéliande Twilight Blue captures the instant when day loosens its hold on the forest. In Brocéliande, twilight does not simply arrive; it gathers slowly, deepening the canopy to a saturated blue as the last threads of light slip between the branches. The watch is shaped around that suspended moment, when the forest seems to pause before night claims it. White mother‑of‑pearl leaves shimmer against a dial coated in midnight lacquer, while two sapphire discs drift freely across its surface like fragments of moonlight. Beneath this living tableau, a newly developed skeletonized caliber—bearing the Poinçon de Genève—beats with quiet precision, its architecture visible through the transparent caseback.

The 38 mm case, crafted in 18K pink gold, frames the dial like an entrance into the deep woods. Its three‑lug silhouette and fluted bezel anchor the design in the Excalibur lineage, while the open caseback reveals the movement in full. The watch is water‑resistant to 3 bar, a subtle reminder that its purpose is not to conquer the elements but to celebrate them.

The dial itself is conceived as a scene rather than a surface. A sapphire‑glass base, lacquered in a deep twilight blue, serves as the backdrop for rose‑gold branches that stretch across it. Each mother‑of‑pearl leaf is individually selected, engraved, and polished by hand, its white surface catching the surrounding blue in a slightly different way from its neighbors. Gold‑plated hour markers glow with multicolor Super‑LumiNova, guiding the eye without disturbing the composition. Two rotating sapphire discs positioned at two and seven o’clock carry their own clusters of leaves, drifting slowly as the watch moves. Even the micro‑rotor is part of the forest, adorned with a sapphire disc and delicate branches that echo the dial above.

The strap, crafted from deep blue alligator leather, completes the chromatic descent from sky to canopy. Its tone mirrors the dial’s lacquer, creating a seamless transition from wrist to watch.

Since 2015, the Maison has returned to the Arthurian forest of Brocéliande as a source of inspiration. This is the land where Viviane is said to have lived beneath the lake and where Merlin met his fate, bound by his own enchantments. Each new creation explores a different facet of this mythical landscape. The Twilight Blue chapter ventures into the threshold between day and night, where the forest becomes a place of silhouettes, whispers, and shifting light.

The dial is a testament to Métiers d’Art craftsmanship. Every leaf, every branch, every lacquered surface has passed through the hands of artisans who work at the intersection of high jewelry and haute horlogerie. The sapphire dial is not merely a transparent layer but an integral part of the design, coated in midnight blue and finished to the same standard as the gold and mother‑of‑pearl above it. The Poinçon de Genève marks the culmination of this meticulous work.

At the heart of the watch lies the RD721SQ, an automatic skeletonized movement created specifically for this piece. It beats at 4 Hz, offering a 72‑hour power reserve through an openworked barrel. A tungsten‑and‑gold micro‑rotor is integrated seamlessly into the skeletonized structure, allowing the movement to remain airy and transparent. Through the sapphire caseback, the fully open bridge architecture becomes part of the visual experience, turning the mechanics into an extension of the forest narrative.
