From pencil to reality

Black Stone adventure began on paper, with sketches and a multitude of ideas inspired by our customer, which we refined together over time.

The project of Mr. J.S.A.

Time Engraved In Stone

BlackStone is the story of a glacier shaped by time and a man driven by passion for exploration and watchmaking. A glacier made eternal. A story of permanence and resilience.

During his expedition to Alaska, J.S.A. encountered the BlackStone glacier, a symbol of raw beauty in a changing world. Inspired by this adventure, our client entrusted us with his first personalization, seeking to capture both the strength and fragility of that moment.

Focus On Modifications

Mouvement squelette Blackstone

Skeleton movement

The caliber is fully skeletonized, beveled and hand-finished. Its skeletonized yellow-gold rotor and mirror-polished, rounded-off steel balance bridge create a subtle contrast between transparency and depth.

Bezel setting

A bezel where the hand-set black spinels absorb the light, while the sapphire lets it pass through. A stone symbolising both strength and rarity.

Cadran noir Blackstone

Sapphire dial

Carved from a single block of smoky sapphire, the dial symbolizes both the fragility and power of nature. Highly scratch-resistant, the sapphire remains vulnerable to impact, a metaphor for the glacier itself.

Other Modifications

Hands

The white-gold hands are trimmed, beveled and meticulously satin-brushed by hand. To ensure their durability, they are palladium-treated. The seconds hand is sandblasted and features a bright white tip for enhanced readability.

BlackStone is a tribute to resilience and the natural elements that shape our world.This deep black gemstone symbolises strength and permanence. The sapphire dial reflects the glacier’s duality: both resistant and fragile.
