Creative Watchmaking

A workshop human scale
Artisans de Genève embodies the fusion between individuals and watchmaking. This is a House where ideas are reimagined collaborative way, according to our clients’ aspirations.

An art dedicated to others
Since its inception, our workshop has worked meticulously to offer our passionate clientele the most personalised horology experience.

Guardians of memories
Creativity has been at the heart of our workshop. Our work almost always consists of bringing together the memories of each individual and transcribing them into the language of watchmaking.

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.
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.


Sourcing Of Materials And Colors
Every material and hue is carefully selected to embody both elegance and durability, resulting in a timeless and truly personalized timepiece.

Absolute black bezel
Black spinel was an obvious choice for its rarity and ethical sourcing.

Mysterious depth
The “smoked black” metallization creates a sense of mystery, highlighted by white-gold applied hour-markers.

Super-LumiNova®
The green Super-LumiNova® evokes nature’s resilience.

The soul of ice
A movement that hides nothing.

Focus On Modifications

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.

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

Rotor

Balance bridge
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.
