THE PROJECT OF Mr J.S.A

BLACK STONE
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.

A WORKSHOP
HUMAN SCALE

Artisans de Genève embodies the fusion between individuals and watchmaking. This is a House where ideas are exchanged and reimagined collaborative way, according to our clients’ aspirations. It is in Geneva that all of the traditional watchmaking professions are brought together in a unique place, offering a multitude of possibilities to meet the diverse needs and desires of each individual client. It is within this dedicated framework that all of the restorations, repairs and modifications that we undertake – at the request of each client – are carried out by hand.

A RETURN TO THE ORIGINS

00 | 00

AN ART DEDICATED
TO OTHERS

Since its inception, our workshop has worked meticulously to offer our passionate clientele the most personalised horology experience. Returning to the origins of the profession where the watchmaker dedicates himself to the individual desires of each client, according to their unique codes, tastes and personal history. It is in this way that we are reconnecting with the roots of a vocation where man, his hands and his tools are definitively bringing the clients’ desires to life.

GUARDIANS OF
MEMORIES

Creativity has been at the heart of our workshop since its inception. Our work almost always consists of bringing together the memories and moments of each individual and transcribing them into the language of watchmaking. Combining different skills and crafts to bring these often intangible moments to life through each person’s project. Combining surprising colours with often forgotten crafts to bring to life, for a moment, old techniques and skills steeped in memories.

FROM PENCIL
TO REALITY

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

CUSTOMIZATION

CREATIVE
WATCHMAKING

Behind each customization lies the desire to stand out, to express oneself and to create a timepiece for oneself. It’s a way of creating a unique piece, according to your choices, tastes and history, by women and men who dedicate their craftsmanship to an entirely personal project.

ARTISAN OF HIS STORY

Artisans de Genève transformed a moment into a unique personalization.

Passionate about wild and extreme sports, this customization is my way of preserving a memory and paying tribute to a force of nature.

Skeleton movment

Skeleton Movement

00 | 00

The soul
of ice

A movement that hides nothing. 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

00 | 00

Absolute black

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

00 | 00

Mysterious
depth

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. The “smoked black” metallization creates a sense of mystery, highlighted by white-gold applied hour-markers. The green Super-LumiNova® evokes nature’s resilience.

OTHER
MODIFICATIONS

Ag Black Stone Mace

Rotor

J.S.A. PERSONAL MARK

BlackStone is a tribute to resilience and the natural elements that shape our world. Black spinel was an obvious choice for its rarity and ethical sourcing, expressing my commitment to the environment. This deep black gemstone symbolises strength and permanence. The sapphire dial reflects the glacier’s duality: both resistant and fragile.
