Silence speaks in gold.
Time is not measured. It is crafted.
In an era of disposable seconds, AURUM & CO. stands as a quiet rebellion. Each timepiece is a dialogue between centuries of horological mastery and the uncompromising vision of artisans who refuse to surrender precision to haste. We do not chase time — we give it meaning.
AURUM
Sovereign
The Sovereign embodies the essence of AURUM & CO. — a timepiece where every facet speaks of deliberate mastery. Its emerald sunburst dial captures light like no other, while the in-house Calibre A.187 movement beats with mechanical poetry at 28,800 vibrations per hour.
137 Years of
Unbroken Mastery
The Beginning
In a modest atelier in Geneva, master horologist Heinrich Aurum crafts his first pocket watch — a piece so precise it catches the attention of European nobility.
The Emerald Signature
Second-generation artisan Elias Aurum introduces the iconic emerald dial, sourcing stones from Colombian mines and developing a proprietary sunburst finishing technique.
Calibre A.001
The first fully in-house movement is born. Calibre A.001 achieves chronometric certification with a deviation of just 0.3 seconds per day — a record that stands for two decades.
The Sovereign Collection
AURUM & CO. unveils the Sovereign — a bold reinterpretation of the Maison's heritage. The collection marries 18K gold with emerald dials, establishing the house's modern identity.
A New Chapter
The latest Calibre A.187 movement debuts with 72-hour power reserve and silicon escapement. A commitment to the future, rooted in 137 years of unbroken tradition.
The Art of
Absolute Precision
Every AURUM timepiece is a testament to the relentless pursuit of perfection — where tradition meets innovation in a symphony of mechanical artistry.
Movement Assembly
Each Calibre A.187 movement is assembled by a single master watchmaker over 400 hours. Every component — from the mainspring barrel to the silicon escapement — is finished by hand under 10x magnification.
Dial Finishing
The emerald sunburst dial undergoes 47 individual finishing steps. The proprietary sunburst pattern is achieved through a closely guarded radial brushing technique, followed by multiple lacquer applications and a final galvanic treatment in 18K gold.
Quality Control
Before leaving the Maison, each timepiece endures 1,500 hours of testing across six positions, three temperatures, and simulated decades of wear. Only then does it receive the AURUM hallmark — a promise of perpetual precision.
