The most complex single piece of sapphire in watchmaking - a sapphire skull with more edges and facets than a brilliant-cut diamond - is suspended over our first Swiss-made open work tourbillon: the GT-01S.
Our story begins logically - with a question: why do most skull watches on the market sacrifice their design to the limitations of their movement and case?
It's as if the makers decided to add a skull to an existing movement base and case- creating their art within limitations. The skull becomes a compromise. Holes are cut in the head, or its mouth is disconnected - they restrict the expression of their art due to the limitations set by their approach.
We wanted to make a timepiece built entirely around the skull - a single piece skull with depth and character that defined its movement and case.

Invisibly suspended over our first Swiss-made openwork tourbillon is an industry-first, cementing Aventi as masters of Sapphire - the Sapphire Skull. It takes over 500 hours to produce a single skull and one mistake, smaller than a human hair, is enough to shatter everything. We spoke with master gem cutters worldwide and they all said it wasn’t possible; we proved them wrong.
To put it in perspective, a brilliant-cut diamond is considered one of the most complex diamonds to cut. It has 58 facets. Our skull has 160 facets and is as thick as a grain of rice. As there were no gem cutters that could cut what we wanted from a single piece of Sapphire - we took action ourselves. We used our experience in CNC machining Sapphire, hand polishing, and watchmaking to do something they thought impossible. After more than one year of trial and failure, we proved the gem cutters wrong. As a result, it is the most stunning Sapphire Skull in the watch industry.
Our openwork tourbillon is built on the shoulders of giants. A tourbillon more efficient and robust than ever before. We didn’t build this movement alone; we partnered with pillars of accuracy and watchmaking with centuries of experience. Masters in the heart of Switzerland crafted every component of this engine. Our partners include companies such as; Atokolpa, Generale Ressorts and TEC Ebauches, the same companies who have worked with Audemars Piguet, Richard Mille and now Aventi.

63 components are mounted in the grade 5 titanium main plate compared to a traditional tourbillon with more than 300 possible points of failure. Finished to a level in line with the best and guaranteed perfection through a quality control process like nothing our partners had seen before. Every edge bevelled and polished, every facet covered in intricate perlage, protected by a medical-grade black carbon coating.

Most hands are made from processed metals but rarely gems. We developed our sapphire hands to match the skull centrepiece's complexity and brilliance. Every facet and edge is hand polished to perfection - with a thickness of 0.3mm. No traditional hand makers can produce these hands, only masters of Sapphire.
