The unique grade 5 titanium base plate are machined in partnership with TEC Ebauches. One of the leading names in high tolerance and complex machining, working with brands as Purnell and other complicated tourbillon movements.The First step in the assembly of the movement is the baseplate. Milled from grade 5 Titanium, this is the foundation for the rest of the watches components to be built within. Each baseplate is milled from grade 5 titanium to match the exact shape of the Aventi case. The baseplate determines the placement of every component in the watch. Using 3D modelling, the exact placement of the recess and holes for every component is mapped out and cut into the base plate within a minute tolerance. Once completed, the watchmaker can begin removing any titanium not absolutely necessary. Thus, removing excess weight from the movement and allowing a better view of all the movements components.

Our workhorse movementgenerations
We wanted to create one of the highest quality movements, one that’s accurate, reliable and finished to an incredible level— focusing not only on the final result but also the most efficient, reliable and robust way to achieve it—a grand complication for everyday wear.

We didn’t build this movement; we worked with a team of the greatest talents in the world. Pillars of accuracy and watchmaking, with centuries of experience. Masters in the heart of Switzerland crafted every omponent of this engine. Companies including Atokolpa, TEC Ebauches and Generale Ressorts, the same companies who have worked with Audemars Piguet, Richard Mille and now Aventi.

Swiss made
All of these components are brought together in La Chaux-de-Fonds, Switzerland, a city of great importance in watchmaking. 150km north of Geneva, La Chaux de fonds is where Swiss watchmaking became the gold standard. Some of the finest watches in the world were designed and produced here; Gerrad-Perregaux, Greubel Forsey, Omega, Rolex’s first Swiss operation and now Aventi.
Our movement is made in partnership with Olivier Mory - our master watchmaker who worked with AP concept on the Richard Mille RM001.Crafted in solid grade 5 titanium. Each edge is bevelled and polished, every facet finished with perlage. Protected by a medical-grade carbon black coating, decorated with deep gold engraving. Our workhorse movement, built on the shoulders of giants.

Once Each movement has been assembled, it is individually inspected and the rate adjusted by master watchmaker Olivier Mory. This adjustment is the process Olivier has stated he finds both the most difficult and the most enjoyable.
The rate adjustment process is critical to the accuracy of the movement by making precise adjustments to the balance spring within the Tourbillon cage. These adjustments are made to ensure exactly six oscillations of the balance wheel occurs per second. If the Balance wheel is oscillating too slowly, the spring is pulled shorter, too fast, and length can be added to the balance spring. The rate adjustment process is a time consuming and intricate process, taking years of training and experience to be done effectively and efficiently.

Once the movement has been adjusted, and the accuracy checked, the movement will go through a final inspection to ensure nothing less than perfection. The movement is now ready to be mounted within the case, Breathing life into the Aventi A13.
The GT-01S, a 100% Swiss Hand-wound tourbillon is a movement like no other. Designed with reliability, efficiency and longevity while pushing the limits of movement finishing. Watch movements aren't the product of just one person or a single brand. A team of some of the greatest talents in the world creates them. We worked with the same talents that are responsible for the movements of Richard Mille, Audemars Piguet, Piaget, Panerai, and IWC and now Aventi.
