In a significant development for the luxury watch industry, Manufacture AMT, the high-end subsidiary of Sellita Holding, has announced two groundbreaking new movement families: the AMT 7000 and AMT 8000. These introductions mark a strategic move to address the growing demand for specialized, high-performance mechanical movements among discerning watch brands. Unlike its parent company, Sellita, which is renowned for its reliable and cost-effective mass-produced movements, AMT focuses on developing bespoke calibres that offer enhanced customization and superior technical specifications. This allows watch manufacturers to incorporate unique designs and advanced functionalities, differentiating their products in a competitive market. The unveiling of these movements, slated for client delivery in early 2027, highlights AMT's commitment to innovation and its role in shaping the future of high-precision horology. The company's unique business model, which involves strict confidentiality agreements and minimum order quantities, ensures exclusivity and maintains the prestigious appeal of its sophisticated mechanisms.

The evolution of Sellita into a dominant force in movement supply and the subsequent establishment of Manufacture AMT reflect a dynamic shift within the Swiss watchmaking landscape. Triggered by significant industry changes, including ETA's reduced supply of ébauches, Sellita, under the leadership of Miguel García, capitalized on the need for alternative, high-quality movement providers. This led to its transformation into a vertically integrated manufacturing powerhouse, capable of producing a wide array of calibres that balance quality with competitive pricing. As brands increasingly sought differentiation beyond standard offerings, AMT emerged to cater to the high-end segment, focusing on movements that integrate advanced mechanical technology and intricate designs. This dual strategy allows the Sellita Holding to serve both the accessible and luxury sectors of the watch market, reinforcing its position as a pivotal supplier in the global horological ecosystem.

The Advanced Capabilities of AMT's New Calibres: The AMT 7000

Manufacture AMT's latest offering, the AMT 7000, represents a new benchmark in automatic movement technology, engineered for exceptional longevity and precision. This calibre boasts a remarkable ten-year service interval, a testament to its robust construction and meticulous design. Measuring 30mm in diameter and 4.60mm in thickness, the movement features 30 jewel bearings, ensuring minimal friction and enhanced operational smoothness. A key innovation is its dual clutch system, specifically designed for manual winding, which disengages the automatic winding mechanism when the watch is hand-wound. This intelligent design not only preserves the integrity and lifespan of the system but also contributes to an impressively smooth winding experience. With a balance wheel inertia of 8 mg·cm², the AMT 7000 is built to achieve chronometer-grade accuracy, making it suitable for COSC certification, all while providing a substantial 84-hour power reserve. Its advanced features and durable construction make it an ideal choice for luxury watch brands seeking a blend of reliability and sophisticated engineering.

The AMT 7000 movement is a self-winding mechanism distinguished by its advanced technical specifications and commitment to enduring performance. Its core features include a precise oscillation rate of 28,800 vibrations per hour (vph) and an impressive 84-hour power reserve, facilitating extended periods of wear without needing to be rewound. The strategic placement of 30 jewel bearings throughout the mechanism significantly reduces wear and tear on critical components, enhancing its overall durability and contributing to the extended service interval. The innovative ball-bearing system further ensures the stability and efficiency of the rotor, optimizing power transfer. Additionally, the incorporation of a stop-second mechanism allows for precise time setting, a crucial feature for chronometric accuracy. Complementing its timekeeping functions, the AMT 7000 also includes a quick-set date display, adding practical utility to its sophisticated mechanical design. These attributes collectively position the AMT 7000 as a highly refined and reliable movement, perfectly suited for the demands of high-end horology.

Exploring the AMT 8000: A Manual-Wound Powerhouse

The AMT 8000 stands out as Manufacture AMT's latest manual-wound calibre, distinguished by its extraordinary ten-day power reserve and sophisticated engineering. This movement, with a diameter of 30mm and a thickness of 6.45mm (or 6.95mm with a power reserve indicator), is also designed for an impressive ten-year service interval, emphasizing durability and reliability. It features either 28 or 38 jewels, depending on specific configurations, along with a single ball bearing for enhanced operational efficiency. A particularly noteworthy aspect of the AMT 8000 is its combination of a high frequency of 4Hz and a substantial balance inertia of 8 mg·cm², an unusual pairing for a movement with such an extended power reserve. This unique configuration ensures consistent rate performance and chronometric precision throughout its long autonomy, setting it apart as a remarkable achievement in manual-wound watchmaking.

At the heart of the AMT 8000's exceptional performance is its innovative four-barrel architecture. This design comprises one large main barrel that directly delivers power to the regulating organ, supported by three additional barrels that continuously rewind and bolster the main barrel. This synchronized system is instrumental in achieving the movement's remarkable ten-day power reserve. By maintaining a constant state of rewind for the main barrel, the AMT 8000 ensures a highly consistent level of torque delivery, which is paramount for stable rate performance and superior chronometric accuracy. Beyond its impressive power management, the AMT 8000 operates at a frequency of 28,800 vibrations per hour (vph) and includes a stop-second mechanism for precise time synchronization. The movement also offers essential functions such as hours, minutes, seconds, and a quick-set date, further enhancing its practical appeal. The sophisticated design and robust construction of the AMT 8000 position it as a pinnacle of manual-wound watchmaking, offering both extended autonomy and uncompromising precision for the most discerning enthusiasts.
