Small Seconds, Leap-Year display
Since 2005, the first "calendar and astronomy" complication developed by Chopard Manufacture and named L.U.C Lunar One has featured a self-winding mechanical movement with a perpetual calendar as well as a precision orbital moon-phase display. This moon-phase mechanism is exceptionally accurate, deviating by just one day every 122 years. L.U.C Calibre 96.13-L now powers a newly redesigned timepiece, whose profile has been reshaped in line with the latest L.U.C aesthetic.
Crafted in 18-carat ethical white gold, the case features a bassine shape, meaning its base is narrower than its domed, polished bezel. Reflecting craftsmanship inspired by the pocket watches that emerged from Louis-Ulysse Chopard’s creative heritage in the 19th century, this distinctive profile creates an impressive sense of visual sophistication. This new case with its vertical satin-brushed sides is paired with a curved, fluted crown that is not only elegant but also easy to handle. The slightly domed sapphire crystal perfectly matches the curves of the bezel, giving the watch a rounded, harmonious profile. Further demonstrating the fine craftsmanship of this timepiece, the lugs are made separately before being welded to the case to ensure a perfect aesthetic result. The dial, meticulously hand-guilloché using traditional artisanal techniques, ensures optimal legibility of its indications. Additionally, an ingenious interchangeable strap system offers wearers a variety of options.
While the movement’s accuracy is chronometer-certified, the exceptional quality of this L.U.C Lunar One model’s finishing has also earned it the prestigious Poinçon de Genève quality hallmark.
For many years, Chopard has taken concrete action to help shape a more responsible luxury industry, fully aware of its environmental impact and its responsibility toward the thousands of individuals involved in its activities worldwide. As an early member of key industry organizations such as the Responsible Jewellery Council (RJC), the Maison has distinguished itself through its pioneering commitment to ethical gold and the development of Lucent Steel™, consistently adopting a proactive stance within the sector.
Gold, a fundamental material in Chopard’s production, has naturally become a central focus in the Maison’s Journey to Sustainable Luxury. In July 2018, Chopard reached a major milestone by exclusively using ethical gold in its workshops, meeting the most stringent international environmental and social standards. Within this approach, gold has been sourced through two transparent and traceable channels: responsibly produced artisanal gold and recycled gold certified by the RJC. The RJC’s Chain of Custody (CoC) standard defines the requirements for identifying and tracking eligible materials, including certified recycled gold from legitimate sources.
In 2024, Chopard’s ethical gold was sourced solely from artisanal and small-scale mines accredited by the Swiss Better Gold initiative. Responsible sourcing of artisanal gold is essential to Chopard’s strategy, as it enables full traceability from mine to finished product while generating positive and tangible socio-economic and environmental impact. Artisanal and small-scale mining involves millions of men and women around the world—individuals working alone, with their families, or in cooperatives—using basic exploration and extraction methods. Since 2017, this program has supported lower-impact extraction methods and improved the living and working conditions of over 5,000 miners and gold panners in Peru and Colombia. The Maison does not source from large-scale industrial mines.
A key objective is to continue generating positive impact within artisanal and small-scale mining communities by helping address local challenges related to water access, education, and energy. To achieve this, the Maison works closely with international organizations such as Swiss Better Gold Association, which are committed to helping gold miners adopt more socially and environmentally responsible practices. The premium paid by Chopard provides additional support for energy transition, infrastructure development, and the creation of alternative economic opportunities alongside mining activities.
Since 1978, Chopard has been one of the few watch and jewellery manufacturers to operate its own foundry. This independent approach allows the Maison not only to guarantee the origin of the gold used in its workshops but also to remelt production scraps in-house. This direct reprocessing ensures traceability of alloys, avoids electrochemical refining, reduces energy consumption, and eliminates the use of chemicals. It also significantly cuts emissions linked to material transport.
