The rise and growth of sustainable materials in watch collections

Historically, the watch is one of the most durable objects designed by man. Conceived to stand the test of time, and even be passed down through generations, it inherently opposes the planned obsolescence that afflicts consumer electronics. However, the watchmaking industry is not exempt from criticism regarding its environmental impact. The extraction of precious metals, the mining of gemstones, the tanning of leathers, and globalised supply chains weigh heavily on a timepiece's carbon footprint.

Today, faced with an increasingly demanding and informed clientele, the sector is undergoing a revolution. The rise of sustainable materials in collections is no longer a simple niche trend or an artificial marketing claim: it has become an essential standard, an industrial necessity firmly rooted in the present. By rethinking the source of its components without ever compromising on quality or aesthetics, modern horology proves that technical innovation can serve environmental ethics.

 

Why must watchmaking rethink its production?

For decades, the prestige of a watch was measured by the rarity and the ecological cost of its materials. Gold extracted using heavy chemicals, alligator leather, or single-use plastics for packaging were commonplace. However, the landscape has changed. Today's watch enthusiasts are no longer merely looking for a beautiful object or mechanical precision; they are seeking a product that aligns with their values.

This paradigm shift profoundly alters the designers' specifications. The pressure is not solely moral; it is also regulatory and economic. Eco-design now intervenes from the very first sketches of a new model. The objective is clear: to drastically reduce the overall carbon footprint of a watch from its manufacture to the end of its life, while guaranteeing the longevity that is the very essence of watchmaking.

This strategic pivot has paved the way for unprecedented research and development. Design bureaus are exploring new chemistries, collaborating with start-ups specialising in recycling, and looking toward other industries (such as aerospace or ethical fashion) to draw viable and robust solutions.

 

The era of circular metals: recycled steel and responsible titanium

At the heart of this transition, the watch case commands the most attention. 316L stainless steel is the absolute standard in quality watchmaking, prized for its corrosion resistance and brilliance. Now, the rise of sustainable materials in collections translates to the massive adoption of recycled steel.

Sourced from carefully sorted and remelted industrial scraps, this new-generation steel presents mechanical and aesthetic characteristics that are strictly identical to virgin steel. The major difference lies in its production, which generates up to 70% fewer CO2 emissions. The recycled alloys are then polished, brushed, or treated with PVD coatings to offer flawless finishes.

Titanium, a material acclaimed for its lightness and hypoallergenic properties, follows the same trajectory. An increasing number of brands are integrating grade 5 titanium from recycling channels, notably by recovering surplus from the medical or aerospace industries. This closed-loop system makes it possible to valorise a raw material that is extremely costly to extract.

Reinvented straps: innovation on the wrist

While the case is evolving, the strap is undoubtedly the most fertile ground for sustainable materials. Traditional calfskin leather, whose tanning requires vast quantities of water and chemicals, is increasingly being replaced or complemented by eco-responsible alternatives.

Among the most striking innovations are:

• Plant-based "leathers": Made from apple residue (Apple Skin), pineapple fibres (Piñatex), or grape pomace. These materials offer astonishing suppleness and visual appeal, all while developing an elegant patina over time.

• Recycled marine plastic: Fishing nets and plastic bottles recovered from the oceans are transformed into robust yarns. They are woven to create NATO-style straps, renowned for their extreme durability and water resistance.

• Natural rubber: Ethically sourced, it replaces petrochemical-derived silicone, offering optimal comfort for sports-oriented watches.

These alternatives are no longer considered "default" choices, but rather premium materials, selected as much for their technical properties as for their low environmental impact.

 

Note: The environmental impacts presented are orders of magnitude derived from life cycle assessments published by various organisations and manufacturers. They may vary depending on manufacturing processes, energy sources, and materials used.

 

Dials and technical components: when recycling becomes design

The creativity of modern watchmaking does not stop at the exterior casing. The rise of sustainable materials in collections infiltrates right beneath the sapphire crystal, redefining the very aesthetics of the dials. Designers now play with the raw textures of recycled materials to create truly unique pieces.

We thus see the emergence of dials crafted from recycled brass, or composites integrating debris from old carbon-fibre racing yachts. The subtle imperfection and asymmetrical reflections of these materials tell a story. The horological object becomes the bearer of a concrete message about circularity.

Furthermore, sustainability is also expressed through the choice of components designed to never wear out. The widespread adoption of sapphire crystal, which is scratch-resistant and unalterable, guarantees that the watch will retain its original clarity for decades. True eco-design consists of manufacturing a product that will never need to be thrown away.

 

Short supply chains and repairability: the importance of local assembly

The origin of materials is crucial, but the way they are transported and assembled is equally important. A watch whose components travel around the world three times before arriving on the wrist loses all its ecological benefit. This is why the rise of sustainable materials in collections is accompanied by a strategic relocation of craftsmanship.

In France, the historic watchmaking hub of Besançon is experiencing a genuine revival. Committed brands, such as Gustave & Cie, are choosing local assembly. Having watches assembled in France not only supports regional employment and expertise but also drastically reduces the carbon footprint associated with final transport.

Finally, sustainability relies on repairability. Using reliable, well-recognised movements for which spare parts are widely available (whether high-quality automatic calibres or quartz movements) assures the owner that their watch can be maintained, repaired, and passed on. A designer watch that is honest about its manufacturing is a watch that refuses obsolescence.

Conclusion

The watchmaking industry is at a decisive turning point in its history. The rise of sustainable materials in watch collections brilliantly demonstrates that tradition and ecological modernity can move forward hand in hand. From recycled steel to plant-fibre straps, and the valorisation of local assembly in France, every detail is now being rethought to minimise the impact on our planet. Purchasing a watch thus becomes a doubly sustainable act: it is an investment in an object designed to measure time throughout a lifetime, while preserving the world in which this time flows. True contemporary luxury is no longer found in destructive opulence, but in responsible elegance and transparency of design.
