Being able to trace the entire life cycle of a material, from its source to its final use, is a major concern for us
Traceability strengthens guarantees related to transparency and the quality of our watches, and limits risks throughout the supply chain, especially during the various processing steps that a product undergoes throughout its life cycle. In recent years, we have enhanced the traceability of our supplies so as to control the commercial channels used to purchase our raw materials. We have also developed a risk attenuation plan to accompany our suppliers in this area.
In addition to national and international regulations, as well as the guidelines established by the International Labour Organization (ILO) and the Organisation for Economic Co-operation and Development (OECD), we adhere to the following environmental certifications and regulations:
Certifications
• London Bullion Market Association (LBMA)
• London Platinum and Palladium Market (LPPM)
• Responsible Minerals Assurance Process (RMAP)
• Responsible Minerals Initiative (RMI)
• Responsible Jewellery Council Chain of Custody (RJC COC)
Environmental regulations
• Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES)
• Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH)
We use two types of precious metal supply: mined gold – extracted from large-scale and artisanal mines – and recycled gold – mainly from our own production waste but also, to a lesser extent, from the watchmaking and electronics sectors.

For our diamond supply, the standards of quality and traceability we demand are such that only 1% of global production meets our requirements, without any compromise on either the volume or the quality of the stones.
Oystersteel is an alloy for which our exclusive suppliers – all based in Europe – use waste from European industry in their manufacturing process. Whilst our ultimate aim is to identify the geographical origin of each of the ores used in the steel alloys supplied by our suppliers, we can confirm at this stage that Russia is not one of our sources of supply.
We follow the principles of the OECD Due Diligence Guidance to ensure the responsible sourcing of tungsten, tantalum and tin.
We plan to roll out a model for platinum similar to that for gold by 2028 and aim to achieve a 95% traceability rate for this material by the same year. Since 2024, we have been implementing an action plan aimed at segregating our waste and excluding sensitive geographical areas from our supply chain.
To date, 72% of our silver supply chains have already been traced. We are continuing our work to gather and verify our sources in order to complete our mapping. By 2028, we aim to achieve 99% traceability for this material.
We source copper for the in-house production of our precious metal alloys. The foundries we work with map their material flows.
We have structured our supply chain for brass – an alloy consisting of copper, zinc and, in very small quantities, tin (less than 0.5%) – in such a way as to minimize the number of intermediaries between smelters and processors.
We source our titanium exclusively from suppliers based in Switzerland who obtain their supplies from American and European smelters. These companies have access to waste from the aviation industry, the circular flows of which are managed and traced.
Mother-of-pearl accounts for more than three-quarters of the total volume of decorative stones used to adorn the dials of our watches. Although there is currently no recognized international standard for this specific market, we are working to trace the origin of this material.
We have been working for several years to identify all the parties involved in our sapphire crystal supply chain. We have mapped our supply chains from the sourcing of alum powder through to the production of crystal, enabling us to select responsible suppliers whilst avoiding high-risk areas.
All suppliers involved in the manufacture of Oysterflex bracelets have signed our Sustainable Development Charter.

The watches we manufacture and sell are mainly fitted with a metal strap, and the number of watches with a leather strap is negligible. In order to trace the origin of this specific material, we have implemented a management tool that enables us to document our supply chain and centralize data relating to our suppliers. Since 2024, traceability has covered not only leather straps but has also been extended to promotional items and watch accessories made of leather.
In recent years, we have extended the traceability procedures originally established for diamonds to cover all coloured gemstones. We are also aiming for 100% declarative traceability for these products by 2026, as well as a triennial assessment of the cutting plants.
