Digital Product Passport for Watchmaking and Jewellery

High-end watches and jewellery are value assets that change hands many times and require decades of maintenance. MyLime’s DPP replaces the paper warranty booklet with an immutable digital certificate: movement, materials, diamond traceability (Kimberley Process), service history, tracked ownership transfers.

Luxury watch with a MyLime digital certificate and complete movement traceability

Regulatory framework

Voluntary DPP · Kimberley Process, responsible gold

Watchmaking and jewellery are not among the priorities of the 2025–2030 ESPR Working Plan: the DPP is voluntary. What already applies, however, are well-established supply-chain obligations and standards: the Kimberley Process certification scheme for rough diamonds, the EU conflict minerals regulation ((EU) 2017/821) for those importing gold into the EU above certain thresholds, and the LBMA and RJC standards for responsible gold.

Kimberley Process · certified rough diamonds
Regulation (EU) 2017/821 · due diligence on imported gold
LBMA and RJC · responsible gold
Voluntary DPP · immediate competitive advantage

Why act now

A luxury watch is worth its history. Without a verifiable certificate, value decays

The secondary watch market is growing at double-digit rates. Pieces without papers lose 30–40% of their value. The DPP is the digital papers — immutable and accessible in two seconds.

Industry FAQ

Frequently asked questions

Does the DPP replace the paper warranty booklet?

It can: the DPP keeps proof of purchase and the piece’s warranty history in immutable digital form. Many brands still keep the paper booklet as a perceived-value object, pairing it with the DPP.

Can I integrate the GIA diamond certificate?

Yes. The GIA/IGI certificate number is integrated as a structured field and the original PDF is archived. The consumer verifies the reference directly on the lab’s website.

How are vintage or auction pieces handled?

Through Retrofit. The brand or a certified expert issues the DPP starting from photographic and documentary evidence. The piece enters digital traceability from the moment of certification.
