Tudor Pelagos Men's Titanium Watch with Black Rubber Strap

F · High PFAS

Lower PFAS concern; titanium and rubber are inherently low-risk, but rubber strap waterproofing method undisclosed.

The Pelagos uses titanium (inherently PFAS-free) and natural rubber, both lower-concern materials. However, Tudor does not publicly disclose whether water-resistance seals or the rubber strap use water-repellent coating/Teflon-family coating treatments, a common PFAS source in watches.

What we don’t know

This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.

No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.

The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.

Formulations and coatings change between production runs. Always check the current label before buying.
