Oris Divers Sixty-Five
Lower PFAS concern, traditional watch materials carry minimal risk.
The Oris Divers Sixty-Five is a mechanical dive watch with a stainless steel case, sapphire crystal, and metal bracelet, materials not typically associated with intentional PFAS use. Oris discloses nothing about PFAS or coatings. No public lab testing or recalls exist.

The full breakdown
What it's made of and why it matters
The Oris Divers Sixty-Five uses a 316L stainless steel case, sapphire crystal, and metal bracelet, materials chosen for corrosion resistance and durability in saltwater environments. Stainless steel does not leach significant heavy metals under normal wear; sapphire crystal is inert and scratch-resistant; metal bracelets avoid polymer-based coatings that could degrade. These are among the safest material choices available for watches.
The brand's record and disclosure
Oris is a Swiss watch manufacturer with no documented product safety recalls or hazardous material controversies in public health databases. The brand does not publish explicit material transparency or chemical disclosures beyond standard marketing. No major certifications specific to chemical safety (e.g., OEKO-TEX, GOTS) are claimed, which is typical for mechanical watches but reflects a gap in proactive disclosure culture.
How it compares in its category
Sports watches in the mechanical/luxury segment typically use stainless steel, sapphire, and metal bracelets, making the Oris Divers Sixty-Five materially representative of its peers. Most competitors in this price and quality tier do not exceed these material standards and face similar disclosure gaps. Watches with plastic cases or rubber straps introduce polymeric off-gassing and durability concerns absent here.
If you buy it
No special precautions are needed beyond standard watch care: rinse with fresh water after saltwater exposure to prevent mineral buildup and corrosion of internal seals. Avoid prolonged exposure to extreme heat (above 60°C) to protect lubricants and gasket integrity. Sapphire crystal will not scratch under normal use but can shatter if subjected to hard impacts; replacement is straightforward through authorized service. Annual or biennial pressure testing and seal replacement is recommended for a dive watch to maintain water resistance.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Metal allergic sensitization (nickel from stainless steel)
316L stainless steel contains nickel as a minor alloying element. Individuals with documented nickel sensitivity may experience localized skin irritation where the bracelet contacts the wrist, though this is not a product defect but a personal incompatibility.
Gasket/seal degradation over time
Water-resistance seals in dive watches use synthetic rubber or elastomer materials that degrade with temperature, UV, and age. No public record of premature seal failure in the Oris Divers Sixty-Five, but periodic replacement (every 5-10 years depending on use) is standard maintenance, not a safety fault.
Case coating or finish degradation
Stainless steel does not require protective coatings and naturally resists corrosion. No reported issues with finish loss, peeling, or metal leaching in the Oris Divers Sixty-Five or comparable 316L watches.
Lead or cadmium in steel or solder
Modern stainless steel watch cases and bracelets are not manufactured with lead or cadmium; lead-free solder standards are industry-wide. No public safety alerts or recalls for this product suggest compliance with these standards.
Off-gassing or VOC emissions
Metal, sapphire, and inert polymeric gaskets do not off-gas volatile organic compounds at any temperature encountered during normal wear or storage.
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.
