Fossil Women's ES5245 Stainless Steel Analog Ring Watch
Stainless steel watch, lower concern. No waterproofing treatment disclosed.
Fossil's stainless steel ring watch contains no known PFAS-prone coatings based on typical watch construction. Stainless steel itself is inherently PFAS-free; no water-resistant or nonstick treatments are standard in dress watches.

The full breakdown
What it's made of and why it matters
The ES5245 case is stainless steel (typically 316L or 304), which is chemically inert and does not leach metals under normal skin-contact conditions. The crystal is described as mineral or hardened glass, both of which are stable and do not off-gas or degrade from body heat or moisture exposure. Fossil has not disclosed any decorative coatings, nickel plating, or water-resistant treatments on this model, which eliminates several potential chemical hazard pathways common in fashion watches.
The brand's record and disclosure
Fossil Group does not publish detailed material safety data sheets or PFAS declarations for consumer watches. The brand has faced no documented product safety recalls specific to chemical leaching in watches, though broader fashion-watch litigation exists in the industry around heavy metals and allergens. Fossil's silence on PFAS and coating chemistry is typical for the fashion-watch segment; the company prioritizes design over transparency.
How it compares in its category
Fashion analog watches with stainless steel cases and mineral glass are among the safest options in the accessory category, because they avoid polymer coatings and waterproofing resins where PFAS or phthalates concentrate. Compared to fashion watches with colored metal plating, resin cases, or synthetic leather straps, this model eliminates several chemical-contact pathways. The ring bezel design (if decorative metal) poses negligible risk versus painted or enameled dials.
If you buy it
Remove the watch during showering or prolonged wet exposure if water resistance is not rated, to avoid moisture accumulation under the caseback. Clean the case and band monthly with a soft damp cloth to prevent salt or skin-care product buildup. If the crystal becomes scratched or cloudy, replacement is safe and straightforward. Check the band attachment points annually; if the band is leather or fabric, replace it if it shows signs of deterioration or odor from moisture retention.
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.”
Nickel leaching (skin contact)
Stainless steel watches can release trace nickel over extended skin contact, especially in individuals with nickel sensitivity. Fossil does not disclose the nickel content or any barrier coating; 304 stainless can contain up to 10% nickel, whereas hypoallergenic alternatives use 316L or titanium.
Mineral glass crystal degradation
Mineral and hardened glass crystals do not off-gas or leach under normal use. However, scratching and cloudiness over time are cosmetic issues that do not pose chemical hazards.
Watch band material hazards (material-dependent)
If the band is leather, vegetable tanning or chrome tanning can introduce formaldehyde and heavy metals; if fabric, azo dyes are possible. Fossil does not specify band tanning or dye methods for the ES5245 stainless steel variant. This model's band material is not disclosed in the product context; if it is stainless steel, risk is minimal.
Moisture and bacterial growth under caseback
Without a stated water-resistance rating, prolonged moisture under the caseback can promote corrosion of internal components and bacterial biofilm growth. This is a hygiene and durability issue rather than a chemical leaching hazard, but moisture trapped against skin creates an environment for secondary mold or microbial growth.
Heavy metal pigments in dial or indices
Fossil does not disclose ink or pigment formulations for watch dials. Cadmium or lead in dial inks are rare in modern fashion watches but remain unconfirmed for this model. No recalls or adverse reports are on record for this specific model.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 82% 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.
