Key takeaways
- Stainless steel is highly resistant to rust and tarnish, but not completely immune.
- Salt water, chlorine and sweat left on the steel can cause marks over time.
- Rinse (if water resistant) and dry your watch after the beach or pool.
- Gold-tone and black finishes are coatings: treat them gently.
Stainless steel is the most popular material for watches, and for good reason. But does it rust? Does it tarnish? Here is what you need to know to keep it looking new.

Why stainless steel resists rust
Stainless steel contains chromium, which forms an invisible protective layer on the surface. That layer protects the metal against rust and tarnish and even repairs itself when the surface is lightly scratched. That's why steel watches can be worn every day for years.
What can still affect it
- Salt water and chlorine left to dry on the steel.
- Sweat and dirt building up between the links.
- Harsh chemicals such as bleach and some cleaning products.
These can cause small spots or dullness, usually in hard-to-reach places like the clasp and between the links.
How to prevent marks
- After the beach or pool, rinse a water-resistant watch with fresh water and dry it. Check your rating first: Watch water resistance explained.
- Wipe your watch with a microfibre cloth after a hot day.
- Clean the bracelet regularly: How to clean a stainless steel watch.
Gold-tone and black watches
Gold-tone, rose gold-tone and black watches usually get their colour from a coating on top of the steel. Treat them gently: avoid abrasive polishes and harsh chemicals, and clean them with a soft, damp cloth.

Does stainless steel tarnish?
Not in the way silver jewellery does. If your watch looks dull, it usually just needs a good clean. Small surface scuffs are a different story; see How to remove light scratches from a watch.
Frequently asked questions
Will a stainless steel watch turn my wrist green?
Stainless steel generally doesn't discolour skin. If you notice marks, clean the watch and your skin; sweat and dirt are the usual cause.
Can I wear a stainless steel watch in the shower?
It is best not to, even if the steel itself can handle water. Hot water, steam and soap can affect the seals.
How do I make my steel watch shine again?
Clean it with mild soapy water and a soft brush (if water resistant), dry it well and finish with a microfibre cloth.
