Steel, titanium and ceramic

316L is the stainless steel almost all watch cases are made of — "surgical steel", because it is also used for implants. It does not rust in everyday use, and it releases so little nickel that it complies with EU limits; most people with a nickel allergy tolerate it, but not everyone — a leather or rubber strap is the alternative.

Titanium weighs around 40 % less, is a darker grey and completely nickel-free, but scratches more easily than steel unless it is hardened or coated. Ceramic is practically scratch-proof and keeps its colour forever, but it is brittle and can break from a hard blow. Carbon is light and strong, mostly found in sports watches. The case material is listed in each item's specifications; see, for example, sports watches.
