Steel, titanium, gold and coatings: case materials compared
Compare the four common case materials on weight, wear and skin comfort, so you can pick the one that suits how you wear a watch.
Stainless steel is the sensible default: tough, easy to refinish and unaffected by sweat. Choose titanium for a lighter watch, solid gold for its colour and metal rather than toughness, and treat a gold-tone or PVD finish as a thin coloured layer that can wear through at the edges.
At a glance
| Material | Weight | Scratches | Skin | Refinishing |
|---|---|---|---|---|
| Stainless steel | Medium | Resists well, marks with wear | Contains some nickel | Easily brushed or polished at a service |
| Titanium | Light | Scuffs more readily unless treated | Nickel-free itself | Possible, but harder to polish than steel |
| 18k gold | Heavy | Soft, collects fine marks | Rarely a problem; ask about white gold | Polishable, but each polish removes metal |
| Gold-tone or PVD coating | As the base metal | Hard-wearing until it wears through | As the base metal | Cannot be polished back; needs re-coating |
Steel
Steel is the most common case material at almost every price. It resists corrosion from sweat and seawater, takes a sharp polish, and a watchmaker can remove light scratches at a service. Brands use different grades; Rolex, for one, uses a 904L steel it calls Oystersteel. Watch steels contain some nickel, so if you have a nickel allergy, look at titanium.
Titanium
Titanium is over 40 percent less dense than steel, so a titanium case and bracelet feel noticeably lighter, though the movement and crystal weigh the same either way. Titanium itself contains no nickel, but the clasp or caseback may be a different metal, so check if you have an allergy. Untreated titanium, especially the pure grade, scuffs more readily than steel, though some makers add hardened surface treatments.
The Seiko SSB393P1 is a quartz chronograph in black titanium, and Omega makes the Seamaster Diver 300M 210.90.42.20.01.001 in titanium. Browse titanium watches in stock to compare. Watch Codex explains titanium grades, finishes and scuff resistance.
Gold
18k gold is 75 percent gold, alloyed with other metals for strength and colour. Yellow, rose and white gold can all be 18k: copper gives rose gold its pink, and white gold uses whitening metals, sometimes under a rhodium plating that can wear at the edges. Gold is heavy and softer than steel, so it collects fine marks with daily wear, but its colour runs all the way through. A 750 stamp marks 18k, though a stamp alone does not prove a watch genuine.
On listings, “18k”, “750” or “solid gold” means gold through the metal. “Two-tone” says only that there are two colours: the Rolex Datejust 16233 pairs steel with solid yellow gold, but on many cheaper watches the gold parts are plated, so check the case material. The Day-Date 18238 is solid 18k yellow gold throughout.
Coatings
Gold-tone, gold-plated, IP and PVD finishes are thin coloured layers bonded to a base metal, usually steel. They give the look of gold or black for much less money, as on the Citizen Eco-Drive Corso AW1232-04A, a gold-tone watch with a steel case, or a PVD-coated Tissot T-Race. Modern coatings are hard-wearing, but the base metal shows through first at the clasp, case edges and underside of the bracelet. Polishing cannot restore a worn coating; the part has to be re-coated or replaced, so ask whether the brand offers that before you buy.
Other materials
Ceramic is very hard to scratch but can crack if dropped; the ceramic watches guide covers what to weigh up. Bronze darkens to a brown or green patina with wear, and many bronze watches use a steel or titanium caseback so the alloy does not sit against the skin. Carbon composites are very light and do not corrode, but cannot be polished. On the site, the IWC IW387902 is bronze and the Panerai Submersible PAM01232 is carbon.
