If you keep up with the industry, it can feel like watchmakers are always championing an exotic new material from which they’ve crafted their latest timepiece. The Earth’s crust and the outer reaches of the periodic table are routinely plundered in the name of turning up a slightly tougher metal alloy or a more vividly decorative dial. Even materials from outer space are fair game, with meteorite dial inlays highly prized by collectors. And we haven’t even got to the myriad polymers that can be dreamed up in labs across Switzerland. Whatever went wrong with stainless steel?

The short answer is: nothing. But there is a metal that represents a proper upgrade on steel without leaving you feeling as if you’ve been bamboozled by marketing spiel. Titanium has been around in watchmaking for over half a century, starting with the Citizen X-8 from 1970, but it can feel like a 21st-century innovation. It’s laborious to machine, so no one was producing titanium watches in serious volumes until much more recently.

Technological advances have made it easier to produce watch cases and bracelets in the metal. Naturally, its strength is the main reason it’s so sought-after. Grade 5 titanium – the most commonly used alloy – is roughly twice as tough as stainless steel. It’s also hypoallergenic and less sensitive to heat – all qualities you’d welcome in a watch. And titanium’s suitability for making sports-style watches was given a boost when Rolex introduced its first titanium production model. Often, you’ll find titanium watches given a matte texture that befits the metal’s utilitarian qualities, but it can be polished (at great effort) to the point where it’s almost indistinguishable from steel. Finished in this way, a titanium watch is a stealth upgrade.
