The Cartier Santos needs no introduction. Since Louis Cartier designed it for aviator Alberto Santos-Dumont in 1904, it has remained one of the most recognizable silhouettes in watchmaking. But with the introduction of the Large Model Ref. WSSA0089 in full titanium, Cartier has taken a centuries-old icon and given it a decisively modern, industrial edge.
For collectors and enthusiasts who appreciate heritage but crave technical wearability, this specific reference is a revelation. Here is a closer look at what makes the titanium Santos a standout piece for any serious collection.

The Material Mastery: Grade 5 ELI Titanium
The most dramatic shift in the WSSA0089 is the case material. Moving away from traditional stainless steel, Cartier opted for Grade 5 Extra Low Interstitial (ELI) titanium, also known as grade 23.
This specific alloy is incredibly resilient, but its real advantage on the wrist is the weight. While the steel large model weighs in at around 145 grams, this titanium configuration drops the total weight to under 100 grams. The result is an oversized, commanding sports watch that wears with featherlight ergonomics.
Moreover, Cartier didn’t just change the metal; they also changed the finishing. Replacing the traditional heavy brushing, the titanium surfaces feature a matte, bead-blasted finish that gives the watch a muted, architectural look. This is beautifully contrasted by the wide, high-polish bevels on the edges of the case and the signature exposed bezel screws.

Monochromatic Details
To complement the stealthier case, Cartier tweaked its signature dial DNA. The WSSA0089 features a silvered opaline dial paired with blued-steel sword-shaped hands and classic black Roman numerals.
However, the most subtle—and perhaps coolest—update is found on the heptagonal crown. Instead of the traditional blue sapphire cabochon, Cartier set the WSSA0089’s crown with a faceted black synthetic spinel. This monochromatic shift ties the muted grey of the titanium together flawlessly, giving the watch a more utilitarian, aggressive stance without sacrificing the Maison’s inherent elegance.

The QuickSwitch Advantage
Versatility is paramount in modern horology, and the WSSA0089 delivers heavily on this front. The watch comes equipped with Cartier’s proprietary “QuickSwitch” interchangeable system.
Out of the box, the watch includes both the integrated titanium bracelet and a secondary nubuck alligator leather strap equipped with an interchangeable steel deployant buckle. Because you can swap the bracelet for the strap using nothing but your fingernail, the watch transitions seamlessly from a high-tech daily driver to an elevated evening piece in seconds.
The Verdict
The Cartier Santos WSSA0089 proves that you don’t have to rewrite a design completely to make it feel entirely new. By introducing high-grade titanium, altering the finishing techniques, and leaning into a monochromatic palette, Cartier has created a piece that respects its aviator origins while firmly planting itself in the future of luxury sports watches.
