The WSSA0089 answers a question the trade had long stopped asking out loud: what happens when Cartier builds the Santos case from Grade 23 titanium? The material costs more per gram than 316L steel, yet it sheds roughly 30 percent of the mass on the wrist compared to the steel equivalent — a difference you notice after 20 minutes of wear and can't live without after a year.
## The Titanium Drop Cartier Never Really Announced
The collector community quickly settled on "Santos Grade 23" as shorthand for the reference, because Grade 23 titanium — also known as Ti-6Al-4V ELI — is significantly more corrosion-resistant and biocompatible than standard structural titanium. Cartier's own communication was understated; the secondary market's reaction was anything but: within the first three months of release, ask prices routinely ran 400 to 600 euros above the retail price at launch.
## What the Market Does With It Today
In 2026, the WSSA0089 trades in a stable range of 7,200 to 8,100 euros across the major platforms, depending on condition and whether full purchase documentation is present. This is not a speculation reference — the Santos segment is too broad and too liquid for that. Buyers here are acquiring a daily instrument in a material that feels different after 5,000 kilometres of wear than it did on day one: barely a scratch, no discoloration, the same matte finish.
Brand profile: Cartier
Cartier watches (Santos, Tank, Ballon Bleu) are popular counterfeiting targets. The characteristic design (Roman numerals, blue sword hands) is recognizable, but also replicable.
- Sapphire cabochon crown: on genuine pieces SET IN METAL (bezel setting), on fakes usually GLUED. Test: loupe — adhesive residue around the edge = fake.
- Bracelet screws: genuine Cartier ALWAYS has visible screw slots. Pins = fake.
- 'Swiss Made' at 6 o'clock: MICROPRINT directly below the 6 o'clock marker. Fakes often omit it or print it crooked.
- Guilloché pattern: under 10x loupe EXACTLY parallel and uniformly deep. Irregularities = fake.
Serial number format: Cartier serial numbers: alphanumeric on the case back. Older models: number between the crystal ring and case. Cartier Passport included with new purchase.
