The Santos WSSA0018 launched in 2018 as Cartier's complete Santos redesign. It uses caliber 1847 MC (in-house Cartier) and introduces QuickSwitch (strap change in 30 seconds without tools) and SmartLink (bracelet sizing by the owner).

US dealer asks of US$7,810–8,495 (Watchfinder, Gray & Sons, Luxury Bazaar) cap the high end. All are converted at ฿32.5/USD. They are US and international market figures, not Bangkok transaction records. The Santos is among the most traded Cartier sport references in Thailand:
- Low ฿210,000 — 2018–2020 references, worn, no box
- Median ฿230,000 — Full-set 2022–2023 with TH warranty
- High ฿255,000 — NOS 2024 with factory stickers
QuickSwitch + SmartLink
QuickSwitch is the strap-change system: press the button beneath each lug, pull the strap, install a new one. SmartLink allows owners to remove or add bracelet links via thumbnail-released pins.
The combination makes Santos a true "everyday luxury" — leather for business, bracelet for casual.
Santos Large vs Medium
| Size | Reference | Median Bangkok 2026 |
|---|---|---|
| Large (39.8mm) | WSSA0018 | ฿230,000 |
| Medium (35.1mm) | WSSA0029 | ฿210,000 |
Large trades more often. Medium is the choice for female wearers and smaller wrists. The WSSA0029 figure is the Loupe market value (US$6,522, 15 October 2026) and the 5D Watches guide (about US$6,551) converted at ฿32.5/USD. The Medium trades about ฿20,000 below the Large, not above it.

WSSA0018 Authenticity Checkpoints
- Bezel screws — eight screws on the bezel with slots aligned parallel (hand-finishing detail). Fakes commonly show misaligned slots
- Caliber 1847 MC — Cartier's in-house automatic. Cartier specifies a solid steel caseback on the WSSA0018, so the movement is not visible; a WSSA0018 with a see-through caseback is not original to this reference
- Roman numerals — Cartier uses "VII" at 7 o'clock (correct roman convention is also VII). Fakes occasionally use IV at 4
- Seven-sided crown set with a faceted synthetic spinel — Cartier's own specification for the WSSA0018; a smooth cabochon stone or a different crown shape is a reason for suspicion
Santos in the Thai Market
Santos buyers in Bangkok tend to fall into a few groups:
- "Cartier completists" who own Santos + Tank + Ballon Bleu
- "Rolex alternative" buyers who don't want to wait for Submariner allocation
- Wedding gifts
- Upgrades from older quartz Santos
