What a Santos Large WSSA0018 Clears for in Bangkok — June 2026
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).
Thai Watch Market drawn from our work in Bangkok's pre-owned market Jan–May 2026 — Santos is the highest-turnover Cartier sport reference in Thailand:
- Low ฿240,000 — 2018–2020 references, worn, no box
- Median ฿275,000 — Full-set 2022–2023 with TH warranty
- High ฿315,000 — 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.
