For owners
Proof it is genuine
One tap confirms the piece against its secure chip — no paperwork, no appraisal.
Full history in one place
Caliber and complication record, ownership transfers and every service entry.
Protected resale value
Any buyer verifies in seconds, so a verified piece never trades at a doubt discount.
Access only owners get
The physical tap unlocks allocations, private viewings and direct concierge.
For brands & retailers
Super-clones stop working
A replica can copy the case to the milligram. It cannot produce the private key.
A direct line to every owner
The piece stays connected through resale, so the second owner is still your client.
Service and warranty, automated
Workshops check in a piece by tapping it. The ledger updates itself.
See where pieces surface
Every tap is a signal — grey-market movement and theft become visible.
Stolen Watch Registry & Global Radar
Mark a piece stolen and its passport locks instantly. The next unauthorized tap flags itself.
