The Watch ID System
Every watch on W&F receives a permanent digital identity. An NFC chip embedded in the physical watch links to a blockchain-backed provenance record that tracks ownership, stories, authentication, and royalties across its entire life.
WF-YYYY-BRD-NNNNN
Every Watch ID follows a structured format that encodes the registration year, brand code, and a unique five-digit serial number. Readable by humans and machines alike.
Identifies this as a Watches & Family registered timepiece.
The year the watch was first registered on W&F. Not the year of manufacture.
Three-letter code for the manufacturer. RLX = Rolex, PP = Patek Philippe, AP = Audemars Piguet, etc.
Five-digit unique serial within the brand-year combination. Sequential, non-recyclable.
NFC chip. Tamper-evident. Physically bonded.
The Watch ID isn't just a database entry. It's a physical NFC chip embedded in the caseback or strap clasp of the watch itself. Tap your phone to the watch and instantly access the full provenance record.
Tap to verify
Hold any NFC-enabled phone to the caseback or clasp. The chip responds with the Watch ID and a link to the full provenance record. No app required.
Tamper-evident
The chip is sealed with a tamper-evident adhesive. If someone removes or replaces it, the seal breaks visibly and the chip reports its integrity status as compromised.
Blockchain-anchored
The NFC chip stores a cryptographic hash that links to the on-chain provenance record. The chip alone proves the physical watch matches the digital identity.

Four layers of provenance data.
The Watch ID links to a comprehensive provenance record stored on-chain. Here's what's recorded for every registered watch.
Ownership Chain
Complete record of every family that has owned the watch through W&F. Includes acquisition dates, sale dates, transaction prices, and chain position.
Family Stories
Every owner writes their story. Why they bought it, what it meant to them, why they're passing it on. These stories are immutable once written — they travel with the watch forever.
Authentication Records
Every authentication event is logged: initial verification, condition assessments at each sale, service records, and any modifications. Timestamped and signed by the authenticating party.
Royalty Distribution Ledger
Full record of every royalty payment triggered by the watch. Which families earned how much, which tier was active, and the decay factor applied. Fully auditable.
