Frequently Asked Questions
How does photo identification work?
Our AI compares dial, bezel and case details against 50,000+ verified references to return the closest visual matches. Ideal for collectors verifying listings or resellers identifying unknown models in seconds.
What kind of data is available?
Each reference includes normalized specs—brand, model, reference number, case size, materials, movement, retail price and photos—plus live market valuation ranges gathered from trusted marketplaces.
Everything is structured, searchable and exportable.
Can I track my own collection?
Absolutely. Add your watches to a private dashboard, see value changes over time and attach receipts or photos. You can export reports for insurance, resale, or personal records—your data stays yours.
How is my data protected?
Privacy is built in. WatchReactor uses local or anonymized storage by default, so your collection data and images stay under your control. You can export or delete everything at any time—no lock-in, no tracking.
Is there an API for developers?
The same verified dataset that powers the app will be available via API for professional or commercial use. Developers and resellers can integrate watch specs, images and valuations into their own tools or marketplaces. Paid tiers will support large-scale access once public.
How is WatchReactor different from Chrono24?
Chrono24 is built for buying and selling. WatchReactor is different—it's a neutral, privacy-first data platform made for collectors who want ownership and accuracy.
No ads, no lock-in, just reliable specs, values and exports you control.
Own your watch data from day one.
