FAQ

Questions

What is 28Chrono?

28Chrono is a watch sourcing platform for professional dealers. We use AI to organise offers from 300+ dealer trading groups so you can search by reference, compare prices and contact sellers directly.

How is this different from checking groups myself?

You don’t need to join hundreds of groups. We map every way of writing a watch to its standard reference and show all offers side by side, with the original message kept.

Can I try it for free?

Yes. Sign up free with no credit card and see the first 6 results of each search, with seller contacts.

Do you guarantee authenticity or stock?

No. 28Chrono provides market information and contact tools and is not party to any trade. Confirm authenticity, condition, price and delivery with the seller.
