From the first photo to the listing: this is what happens to a watch once it's in Cronofolio.
Add · One photo: it knows which watch it is, and what shape it's in.
If you collect watches, you already know where the information ends up.
The price in a note. The service in a receipt. The reference in a screenshot. Photos scattered across your phone. Once you're past two or three watches, keeping it all in your head stops working.

How it works, watch by watch
Take a few photos. That's where it starts.
Cronofolio tries to recognize the model and reference. If it isn't sure, it says so and lets you choose from the likely options.

Moonwatch · 311.30.42.30.01.005
Paid €4,300. Actually cost €4,950.
The purchase price is only the start. Shipping, customs, a service, a refund — Cronofolio keeps the real running total, not just the one on the listing.
Three years from now, you won't have to remember it all.
Service, documents, condition and receipts stay attached to the watch — not scattered across email, drawers and old chats.
It's worth €5,400. But what's actually happening on the market?
Asking price, comparables, value over time — kept distinct, not averaged into one guess.
When you decide to sell it, you're not starting from zero.
Photos, history, real cost and asking price are already there. Generate the listing and track where it's posted.
