What transfers with your watch, and what stays private

A watch passport is not one undifferentiated pile of data that follows the watch around forever. It contains two distinct kinds of information, built around a simple rule: information about the watch itself can move with it from owner to owner, while information about your own relationship with the watch stays private to you. This guide covers what falls on each side of that line, why the distinction exists, and what it means in practice when a watch changes hands.

What is transferrable?

Transferrable information is part of the watch's ongoing record. It travels with the watch through an ownership change and remains available to whoever owns it next. On WatchPassport, this is the information under a passport's Identity tab and most of the information under a passport's Timeline tab.

That includes the watch's identity, such as its brand, reference number, serial number, movement type and other specifications, its identity photographs, any accessories on record such as the box, papers or extra straps, and its timeline of events such as services, pressure tests, timegrapher readings, battery changes, and previous ownership transfers.

The reasoning is straightforward: this is information about the watch itself, not about any one person who happened to own it. A service performed three owners ago can still be useful to whoever owns the watch today, in the same way that a car's service history remains relevant when the car changes hands. Starting the record over with every new owner would lose much of the history that makes the record useful in the first place.

What stays private?

Private information stays with the person who created it and is not transferred to a future owner. On WatchPassport, this is the information under a passport's Personal tab.

That includes your acquisition record, such as what you paid, whether the watch was bought, gifted or inherited, and when and where you acquired it, as well as private notes and photographs.

This split exists deliberately. What you paid for a watch is information about your own transaction, not something that needs to become part of the watch's transferrable record. The same applies to personal notes, memories, photographs, or anything else you recorded for yourself.

Past owner identities are private too. A future owner can see that the watch has had previous owners and can see the transferrable events recorded during those periods of ownership, but not who those owners were.

Why does the line sit there?

The basic question is: does this information describe the watch and what has happened to it, or does it describe one person's relationship with it?

Service history, identity photographs and accessories describe the watch, so they can travel with it. Second-hand acquisition price, personal notes and owner identity belong to an individual's period of ownership, so they stay private.

What happens to private data when a watch is transferred?

It stays with you.

When an ownership transfer completes, your private notes, photographs and acquisition record remain tied to your account rather than transferring with the watch. The incoming owner receives the watch's transferrable record and starts with a Personal tab of their own.

As a past owner, you can still access the private information you recorded during your ownership. The new owner cannot see it, and you cannot see whatever private information they go on to add during theirs.

The watch's history can therefore continue from one owner to the next without requiring each person to give up the parts of their own record that were never meant to travel with it.

How can you tell which is which while using the app?

Look for the transferrable and private indicators next to fields and sections throughout the app. They show whether the information you are looking at will travel with the watch or remain private to you.

The Identity tab is transferrable, while the Personal tab is private, so the tab itself is usually the clearest indication. The individual indicators are particularly useful in places where transferrable and private information appear close together, such as on the Timeline tab.

If you are ever unsure, the basic rule is simple: information about the watch and its history belongs with the watch; information about you and your own ownership stays with you.
