Yes you were right, it was the solution :

user.seen files uses unique IDs stored in the cyrus.header file

Therefore, restoring only user.seen file will not work if a reconstruct
was done in-between, because the ids will not correspond anymore.

The solution is therefore to :
1. Stop cyrus
2. Restore a user.seen from backups (it's ok if not very recent, emails
read since then will simply become "unread")
2. ALSO RESTORE cyrus.* files in the folder that were backup at the same
time of user.seen ! (To be sure unique ids will correspond.)
3. reconstruct mailbox : it will use data from backups and add the
emails arrived inbetween as unread.
4. Restart cyrus
