Seller: challenge for your listing

Set the physical watch to the required time. Write your username, date, and Challenge ID by hand on paper, place the watch and note in one photo, and add the public record link or Challenge ID to your listing.

Create a public challenge record (Challenge ID and required watch time), then handwrite it next to the watch and include the Challenge ID in your listing.

Reddit username or seller name

Optional, but strongly encouraged. It helps match the challenge to a listing or conversation. Usernames are entered by the challenge creator and are not verified by WatchTimestamp. If provided, a username may appear on the public challenge record and PDF.
