WIS: Watch Idiot Savant. Someone who knows way more than is normal or reasonable about watches. Used in a self-deprecating way in reference to oneself and fellow watch enthusiasts. Most often seen on older watch forums like Watchuseek or Rolex Forums as opposed to Instagram, Reddit and YouTube. Watchnerd is a similar, more modern term. (You are now on your way to becoming one.)
Example: I divorced my husband after he became a WIS and began referring to our children exclusively as reference numbers.
Wrist Check: When watch enthusiasts share with each other what watch they are wearing at the moment, usually reserved for those presenting to a wider audience, such as on a YouTube video or podcast.
Example: They forgot the wrist check on the podcast and now I can’t sleep.
Wrist Roll: A video or gif that begins with a view of a watch on wrist, clasp side up, wherein the wearer then slowly rotates their wrist until the watch’s dial is in full view. Works best with flat-link bracelets that “play with the light.” Generally pointless with straps. Derided by many, particularly if the video is painstakingly slow.
Example: I don’t usually do wrist rolls, but I couldn’t help it with the Christopher Ward Twelve.
