This weapon functions identically to the Invis Watch.
It is awarded to players of Poker Night at the Inventory for defeating Tycho during a round in which he has bought in with the item instead of cash. As of May 23, 2019, the game has been removed from sale. However, any owners may still obtain its promotional items.

| Special Item: Tycho|
Knock out Tycho after he's bought in with his special item.
- The Enthusiast's Timepiece was added to the game.
- [Item schema update] The Enthusiast's Timepiece could no longer be obtained via the item drop system or crafting.
- While invisible, Spy receives 20% less damage from all damage sources.
- While invisible, Spy has reduced timer on debuffs (fire, Jarate, milk, bleed).
- The Cloak meter displayed on the watch does not properly correspond to the actual amount of Cloak available, similar to Dead Ringer.
- When Tycho first shows the watch to Gabe, the co-star of the Penny Arcade webcomic, Gabe kills Tycho to obtain it. The watch has since changed hands repeatedly through the characters murdering each other. 
- The Cloak meter emulates the Pac-Man derived logo commonly seen worn on Gabe's shirt as well as a tattoo on his arm.
- The version of the watch presented in Poker Night at the Inventory is stained with blood on the left of its face. However, the version obtained in Team Fortress 2 does not have blood.
- If the Heavy wins the Enthusiast's Timepiece he announces to the table; "I will put this in my box of things I collect from dead enemies."
