A character glances at their watch for the time, usually during tense situations where a deadline is looming or to show the character's growing impatience.
Then the Fridge Logic hits you: Since when has this character ever worn a watch? In this trope, a character will suddenly have a wristwatch or other accessory worn merely for a single use, after which the article will be immediately forgotten. In extreme cases, the watch in question is obviously seen not on the character's person before and after its use. Although it can be justified by cleverly hiding such with long sleeves and other concealing clothing.
Sometimes sarcastically defied with a character who isn't wearing a watch looking anyway and commenting, "wrist-o-clock" or something to that effect.
Subtrope of The Law of Conservation of Detail. See also Chekhov's Gun, Schrödinger's Gun. See Sudden Anatomy for this trope applied to body parts.
Examples:
- In episode 1 of Fun Alliance, Lightning Deer checks the time on a watch that appears on his tail. It shows up again on one of his legs when he tells Thunder Mouse he has no time be slowed down.
- Lamput:
- In "Airport", Specs Doc looks at his watch along with Skinny Doc while both are on the airplane. The watch appears out of nowhere since Specs Doc typically has nothing around his arms.
- In "Skinny's Dance Night", a hammerspace wristwatch appears a few times. First, a watch appears on Skinny Doc when he realizes he's late for his dance practice; a watch appears on Lamput before he realizes Skinny Doc is late for his date; and a watch appears on Lamput again while he's attempting to wake up Skinny Doc.
- In "Lamput & the Elephant", while the docs are waiting for Lamput to fall into their pitfall, a watch once again spontaneously appears on Specs Doc's arm so he can check the time.
- In "Animal X", a wristwatch appears on Specs Doc's arm out of nowhere as he waits for Skinny Doc to stop struggling to lure the gorilla out of the cage.
- In "Tall Tales", during part of the docs' lie's visuals, Specs Doc spontaneously gains a wristwatch when he realizes he and Skinny Doc are late to getting to the laboratory.
- One Calvin and Hobbes strip has Hobbes check his watch, despite usually not wearing anything at all, being a stuffed tiger.
- Animorphs: One meeting with the Drode sees the alien suddenly pull an oversized wrist watch out of nowhere to remind them that his Deal with the Devil is temporary. Not played for laughs, it's the Drode reminding them he (or rather his boss Crayak) is a Reality Warper.
- Averted in Jim Butcher's Ghost Story. Dresden glances at his wrist, despite not actually wearing a watch (Harry's Walking Tech Bane status prevents him from wearing one). Another character calls him out on this.
- Harry Potter somehow acquired a muggle wristwatch after he left the Dursleys (it's mentioned that he wished he had one as he had no way of measuring the passage of time during the long hours he was locked away in the cupboard under the stairs). It stops working when he goes diving in the lake for the second task of the Triwizard Tournament. The Weasleys later give him a pocket watch that used to belong to Molly's brother for Harry's 17th birthday.
- Given the usual absurd turn in The Goon Show:
Seagoon: Right - run my bath.
Moriarty: Don't be a fool - this is no time to take a bath, it's getting late.
Seagoon: Nonsense - plenty of time - according to the hairs on my wrist it's only half past ten.
Grytpype: (disbelief) The hairs on your wrist say half past ten?
Seagoon: Yes.
Grytpype: You must be mad.
Seagoon: Why?
Grytpype: The hairs on my wrist say eleven-thirty.
Moriarty: I can vouchsafe for that, he set them right by the hairs on Big Ben this morning!
- The Amazing Digital Circus: In "Fast Food Masquerade", during the scene where Jax asks Gangle if the wall clock is broken because it hasn't moved, a watch suddenly appears on Gangle's left arm for her to look at and realize the wall clock really is broken at the end of her existential rant.

- In "Unwanted Guest", Lila stares at her watch after realizing how long Dexter has been in the attic. It stays on her wrist as she walks out of frame, but disappears after this scene.
- Don't Hug Me I'm Scared: In "TIME", Tony lifts up Yellow Guy's wrist to make a point about time, showing a watch. The watch prop was made just for that scene, and is not part of Yellow Guy's puppet. Humorously, when DHMIS was retooled for its television run, the watch was made a permanent part of Yellow Guy's design.
- Subverted on Camp Lazlo: While Raj and Clam are waiting for Lazlo to resurface from snorkeling, Raj questions how long has he been under. Clam looks at his wrist, which has nothing on it, and remarks "Don't have watch".

- Downplayed in Gravity Falls: Dipper wears a digital wristwatch for a single episode and is never seen with it ever again.

- In "Too Many Pinkie Pies", when all of the Pinkies are challenged to seeing who can watch paint dry the longest without moving or talking, it turns out to drag on a bit longer than expected; during one of the time skips, Rainbow looks at an actual wrist(?) watch she never had up until that point and is never seen again from then on.

- Patrick does this thrice in SpongeBob SquarePants.
- In "Squidward the Unfriendly Ghost", he checks his watch after Squidward asks if he knows what time it is. It's actually a cruel joke by Squidward: Patrick's holding his bottle of bubble soap with the same hand the suddenly materialized watch is on, so he accidentally spills it when he turns his wrist.
- In "Patty Hype", the watch is quite clearly drawn on his wrist (he draws a new battery for it).
- In "New Student Starfish", he hangs a lampshade by asking, "When did I start wearing a watch?"
