Buster Keaton wears an unidentified watch

The Twilight Zone (1959) episode "Once Upon a Time" stars the silent-film legend Buster Keaton as Woodrow Mulligan, an 1890s janitor who time-travels to the noisy present. He checks his pocketwatch and warns that he has only fifteen minutes, the open-face watch filling the frame: a white dial with Arabic numerals, a small seconds register, and a chain. No maker is legible, so it is recorded as an unidentified pocketwatch with the frame kept as evidence.
