Anthony Dawson wears an unidentified watch

Dial M for Murder (1954) is Alfred Hitchcock's thriller about a husband's scheme to have his wife killed. Charles Swann (Anthony Dawson), the man hired for the job, checks his wristwatch as he approaches the apartment, timing his entrance to the plan. The watch is shown in close-up, a round field-style watch with a pale dial, Arabic numerals, and a railroad minute track on a fabric strap, no maker legible, so it is recorded as an unidentified watch with the frame kept as evidence.
