In the referenced video, there's a clip from the movie Glory where a fair-skinned hand with a digital watch is in the frame. I like to think this must be a glib reference to Blake Edward's' The Party (1968) in which Peter Sellers dresses in dark face to play Hrundi V. Bakshi, who is introduced as a hapless Hollywood extra on the set of an Alamo-style Western. After a cut, the director asks Bakshi what time it is and Bakshi looks at his huge underwater wristwatch to tell him the time, then sheepishly realizes his mistake as the director goes apoplectic.
