These pocket watches were issued for use for railroad workers in the first half of the 20th century. The ability to keep accurate time was essential in a profession that relied on transport punctuality. The little safety hook you see in the video was devised to prevent railway staff from accidentally altering the time. In many cases, a thin strip of paper was also added by the railway's supervisor, to ensure that none of his employees had tampered with the time. A damaged piece of paper would confirm this. The case maker is Fortune, a Canadian company, and this pocket watch was most likely used on Canadian railways.
To listen while using other apps, switch the player to Picture-in-Picture (PiP) during playback — it keeps playing in a small floating window (the screen stays on).
To listen with the screen fully off, in-browser playback stops by YouTube's design. Open the video in the YouTube app to keep listening where background playback is supported (e.g. with YouTube Premium).
