Watches

Casio A168W-1: In season 2, episode 14 at 02:42, a Casio-branded metal-bracelet digital watch is shown. The watch-spotting discussion identifies its Illuminator marking, bracelet, and button labels with the A168W family. Treat this as a real-adjacent A168W-1 match rather than a confirmed production reference.
