Time Synchronising thingy for dreamcast?

[Strik3r91]

Hi people! I was watching old vids from Japan's Dreamcast launch (1998-1999) and found interesting thing in the video below.
On the time 1:35 the man is sticking their watch to a platform that is connected (?) to a dreamcast unit and time synchro page appear on the screen. Have you ever heard of it before?

Probably a prototype of that SWATCH thingy, as the SWATCH logo is even on the screen.
