The Yes Watch is quite special. It features a analog face with numbers 1 to 24 and a single pointer. The background is a digital display that darkens parts of the dial where sun is supposed to be below the horizon. So, you can tell night and day by a glance. A digital readout also gives the precise time.

Note that chronograph and chronometer has critical history and somewhat precise meanings.

However, today, radio-controlled watchs makes chronometer obsolete.
