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.

The Cyclos watch. The thing special about this watch is that the hour hand's length shrinks or grows, so that in AM it points on the outter circle and in PM it points to the inner circle.

Note that chronograph and chronometer has critical history and somewhat precise meanings. A Chronograph is a timepiece or watch with both timekeeping and stopwatch functions. A Chronometer watch is a watch tested and certified to meet certain precision standards. However, today, radio-controlled watchs makes chronometer obsolete. For detail about watches, see: Watch.
