Omega quartz watch has three small dials.

Omega quartz watches usually have three small dials because they have multifunctional and complicated movements. This kind of movement is called "chronograph", which can display time, stopwatch and timer at the same time. One dial shows stopwatch timing, and the other two dials are used to accumulate minutes and hours. Omega is a world-famous brand under SMH, a Swiss microelectronics and watchmaking group.
