What's the difference between an quartz, automatic and mechanical luxury timepiece?

The three types of watches, automatic, mechanical and quartz. Quartz is the easiest of all. That's a battery operated watch. Whenever you look at the face of the watch you'll notice that second hand goes tick, tick, tick, because of the pulse. The quartz will always be the most accurate watch that you buy. Now the more traditional, the automatic and mechanical. The automatic has a fly wheel in the back of the watch and as you move your arm, it spins and it winds the main spring inside that watch. Just like a human being breathes, that coil breathes also. As you go through your day it will wind up and tighten up and it will loosen and relax when you are not in motion. So it will keep that fine mechanism going. Some of these time pieces have more than 256 moving parts inside. Mechanical is probably the oldest of all. Your grandfather's watch, have you even seen him wind it? Well that's a mechanical. Where an automatic will wind itself and you can also wind it, but a mechanical you have to wind because it will not wind itself..
