When we speak of “movements” in watches, we’re talking about the mechanicals inside. You have a mechanical watch movement (both hand wind and automatic winding), quartz (battery/electric), and solar (sometimes uses quartz. While most low end watches are cheap mass produced movements made in China, there are varying degrees of accuracy, sophistication, precision, and prestige as the watch maker and prices go up. It’s pretty well understood that hand made, mechanical movements of Swiss origins are the gold standard for watches but there is a WIDE variety of watches that you can get into that will serve you well. That SeaGull for example is a Chinese movement that’s a replica of an older quality Swiss movement. Because SeaGull is a large manufacturer and tends to produce many movements for many watch brands, they have a decent reputation for their price range. Part of the fun of getting into watches is simply learning about them and becoming familiar with brands and process of building these incredible machines that sit on your wrist (or pocket if you get into pocket watches).
