All of the watches from the various suppliers are the same. The only difference is the price.
There is a lot of difference in their quality, even when they are the same price from a given supplier. Some have metal backs, some have plastic backs, some will have better plating than others, some are plated over pot metal, and some are plated over a brass bezel. Sometimes the supplier identifies those with a brass bezel, and sometimes they don't. Brass is worth the extra cost. Some of them have a glass crystal, and some of them are the cheapest plastic. Some are made by Seiko, and some are generic Chinese. If you order a variety of palting and dials, you will learn the differences. Unfortunately, the faces that people like are those that are the cheapest quality. The better watches are only with plain number dials.
A new battery will last for about 2-years. Some of the watches have a tab under the winding stem that keeps it from running. Those that don't began running when they left the factory, and the batteries may be near their end. I buy the watches from Klockit and replace the battery at the time of sale. A new GE battery is about $1.00 from Klockit. They all share the same battery.
