So-called "atomic wristwatches" keep the best time.
They keep time as well as quartz wristwatches during the day,
and they receive radio transmissions at night with the correct time.
All "quartz wristwatches" keep excellent time -- they drift less than 15 seconds a month when they are worn (kept close to body temperature) -- even low cost watches well under $30.
Analog quartz watches and digital quartz watches have the same accuracy.
Mechanical watches are not as accurate as quartz watches.

I have a gold seiko. It is a great watch, it keeps time well and looks very good. It was about $150 dollars. It really is a great watch for every occasion.

A watch winder is used to keep your automatic watches working if you do not wear them on a regualar basis. It provides the motion that is necessary to keep a watch working and keeping time. You place your watch on the watch winder, and it will create a motion that will allow the watch to keep time and continue working. These are not a necessity, and if you wear your watch regularly you would not need one. It is great if you have a special watch that you may only wear on special occasions.

Jewel movement refers to the mechanism by which the watch keeps time, and is generally a selling point owing to its accuracy.
The best thing you can do is not to slam the watch around too much. There is a plastic case inside which keeps water out of the watch, and if it cracks, it will no longer be waterproof.
