I wear a Hamilton Khaki Field Mechanical, it's a simple design Flierger style watch. A replica of the watch they made for WWII soldiers. For under $300 you have an ETA Swiss movement, 17 jewels for a hand wind, you have a sapphire crystal and it's water resistant to 50 meters. You can easily change the strap and use a Nato strap or a german leather Bund strap. It's neither a dress watch nor a bulky sports watch so it's still elegant and the dial is very readable. When I don't wear it, I lay it down vertically, crown left (upside down) so that the movement slows down during the night. This way it's about as accurate as a quartz watch.

I also have a cheap digital Casio watch with a battery that will last probably about 10 years. My principle is quartz with battery watches are digital, but analog watches are mechanical, either automatic or hand-wind.
