-SeaGull USA is $229 and will be higher quality than just about anything else in that general range, it's very classic too; can be worn with any clothing and in casual or formal situations. Also automatic. If you want an automatic I can probably come up with a handful more suggestions, but the majority of mechanical watches that cheap will be unreliable.
Other than that most recommendations will be quartz (boo quartz!), and in that case it just comes down to personal preference in a ton of ways.
Things to look out for in a cheap watch:
- Make sapphire crystal a priority. Mineral crystal scratches a lot and looks ****tier.
- If it'll be your only watch, steel case and steel band. Keep it black or white faced.
- Less than a 38mm case will look small compared to modern style. Bigger than 44 will look huge. Ideal size is 40-42 on anyone with normal wrists.
Brands to consider include Seiko, Citizen, Wenger, Armani, basically anything you like for quartz. But keep the above in mind. Also, don't buy Invicta.
