On the low end, you could probobly get a decent Ramond Weil or a Movado. They have 5-800 dollar watches that look decent an are professional looking. On the upper end (and in some cases just a bit beyond your budget) you could look at an Omega or a Tag Heuer. If you can find someone you can negotiate with you might be able to get a base Breitling but they typically fetch around $1700 base.
