Large military watch? I know you're not looking to spend a lot, but the ones I know cost a lot. Check out
Panerai
Bell & Ross
U-Boat
Those 3 are large military type watches. All automatics too.
But if from your post, you're looking for a good budget watch. So I would probably go with a Timex.

If you really want something nice. I highly recommend spending some cash on Seiko. Trust me when I say Seikos will last you as long as you live. They are great watches at a budgeted price.
