automatic, under 300 bucks,
check certina, tissot, Seiko, Orient,
beware of those automatics off ebay, most of chinese with cheap chinese movement with doubtful reliability, in a spanish watch forum i hang around they made a group buy for a brand called parnis, the watches arived and a few weeks in, the quality was starting to show,
personaly, check out all the watch of the day deals, and maybe have a look at boris afordable watches, (i know, it sounds dodgy, but its a good source of japanese automatics) just look for seiko5ers,
