Hamilton Intra-Matic
Two size to choose from 38mm & 42mm, leather strap, round, classic American vintage styling, sapphire crystal, good Swiss made automatic movement, and a price that definitely within your range.
side note: Do try both size, as it is an all-dial watch, it wear bigger than espected, so maybe you will prefer 38mm more than the 42mm.
Have a nice day.
