Seiko 5 Sports Military Automatic SNZG09K1-var-LS20 100M Men's Watch This is certainly not the best among mechanical watches ever, but you will be stunned at the quality this watch exudes. Very slightly on the thicker side, it looks good on those with thin arms and just right on burly hands. So, none has reasons to agonize. It’s a good choice if you’re trying to access the upper-entry level automatic watches with a workhorse movement for less than reasonable price.
