Seiko 5 Sports Automatic Polyester SNZG15K1-var-NATO27 100M Men’s Watch The SNZG15 is a larger version of the standard Seiko 5 and is held to be one of the most affordable and popular automatic watches in the market. It has a long list of features that come for a price that don’t agonize you; neither does it make you feel pain over the bumps it faces or scratches it will accumulate through extensive use. It is a sub-$200 watch that, on paper, compares favourably to some watches costing in four figures.
