SEIKOSieko Men's SNKK86 Stainless Steel Analog with Black Dial Watch

It is a good looking watch not a big and heavy one. I had seiko watches before one biggest problem with these self winding watches are, when these watches get 10 years old the self winding function becomes weak and as soon you take it off your wrist it will stop moving within a day but when its new it does not stops for a weeks. This one seems new model to me so I don't know if company made any changes in their winding mechanism or if its still the same.
