Seiko 5 Automatic 21 Jewels SNK621 SNK621K1 SNK621K Men's Watch

This one is famous for its long-term accuracy; an excellent aggregate drift of 13 seconds every month. Plenty hard case, it’s even, attractive and don’t scratch too easily. So is the Hardlex crystal glass. The lumes are efficient, if not outstanding. It’s the even laying that does it and the 7S26 caliber needs just a couple of twirls to be initially charged after a prolonged resting period. It will not need any further special attention.
