Seiko Seiko 5 Sports SRPK31

Seiko 5 Sports SKX Mid-Size. With vintage styling and colors recalling the quartz diver’s watches of the 1980s, the mid-size SKX design offers the 38mm case diameter of the originals, but with a slimmer case and a durable, yet comfortable, three-row sport bracelet. Providing automatic technology that you control with every movement, this dynamic timepiece is powered by a 24-jewel movement that beats at a frequency of 21,600 vibrations per hour, with a power reserve of approximately 41 hours and manual winding capability. The ivory dial, framed by a dark gray uni-directional rotating elapsed timing bezel, features a day/date calendar and luminous hands and markers. In stainless steel, with locking tri-fold push button release clasp and a screwdown see-through caseback for a view of classic timekeeping in action. 10 bar, 100M Water Resistant
