Perpetual Calendar watches tend to be complex, expensive, laborious to adjust - and demand a winder so the owner needn’t fuss with it every day. The watch uses windows, hands or other displays to convey day, date, month, leap year, etc.
Not Seiko’s perpetual. It simply shows you the date (correctly). Every week, every month, every year. It’s driven by the “date-a-base” stored in its quartz movement. 
Housed in a titanium case, this watch is just right. It includes a GMT hand, sapphire crystal, 5-segment bracelet, adjustable clasp and classic dimensions: 38x10mm.
