Seiko Premier Perpetual Calender SNQ145 SNQ145P1 SNQ145P Men's Watch The Perpetual Calendar speaks for itself; it is designed to run correctly till the year 2100 without any sort of user intervention once it’s set. This is a stark contrast to the rest of the budget watches out there; moreover, it’s the seconds-hand that denotes which month it is at the press of a button. Overall, a sophisticated watch that doesn't go overboard either on price or on the looks.
