Excuse me, is this Casio watch a perpetual calendar? Is it necessary to adjust the date for every abortion? Or do you need to adjust the date every four years in a leap year?

There may be no problem with this 400-plus model. You can see if the appearance is intact and the words on the dial are clear. No matter what the price, the appearance and workmanship of genuine watches should be very good, and the difference in price is only the difference in materials and functions. The date of this model should be manually adjusted in abortion, and the perpetual calendar of the pointer will not be at this price. Note that it is best to adjust the date in the morning, not at night, because the gears that change the date at night have already started to couple, so the adjustment is prone to problems, and the date conversion time will be chaotic in the future.
