I have been involved in perpetual calendar function of research and development, the truth shows that institutions such as the perpetual calendar is a model of complex, among the highest in the mechanical watch out complex function. It can make you very worry, every abortion don’t need your own thinking of the set-up calendar, the somebody else will automatically put the things to do. Only the general set-up of perpetual calendar cheap rolex watches is not literally can achieve, you need to seriously and carefully check specifications, then turn the handle in the very calm head or the press of a button calibration date, must have patience. I started to develop calendar in recent years, through my research for each brand calendar, found that the calendar shows the complexity of the function between ordinary calendar and the calendar, though not perfect, but very practical. I’m here is to popularize the knowledge of calendar related.
The concept of Calendar (Annular Calendar) wrist watch
Calendar watch calendar organization carry except in February (leap year 28 days, leap year 29 days) need to have a manual adjustment outside bottom, other 7 31 days monthly (January, march, may, July, August, October and December) and four 30 days of abortion (April, June, September 11 month) can be automatically identified. Calendar calendar organization carry, although cannot automatically identify common year February 28, or leap year February 29, but it will by artificial regulation in February to 30, so every year there will be five have 30 days to abortion and seven have 31 days monthly, so regular cycle make originally complex calendar conversion cycle becomes relatively simple, let the designers can be done by simpler institutions than calendar calendar function, at the same time cooperate with reasonable and humanized calibration device, for the general of the wearer, the charm of it seems to be no worse than calendar watches. In addition, because the calendar is can distinguish between the size of institutions, the wearer must know which month of the date at the time, and therefore have a calendar watchess must be equipped with month shows that institutions at the same time. It is obvious that compared with the ordinary calendar, in display to allow the wearer to get more information about time show, it was also one of the strengths of the calendar watches.
