RK S600 Complication Annual Calendar 46mm 18 K Rose Gold Case (only one made / Year ) The annual Calendar The question of always giving the right date was a weak point in calendar movements Because 7 months of the year have 31 days and 4 months have 30 days, February has 28 days for three years and 29 days every four years (leap year). The annual calendar adjusts automatically one or two days ahead, depending of the month with 30 or 31 days. Once a year the annual calendar needs to be adjusted manually, between the end of February and the first of March. In addition, the order of the months with 31 or 30 days is uneven, witch makes it solving the problem even harder. Watch Functions : Number Month Indicator at 3 , and a second Month Indicator (in letter type) and Day (in letter type) at the two Windows at 12 + Pointer-Date and Moon-phase at 6 and small seconds Hand at 9 The Month indicator at 3 or Clock is an additional Month indicator in Numbers 1-12 . (1 for January 2 for February etc... when Number 2 appears in red,it will be February ( this indicator is designed to remind you for the Month of February, in order to make the Annual Yearly Date correction for the following Year a head The RK S600 is also available in a manual Calendar ( you have to adjust the Calendar every Month with the Pushbuttons by Hand for the correct Calendar Function )
