摘要：The month indicator (22) is divided into equal sectors with a sector for 31 daymonths and two sectors for months less than 31 days. It has a wheel (48) which has asmany teeth as the sector indicator (22). The wheel (48) is connected to the day of monthwheel (18) by a third kinematic link (28,46) and to the day of month indicator by a second

kinematic link (24,36,37,48). The date mechanism includes: (a) a date wheel (18) ,driven bythe watch movement, which makes one revolution in 24 hours; a day of month indicator(20) fitted with thirty one teeth and controlled by the date wheel (18); a first kinematiclink (30,38), temporarily connecting, at the moment of change to next day, the wheel (18)to the indicator (20), so as to ensure a one step advance of the latter; a month indicator(22), and; a second kinematic link 24,36,37,48) temporarily connecting, at the end of eachmonth, the indicator (20) to the month indicator (22) to ensure a one step advance of thelatter at the end of each month; in addition a third kinematic link (28,46), temporarilyconnects the wheel (18) to the indicator (22), at the end of 31 day months and after thesecond link has ensured a one step drive of the indicator (22), so as to drive at least asupplementary step for the indicator (22), and via the second link (24,36,37,48), theindicator (20).
