摘要： A timepiece with a date display comprises two supports (20, 30), for example discs or rings, which are superposed, each bearing a series of marks (40, 50) in an annular arrangement, one of them bearing marks (50) 0 to 9 that form the units of the dates and the other bearing marks (40) 0 to 3 forming the tens, these being arranged in such a way that the respective marks (40, 50) are juxtaposed to indicate the day of the month (70), characterized in that said marks (40, 50) are arranged non uniformly, so that the angular separation formed between the start of one mark (40, 50) and the start of the next mark (40, 50) varies from one mark to another, the marks (50) 0 to 9 forming the units being separated by an angle which varies from around 33° between the marks 0 and 1 to around 38.5° between the marks 2 and 1, the marks (40) 0 to 3 forming the tens being duplicated (0, 0; 1, 1; 2, 2; 3, 3) and being separated by an angle that varies from around 41° between the marks 1 and 0 up to around 48° between the marks 2 and 1. The timepiece further comprises a mechanism for driving said discs and/or rings (20, 30) in uniform angular steps of around 36° per day in the case of the disc/ring (30) bearing the marks (50) forming the units and around 45° every five days in the case of the disc/ring (20) bearing the marks (40) forming the tens.
