A timepiece sub-assembly includes, irreversibly fixed to a main plate and each irreversibly pre-adjusted by the irreversible securing of adjustment and/or assembly components, after the particular timepiece function thereof has been adjusted and function checked on the test bench, functional modules including a gear train module, a display module, and a time-setting module. Other mechanical sub-assemblies, each irreversibly fixed to the preceding lower order mechanical sub-assembly, include various modules including motor module, frame-mounted self-winding device module, escapement holder regulating module, motion work train, date module, and self-winding module. A mechanical movement including at least one mechanical sub-assembly of this type and a watch including a mechanical movement of this type are also disclosed. A method of assembling mechanical sub-assemblies of this type by the irreversible securing of mechanical sub-assemblies and irreversibly pre-adjusted modules is also disclosed.

An electronic timepiece includes a second hand, a dial having a display area provided with a plurality of markings corresponding to the second hand, and a display controller that controls driving operation of the second hand to cause the second hand to display calendar information. The display area, when viewed from a timepiece front side, is divided by two straight lines that pass through a rotating shaft of the second hand and are perpendicular to each other into four divided areas. Each of the divided areas is related to years elapsed since a leap year, and each of the markings is related to the month. The display controller, when causing the second hand to display the calendar information, causes the second hand to point at one of the markings in one of the four divided areas to display the elapsed years and the month.

A perpetual calendar for a watch including a movement controlling the daily release, at the moment that the date changes, of a mechanism actuating a perpetual lever of this perpetual calendar is disclosed. The perpetual calendar includes a calendar mechanism, a daily countdown mechanism including a month-end adjustment mechanism, and a differential mechanism. The calendar mechanism is arranged to determine the duration of the current month and is updated at each current month change by the daily countdown mechanism. The differential mechanism is arranged to control, each day at the moment that the date changes, the motion of an additional adjustment cam comprised in the month-end adjustment mechanism, based on the current day of the month taken from the daily countdown mechanism, and also based on the current month duration taken from the calendar mechanism.

The present invention relates to a timepiece comprising a frame and a device (1) for displaying the equation of time. The device (1) for displaying the equation of time comprises a first support (2) and a second support which are superposed, or, respectively, mounted so as to be able to rotate with respect to the frame, the first support (2) bearing a curve (6) that represents the equation of time, and the second support bearing a pointer (12) arranged such that the intersection of the pointer (12) with the curve (6) is visible, and means for driving the first (2) and second supports that are arranged such that the first (2) and second supports rotate at respective speeds that allow the value of the equation of time to be displayed at the intersection of the pointer (12) with the curve (6).

The invention concerns a grand date display device that can change from displaying the last day of the month to displaying the first day of the following month by means of a single step of the first and of the second upper plates. This feature avoids the requirement for a correction at the end of months of less than 31 days.

An electronic timepiece has a base plate made from a non-conductive material, and a planar antenna disposed on the back side of the base plate. The planar antenna has a dielectric substrate and an antenna electrode disposed to the base plate side of the dielectric substrate. An exposed area not superimposed with the antenna electrode 42 is formed on the surface of the dielectric substrate. The base plate has a through-hole overlapping at least part of the antenna electrode in plan view, and a cover part overlapping at least part of the exposed surface in plan view.

A timepiece with date display comprises two supports (20, 30), for example superposed discs or rings, each bearing a set of signs (40, 50) according to an annular arrangement, one bearing signs (50) 0 to 9 forming the date digits and the other bearing signs (40) 0 to 3 forming the decimals, arranged in such a manner that the respective signs (40, 50) are juxtaposed in order to indicate the date (70), characterized by the fact that said signs (40, 50) are disposed in a non uniform manner, such that the angular deviation formed between the start of a sign (40, 50) and the start of the following sign (40, 50) varies from one sign to another, the signs (50) 0 to 9 forming the digits being separated at an angle varying by around 33° between the signs 0 and 1 to around 38.5° between the signs 2 and 1, the signs (40) 0 to 3 forming the decimals being doubled, (0, 0; 1, 1; 2, 2; 3, 3) and being separated at an angle varying by around 41° between the signs 1 and 0 to around 48° between the signs 2 and 1. The timepiece further comprises a mechanism for driving said discs and/or rings (20, 30) by uniform angular pitches of around 36° per day for the disc/ring (30) bearing the signs (50) forming the digits and of around 45° per five days for the disc/ring (20) bearing the signs (40) forming the decimals.

The invention concerns a timepiece that has a single hand, which is movable into a plurality of hand positions. The timepiece has a clockwork for mechanically moving the hand so that the hand is located in a hand position which corresponds to a current time of day and an actuating element connected to the clockwork. The clockwork is designed to change, upon actuation of the actuating element, from a first operating state into a second operating state and to move the hand so that the hand position in the first operating state displays minute information and in the second operating state displays hour information.
