Discussed are a smart watch and a control method for the same, which provide a notification indicating events, which are scheduled to occur later on the basis of a take-off time, if the smart watch is taken off. The smart watch includes a display unit to display content, a communication unit to perform transmission/reception of data, and a sensor unit to detect an input signal with regard to the smart watch and transmit the signal to a processor that serves to control the aforementioned units. The processor detects a take-off signal, indicating separation of the smart watch from a user, in a worn mode, to switch the smart watch to an unworn mode in response to the detected take-off signal, and provides a notification indicating at least one event that is scheduled to occur after detecting the take-off signal in the unworn mode.



Timepiece movement with a tourbillon fitted with a shock protection device

Tue, 24 Mar 2015 08:00:00 EDT

A timepiece movement including a tourbillon that has a rotating carriage bearing a sprung balance and an escapement. The carriage includes a top pivot and a bottom pivot, respectively carried by a top bridge and a bottom bridge of the carriage. The carriage pivots between a bottom plate of the timepiece movement and a bridge of the movement in the timepiece movement includes a stop member, arranged for limiting the axial shake of the carriage.



Change of state indicator for a jump display mechanism

Tue, 17 Mar 2015 08:00:00 EDT

A change of state indicator (2) device for a timepiece display mechanism (30) by jumps of a given magnitude for the display of a transition between two stable display states of this given magnitude movable close to the display zone of this magnitude facing a supplementary display (3) driven discontinuously by a drive element (7) against elastic return means (19). A driving pinion (9) controls a star wheel (10) in a discontinuous manner to control each jump against a beak (14) of a first arm (15) of a lever (13) controlling a pivoting movement and a return to position of this indicator (2) each time this beak (14) passes between two successive tooth spaces (12) of this star wheel (10) by means of a tooth (11) between these spaces (12). The lever (13) includes a second support arm (16) for supporting the indicator (2) or controlling its displacement.



Golfing accessory time piece

Tue, 17 Mar 2015 08:00:00 EDT

A golfing time-keeping apparatus is arranged to indicate time of day using a clock face and a movement which has at least a minute hand arranged to complete a revolution of the clock face every hour. The time piece includes a structure for indicating a plurality of subdivisions of a time period longer than 1 hour and shorter than 5 hours, the structure comprising an indicator having a plurality of markings arranged for general visual alignment with the minute hand. The markings include a sequence of indicia circumferentially spaced apart and continuing for more than one but no more than five revolutions wherein some of the later indicia in the sequence are interleaved with some of the earlier indicia.



Power supply unit and electronic timepiece

Tue, 17 Mar 2015 08:00:00 EDT

A power supply unit has a first power supply circuit that supplies a voltage to a load driving unit and a second power supply circuit that supplies a voltage to circuits other than the load driving unit. A first switching unit connects any one of a power supply that supplies a power supply voltage and a voltage step-down circuit that supplies a step-down voltage of the power supply voltage to the first power supply circuit. A second switching unit connects any one of the power supply and the voltage step-down circuit to the second power supply circuit. A control unit controls the connection by the first switching unit and the connection by the second switching unit to switch the voltage supplied to the first power supply circuit and the voltage supplied to the second power supply circuit in accordance with properties of the load driving unit.
