An electronic watch includes a power generating mechanism; a battery that is charged with power generated by the power generating mechanism; hands that include a second hand; a driving source that rotates the hands; a driving circuit that drives the driving source with power supplied by the battery; and a control circuit that controls the driving circuit. The control circuit executes a first stopping operation for stopping the driving circuit and the control circuit in a power saving mode for suppressing power consumption and when a first determination time elapses without any power being generated by the power generating mechanism. The control circuit executes a second stopping operation for stopping the driving circuit and the control circuit in the power saving mode and when a second determination time elapses while a voltage of the battery is at a level equal to or lower than a predetermined level.

A semi-transparent photovoltaic module made up of a plurality of photovoltaic cells that are electrically connected in series, said cells being composed of active photovoltaic regions (2) contained in annuli referred to as active annuli, said active photovoltaic regions of a given active annulus being separated by insulating regions (4); and of vacant space (3) that forms transparent regions in transparent annuli; two adjacent annuli being separated by one transparent annulus (3) and two active photovoltaic regions (2) of adjacent active annuli belonging to the same cell being connected by at least one conductive bridge interconnect (8). Said module is characterized in that adjacent insulating regions (4) do not face each other.

In a timepiece, moments of inertia of a first pointer and a second pointer that are for displaying first information and second information, respectively and that have a same rotation axis are the same. As a result, parts having identical specifications may be used in a drive mechanism of the first pointer and a drive mechanism of the second pointer. Further, color schemes of the first pointer and second pointer differ. As a result, a user may easily distinguish the first pointer and the second pointer.

An electronic timepiece includes: a measurement result obtaining section configured to obtain a measurement result of a display target item which is any measurement item among a plurality of measurement items; a display configured to display the measurement result of the display target item; and a display controller configured to cause the display to display the measurement result of the display target item during a display period that corresponds to the display target item, in which the display period is set in accordance with each of the plurality of measurement items.

A watch includes a power reserve hand configured to be visually recognizable from a watch rear side, an oscillating weight including a weight, a transmission wheel configured to rotate a ratchet wheel, a pawl lever configured to engage with the transmission wheel, an eccentric wheel including an eccentric shaft member to which the pawl lever is attached and an eccentric toothed gear, a train wheel bridge provided between the pawl lever and the oscillating weight, and a seconds wheel and pinion including a seconds hand shaft. The eccentric shaft member and the seconds hand shaft are supported by the train wheel bridge. The power reserve hand is disposed in a position that does not overlap the weight in plan view, and is disposed in a position that overlaps the train wheel bridge in side view orthogonal to the seconds hand shaft.
