A horology calendar system (100; 200) comprising: a date display member (10) including an opening (10a); and a month display member (30) arranged in such a way as to display an indication of the month in the opening (10a), notably when the opening (10a) is visible to a user of the calendar system and/or when the calendar system is indicating the first day of a given month.

A display device includes a solar panel and a display board. The solar panel includes power generators and a connection area which connects the power generators, and which generates a smaller amount of power than the power generates generate. The connection area is a linear narrow area narrower than the power generators. The display board includes highly transparent areas having high optical transparency, and a less transparent area having lower optical transparency than the highly transparent areas have. The highly transparent areas are disposed to overlap with each area where the power generators are disposed and not to overlap with an area where the connection area is disposed, and the less transparent area is disposed to overlap with an area where the connection area is disposed.

Disclosed is an electronic device, including: a base including: a first mounting part that includes a main surface provided in an annular shape; a second mounting part that is provided at an inner side of the first mounting part and includes a main surface and a raised part raised upward; and a third mounting part that is provided around the first mounting part; and an annular calendar disk that has a thickness smaller than a difference between a height of the raised part of the second mounting part and a height of the main surface of the third mounting part and includes an inner peripheral side partly disposed on the second mounting part. The main surface of the second mounting part and the raised part are both lower than a main surface of the third mounting part and higher than the main surface of the first mounting part.

A module includes a plate and a sheet-like component. The sheet-like component is a first sheet-like component or a second sheet-like component and is fixed to the plate by an adhesive. The plate has a first marker and a second marker. The first marker indicates an adhesion position of a first adhesive for the first sheet-like component to be fixed to the plate. The second marker indicates an adhesion position of a second adhesive for the second sheet-like component to be fixed to the plate.

An electronic timepiece has a case made at least in part from a conductive material and including a main case member and back cover and; a drive module disposed inside the case for displaying the time; a GPS antenna disposed inside the case around the drive module; and a crystal made from a non-conductive material and disposed to the opposite side of the case as the back cover. The GPS antenna is superimposed with the crystal in plan view, and not superimposed with parts of the main case on the crystal side of the GPS antenna.
