Casio Wave Ceptor
The Wave Ceptor series (stylized as WAVE CEPTOR or WaveCeptor) is a line of radio-controlled watches by Casio. Wave Ceptor watches synchronise with radio time signals broadcast by various government time services around the world. These signals transmit the time measured by atomic clocks accurate to one second in millions of years. By synchronizing daily with the signals, the Wave Ceptor watches achieve high accuracy, using a quartz crystal to keep time in the interim. Some radio watches, including some Wave Ceptors, are solar-powered, supported by a rechargeable battery. The watch displays may be fully digital, analog, or analog-digital. Hybrid Wave Ceptor models support GPS satellite reception of both time and location, in addition to broadcast signals. Radio-controlled watches require no setting of time, date, or daylight saving time adjustments, as they attempt automatic synchronization several times every night. Without synchronisation, Wave Ceptors, like other commercial qu ...

Shangqiu
Shangqiu (), alternately romanized as Shangkiu, is a city in eastern Henan province, Central China. It borders Kaifeng to the northwest, Zhoukou to the southwest, and the provinces of Shandong and Anhui to the northeast and southeast respectively. Its population was 7,816,831 inhabitants as of the 2020 Chinese census whom 2,831,814 lived in the built-up (''or metro'') area made up of two urban districts (Liangyuan and Suiyang) and Yucheng county now being conurbated. Shangqiu and surrounding area was an important base for the Shang dynasty (c. 1600 – c. 1046 BC), and the city itself was established more than three millennia ago. Shangqiu has grown significantly in recent years. It is located at an important location at the junction of several major railways, making it a major regional transportation hub.

Junghans
Junghans Uhren GmbH is a German watch and clock manufacturer. The company is located in the district of Rottweil, in a town called Schramberg, Baden-Württemberg, southwest Germany. History On 15 April 1861 Erhard Junghans created the company ''Junghans und Tobler'' together with his brother-in-law Jakob Zeller-Tobler in Schramberg. By the year 1903, Junghans had the largest watch and clock factory, with over 3000 employees. The company began to produce wristwatches in 1927, and over the following decades created clocks and watches for the civilian market and the German air force. Beginning in the 1950s, the Bauhaus-trained designer Max Bill created products for the firm, notably the teardrop-shaped "Kitchen Clock with Timer", which can be found in the collection of The Museum of Modern Art, and followed by a series of watches, the first of which launched in 1961. The relationship between Junghans and Bill lasted many years, and the company has continued to release new models ...

Citizen Watch Co
Citizenship is a "relationship between an individual and a state to which the individual owes allegiance and in turn is entitled to its protection". Each state determines the conditions under which it will recognize persons as its citizens, and the conditions under which that status will be withdrawn. Recognition by a state as a citizen generally carries with it recognition of civil, political, and social rights which are not afforded to non-citizens. In general, the basic rights normally regarded as arising from citizenship are the right to a passport, the right to leave and return to the country/ies of citizenship, the right to live in that country, and to work there. Some countries permit their citizens to have multiple citizenships, while others insist on exclusive allegiance. Determining factors A person can be recognized or granted citizenship on a number of bases. Usually, citizenship based on circumstances of birth is automatic, but an application may be required. ...

G-Shock
The G-Shock is a line of watches manufactured by the Japanese electronics company Casio, designed to resist mechanical stress, shock and vibration. G-Shock is an abbreviation for ''Gravitational Shock''. The watches in the G-Shock line are designed primarily for sports, military and outdoors-oriented activities; all G-Shocks have a chronograph feature, 200 metre water resistance and an alarm, with either a digital display, analogue display or a combination of analogue and digital displays. Other features such as a countdown timer, world clock, and a backlight are included in most models. Newer high-end models in the line also feature GPS, directional, pressure and temperature sensors, radio-controlled time adjustment (known as WaveCeptor or Multi-Band) and Bluetooth time adjustment achieved via connecting to a smartphone via a dedicated application. History The G-Shock was conceptualised in 1981 by Casio engineer Kikuo Ibe when he accidentally dropped and broke a pocket watc ...

Mainflingen
Mainflingen is a village and part (''Ortsteil'') of the municipality Mainhausen, in the district of Offenbach in Hesse with about 4000 inhabitants. It is known for its time signal transmitter, DCF77, which controls almost all radio clocks in Western Europe. Geography Location Mainflingen is part of the municipality Mainhausen, which lies in the Offenbach district, located in the southernmost part of the state Hesse right on the border with Bavaria. It lies near the river Main. Constituent communities Mainflingen is one of the two constituent communities of Mainhausen, the other one is Zellhausen.

DCF77
DCF77 is a German longwave time signal and standard-frequency radio station. It started service as a standard-frequency station on 1 January 1959. In June 1973 date and time information was added. Its primary and backup transmitter are located at in Mainflingen, about 25 km south-east of Frankfurt am Main, Germany. The transmitter generates a nominal power of 50 kW, of which about 30 to 35 kW can be radiated via a T-antenna. DCF77 is controlled by the ''Physikalisch-Technische Bundesanstalt'' (PTB), Germany's national physics laboratory and transmits in continuous operation (24 hours). It is operated by ''Media Broadcast GmbH'' (previously a subsidiary of ''Deutsche Telekom AG''), on behalf of the PTB. With Media Broadcast GmbH, a temporal transmission availability of at least 99.7% per year or under 26.28 hours of annual downtime has been agreed upon. Most service interruptions are short-term disconnections of under two minutes. Longer lasting transmission servi ...

Anthorn Radio Station
Anthorn Radio Station is a naval and government radio transmitting station located near Anthorn, Cumbria, England, overlooking the Solway Firth, and is operated by Babcock International (with whom former operators VT Communications are now merged). It has three transmitters: one VLF; one LF; and an eLORAN transmitter. It is on the site of the World War II military airfield which was operated by the Fleet Air Arm as HMS ''Nuthatch''.

Time From NPL
The Time from NPL is a radio signal broadcast from the Anthorn Radio Station near Anthorn, Cumbria, which serves as the United Kingdom's national time reference. The time signal is derived from three atomic clocks installed at the transmitter site, and is based on time standards maintained by the UK's National Physical Laboratory (NPL) in Teddington. The service is provided by Babcock International (which acquired former providers VT Communications), under contract to the NPL. It was funded by the former Department for Business, Innovation and Skills; NPL Management Limited (NPLML) was owned by the Department for Business, Energy and Industrial Strategy (BEIS), and NPL operated as a public corporation. The signal, also known as the MSF signal (and formerly the Rugby clock), is broadcast at a highly accurate frequency of 60 kHz and can be received throughout the UK, and in much of northern and western Europe. The signal's carrier frequency is maintained at 60 kHz to wit ...

Fort Collins
A fortification is a military construction or building designed for the defense of territories in warfare, and is also used to establish rule in a region during peacetime. The term is derived from Latin ''fortis'' ("strong") and ''facere'' ("to make"). From very early history to modern times, defensive walls have often been necessary for cities to survive in an ever-changing world of invasion and conquest. Some settlements in the Indus Valley civilization were the first small cities to be fortified. In ancient Greece, large stone walls had been built in Mycenaean Greece, such as the ancient site of Mycenae (famous for the huge stone blocks of its 'cyclopean' walls). A Greek '' phrourion'' was a fortified collection of buildings used as a military garrison, and is the equivalent of the Roman castellum or English fortress. These constructions mainly served the purpose of a watch tower, to guard certain roads, passes, and borders. Though smaller than a real fortress, they acte ...
