General
Typ: Chronograph
A chronograph is a stop watch. Most wristwatches that incorporate a stop watch are also called chronographs, but this is just because it sounds more fashionable, in reality they are still wrist watches that incorporate a chronograph. The word chronograph comes from the ancient Greek word “chronos”, meaning time and “graphein”, to write. So in effect it’s a time-writer. Chronographs are not to be mixed up with chronometers. They are something completely different, which will be explained in the bit about…

Radiocontrol
Radio controlled watches and clocks are timepieces that are able to receive a radio transmitted time signal and set themselves to it. They are what you and me can use to benefit from these incredibly exact atomic clocks out there. There are many different time signals, most countries have their own, so lets get technical: There is the MSF signal, also known as “Rugby Clock”, which broadcasts at a frequency of 60 kHz from the Anthorn radio station in Cumbria at a signal strength of 17 kW. The effective range is approx. 1000 km, so it will be received throughout the UK and western Europe. There are three atomic clocks on site, operated by the National Physical Laboratory. The information in the signal includes the UTC (former GMT) year, month, day of month, day of week, hour, minute, British Summer Time. The other commonly used radio time signal broadcast in Europe is the DCF77. This is broadcast from Mainflingen, near Frankfurt/Germany. So it is placed pretty centrally in Europe. It is transmitted at 77.5 kHz with a relatively high power of 50 kW, which means it has an effective range of 2000+ km. The signal contains pretty much the same information that the UK MSF signal does, but in UTC+1 (or CET). It is widely used in Europe because of its strength and centrally located broadcasting station. It is also quite popular in the UK, as almost all radio controlled watches can be set to a different time zone. This means they will still receive the DCF77 signal, but then add or subtract the amount of hours according to which time zone they have been set to.
There are multi-frequency watches available. These watches will be able to receive different time signals on different frequencies. Apart from the UK’s MSF and the European DCF77, the most common ones are the US WWVB (60 kHz) and the Japanese JJY (40 kHz and 60 kHz).
It is very important to know that the radio signal and the reception thereof is subject to various conditions. Apart from the fact that the signal does not mix that well with thick concrete and steel buildings, the time of day and the weather play a huge role. Rain will lower the range, but the signal will bounce off clouds, amplifying it a bit. The signal can travel further at nights and even the time of year and the position of the moon can have a slight impact. It has happened, that radio controlled clocks in eastern Canada set themselves regularly to the German DFC77 signal. It can also happen that you will have problems receiving the signal in the middle of England. Most commonly it is a too weak battery, but you could live in a valley or behind a mountain or just a massive building. If you are having problems receiving a radio signal, place it on the windowsill over night, preferably in the direction of the broadcasting station which signal you are trying to receive. If this does not work, turning the watch by 45° might do the trick. Sounds like a lot of witchcraft? Well, radio controlled watches are a lot more technical and tricky than normal ones. A perfect every-day reception is by no way guaranteed by the manufacturers. And it is not really required as the watches only use the signal to set their highly accurate quartz movements. Unless you calculate time in milliseconds, a couple of days without a signal will pass unnoticed.

Time zones
Since the going theory stipulates that the earth is not flat and the sun is not the sun-god Ra in his golden chariot, but that we actually live on a ball of dirt flying around a star, it is obvious that the daytime will never be the same on any two points of different longitude at any given time. Now if you were going to be precise, then you are actually in a different time of day than your neighbours to the east and west of you. But that would be splitting hairs, or would it? Anyways, important people decided a long time ago that for practicalities sake, they would divide the globe into 24 time zones that are one hour apart. Of course one had to find a compromise between geographical position and national borders in order for ordinary life to function. Since the industrial revolution, people adhering to the same principles of time measurement have become essential to the workings of our society. But you will find that every so often a time zone will shift in order to make life easier or more profitable in one country or region. For example the UK is considering not of moving to a different time zone, that would be rubbish of course, since they invented it, but of adopting “double summer time” in one year and then only going back one hour at the end of it. This would effectively put them in the same time zone as the rest of Europe.

Waterproof
Water tightness or impermeability, surprisingly enough, is the degree to which you can expose your watch to the element water. A watch can be water repellent to a variety of degrees, from surviving the odd splash, to keeping the watch fully functioning long after your crushed body has hit the ocean floor. Please note that these are always theoretical values. Water behaves very differently at different temperatures and with varying salinity. So we took our crayons and made you this rough guide (which, by the way, is in no way legally binding and we will not be held accountable for your watch if you ruin it):

Waterproof

Eine tolle Uhr mit vielen Möglichkeiten. Die Uhr liegt gut am Handgelenk und ist ein Blickfang. Das Beste an der Uhr ist, dass sich die Uhr selbst durch den Funk einstellt und dadurch immer genau ist.

Super Kaufabwicklung von der Bestellung bis zur Lieferung. Wer nicht gleich komplett bezahlen kann oder will, nimmt die Zahlungsart "Ratenzahlung". Alles erklärt und bei Hilfe bekommt man kompetente Ansprechpartner. Artikel kam in einwandfreien Zustand an. Sehr schöne Uhr mit vielen raffinierten Kleinigkeiten,so wie man es von Citizen kennt. Der Beschenkte hat sich rießig gefreut. Würde jederzeit wieder bestellen.

Die Uhr besticht durch eine starkes Aussehen, sehr schöne Fliegeroptik, die Uhr hebt sich deutlich von anderen Uhren ab. Die Materialien wirken hochwertig und zeugen für die Langlebigkeit der Uhr. Sie funktioniert sehr präzise, wegen der Funktechnik. Eine solarbetriebene Uhr ist einfach am Besten. Kein Batteriewechsel im Geschäft oder irgendwelches Aufziehen oder Rumgeschüttel, wie bei einer mechanischen Uhr. Das Saphirglas ist sehr gut und sehr kratzfest. Datums- und Wochentagsanzeige waren ein absolutes Muss und sind natürlich vorhanden, genau wie eine Stoppuhr und leuchtende Zeiger und Indizes. Die Uhr stellt sich in einer anderen Zeitzone automatisch um. Einfach nur klasse. An das Lederarmband musste ich mich anfangs gewöhnen, da ich bisher immer Armbänder aus Edelstahl hatte, aber das ging schnell.
Hervorragende Uhr zum annehmbaren Preis. Würde die Uhr wieder kaufen!

Ich habe die Uhr seit einem Monat. Sie ist wirklich toll, entspricht absolut der Beschreibung. Ich kann die Uhr nur weiterempfehlen.
An das Lederarmband muß ich mich noch gewöhnen, da ich bisher nur Edelstahlarmbänder hatte.
