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…

The most robust watch crystals are made out of sapphire glass. Only diamonds and carbide is harder and can scratch sapphire glass. Of course there are other materials such as some metals and stones which will scratch your sapphire glass crystal, so it is not wise to expect the watch to handle any abuse without getting marked. Sapphire has one downside though, it is highly reflective. Some watches receive an anti-glare coating to compensate for this, but sadly this coating is less hard and will scratch more easily.glass
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./ World time
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)::

Super Uhr, bin ich sehr zufrieden mit und kann sie sehr empfehlen! Die Uhr läuft sehr genau, ist ja auch batteriebetrieben. Die angegebene Größe ist ohne Krone, mit Krone ist sie locker 4,5cm groß. Das Armband besteht aus Kautschuk, wirkt optisch aber stark wie ein lederarmband, was auch an der Ziernaht liegt. Der Chronograph misst Zeiten bis zu einer halben Stunde mit den üblichen Funktionen. Die Zeiger haben eine breite Leuchtmasse und die Indizes leuchten durch kleine Punkte. Eine Datumsanzeige wurde auf der 6 Uhr Position beigefügt und die Uhr ist auch noch bis zu 10 bar (100m) wasserdicht. Das Glas ist sehr kratzfest und entspiegelt (Saphirglas).
Schon zweimal defekt gewesen.
