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…
If you consider that divers rely on a good watch in order not to die, one could expect designated divers watches to be quite robust timepieces. In Germany, where we are based, a divers watch has to fulfill certain criteria before being allowed to be called a divers watch. These watches are usually watertight to a pressure of 20 bar and over. They are also fitted with large indexes and fingers so that they are easy to read through your goggles in the dim light of the deep blue sea at a distance of at least 25 cm. They will also have to have a timer or a bezel which can be turned to indicate the time a diver needs to consider when calculating the remaining oxygen in his or her tank and to keep the intervals needed when ascending back to the surface. This bezel can only be turned one way so as to eliminate the possibility of it being moved by accident, increasing the diving time over the oxygen supply and thus causing a horrible death through drowning.
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
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):
FYI: 10m is 1 bar is (roughly) 33 ft is (exactly) 0.986923267 atm

Traumhaft schöne Certina mit auffälliger Farbe der Lünette (Geschmacksache freilich - aber für mich sehr schön und mal was anderes). Preis-Leistung top! Den ersten Kroatienurlaub mit reichlich Meerwasser- und Sandkontakt hat die Certina tadellos gemeistert, keine Kratzer.

Aufgrund meines eher kräftigen Armumfanges benötigte ich ein Extraglied fürs Armband, welches mir von Uhrzeit.org kostenlos und in schnellster Zeit geliefert wurde.
Somit Uhr und Händler meinerseits bestens zu empfehlen!
Eine sehr schöne Uhr, welche toll verarbeitet ist und gut am Handgelenk liegt. Nicht zu groß und nicht zu klein. Das Edelstahlarmband hat massive Bandanstöße! Sehr ganggenau. Einziger Wehrmutstropfen: Bei meiner Uhr steht der große Sekundenzeiger zwischen 59 und Null, also nicht exakt mittig. Daher leider ein Stern Abzug.
J,I bought a Certina on 14,03.17send the same Day from Germany, received at my home 18,03,17.Iam very satisfied with the watch,the price and the service.Really à very professional,which I highly recommend Juan
Wirklich eine Top Uhr von mir nur zu empfehlen. Stabil sieht gut aus. Das orange ist in live viel schöner als auf den Bildern. Abwicklung, Lieferung alles ohne Probleme. Kann man nur weiterempfehlen.
Wunderschöne Uhr...bin schon einige Male drauf angesprochen worden. Gerade die Variante in der Farbe Orange hat das gewisse etwas. Perfekte Certina Qualität. Lieferung in einem sehr schönen Kasten in dem die Uhr auch weiterhin ein sicheres Lager findet. Würde Sie jederzeit wieder kaufen.
