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.

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)::

Eine wunderbare Uhr. Ich besitze bereits mehrere Versionen dieses zuverlässigen Solarchronos und bei dieser Save The Oceans-Edition konnte ich einfach nicht widerstehen. Sehr robust, absolut wasserdicht und gut ablesbar. Allerdings nichts für zierliche Handgelenke. Die Uhr ist trotz ihrer Größe noch angenehm leicht zu tragen.
