The first thing we look at is the Pilot. There are Chronographs but also conventional manual and automatic models. There are models with bidirectional rotating bezel for measuring intermediate times (eg. Tutima or Hanhart) or without rotating bezel. There are navigational watches Longines Lindbergh or Longines Weems which can be used for the calculation of the positions. Another important feature is protection against magnetism. Moon watch, Omega Speedmaster, is a well-known pilot watch.
Well-known pilot watches are:
- Breitling Navitimer
- Omega Speedmaster Professional
- IWC Big Pilot
- Citizen Nighthawk
A Diving Bell, also known as a diver or dykklocka is a watch designed for underwater diving that has at least one water resistance greater than 1.0 MPa (10 atm), the equivalent of 100 m (330 ft). Example is the Breitling Avenger Seawolf which is water resistant down to 3000 meters or 10,000 feet. Even Rolex Submariner is a renowned divers.
Famous divers are:
- Citizen Eco-Zilla
- Rolex Submariner
- Omega Seamaster Professional
- Omega Seamaster Planet Ocean
- Seiko Orange Monster
- Seiko Marine Master
Sports watches has no clear definition in the same way as a Pilot or scuba divers. However, it should be equipped with a chronograph for timing. Sport is a card that comes from old French and actually means casual or casual. It is not about a clock you have when you do sports without a watch you can wear everyday.
The difference between the three
Sometimes no distinction is made on the sport and Diving Bell. So the border is a bit fuzzy. There are also other types of watches, as military and dressed up clock.
A dressy watch is possibly something that brings to mind a Daniel Wellington-watch or the theeliteswatches. A clock that works great for certain occasions. But if you buy an expensive watch, you should bet on any Classic instead. A dressy watch can many times be attributed to what is meant by Fashion-watches. That is to say, watches that get their looks depending on what is trendy right now. Not very timeless, that is.
Regarding military watches, we are once again back to the three classical categories above. Often we mean watches worn by the U.S. military. They in turn classifies them as diving watches and clocks.
A Diving Bell most characteristic trait is its rotating bezel, the ring surrounding the watch face (bezel). Typical is that it rotates counterclockwise (safety precaution). It works so that if a diver has 10 minutes of oxygen left, and time is 14:00, he will rotate the arrow mark (pip) so it is flush with the minute hand. When the minute hand is then in line with the number 10 on the bezel the diver must begin their ascent in order not to be without oxygen.
Regarding a pilot watch bezel helps you to do arithmetic or conversions in the air. A transformation can be, for example, between a mile and kilometre. Or if you need r count how much fuel you have in the tank.
It is not uncommon to find the chronograph on a pilot’s watch. Or the function to see the time in other parts of the world (you fly the thought everything).
