One of the four basic categories of Victorinox Swiss Army Watches, named Professional, consists of four subsections. These sub-series are named Air Boss, Alpnach, Dive Master 500 and ChronoPro. Let us present the traits of each of these lineages that together make the Professional series.
Timepieces with the Air Boss designation may look similar, but are actually quite different. All of them are round-shaped, with anti-reflective sapphire glasses and stainless steel cases. However, at the core, they are quite dissimilar. Some are made with various mechanical self-winding movements, while others have quartz mechanisms. These timepieces can be with chronographs and countdown timers.
The second sub-section of Proffesional Watches is named Alpnach. These timers are powerful chronographs with automatic movements, glare-proof sapphire crystals, rotating bezels and crown protection. Their cases are also circular and made of steel, and paired with leather straps.
Colorful Dive Master 500 timepieces form Professional category of Swiss Army Watches are made to be suitable for diving, and as their name suggest, they allow water resistance to 500 meters. Other convenient features that make them useful under the surface are unidirectional bezels, EOL indicators and rubber straps. All of them are quartz-driven.
The final sub-category in the section, named ChronoPro, currently offers just a single timepiece. The watch in question is a mechanical chronograph. As all previous models, it is also round and protected with sapphire glass.
