Dievas is following up the original Vortex with this Vortex Professional. I always liked the original Vortex. It more or less combined the best features of a dive watch with the best features of an aviator watch. For many people, this is the ultimate "mission" timepiece.
Two years after the original Vortex was released the Professional seeks to improve upon the tool-like nature and legibility of the watch. I think that for many people the original Vortex is going to be more of a "style" watch, but the Professional is just that - for more serious situations where durability and legibility are essential.
The Professional has a 44mm wide grade 5 titanium case coated in black DLC - which is very scratch resistant. It still has the rotating diver's style bezel and the good-looking case design. The watch is water resistant to 500 meters with a sapphire crystal. It also has an automatic helium escape valve. The dial is now all lume with the numerals and hands being in black. For style the triangle 12 o'clock hour indicator is large and in red. That little dash of color is nice. Dials such as this are incredible at night as there is so much lume and it frames the black segments perfectly. The lume is all SuperLumiNova. If you can't read this dial, you likely have someone reading this article to you out loud.
Inside the Vortex Professional is a Swiss ETA 2824-2 automatic movement. The black case is done in a sandblasted finish before the DLC coating so it has a smooth, matte finish to it overall. As you can see, Dievas is offering the watch with a black water-resistant treated calf leather strap with either black or red contrast stitching. Price is a very reasonable $1,130 and you can get one here.
