The Sinn 613 St 613.012 is an incredible Made in Germany diving chronograph.

The watch is stylish and extremely legible. Every element has a great mix of the iconic design with practicality and functionality added in. When you wear this watch it will stand out in a discreet manner showing the right mix of popping white elements and natural colours, without falling for the tendency of watch manufacturers to overdo things. 

Another real gem is in the technical elements of the watch as those are absolutely top notch. This is a well balanced, comfortable watch due to the crown at 3, very comfortable steel bracelet and fully bead blasted high quality steel case. But it's also a very serious watch with 500m water resistance (DNV certified) as well as Ar-Dehumidifying Technology which enhances functional reliability and freedom from fogging. Under the hood is the SW 515, this is an amazing chronograph movement with a 60 minute stopwatch display at 6 o'clock (and the active seconds at 9 o'clock). 

The 613 St is versatile, it's practical, it's breathtaking, it's quite simply one of the most unique diving watches out there.
