By TLex This is the Zlatoust 193-ChS, a scaled down and slightly updated automatic, 53mm version of the legendary 191-ChS 'Vodolaz' diver that traces its roots back to the late 1950s and 60s, when it was supplied to almost every USSR Navy (ВМФ СССР) diver, who wore one as part of their diving equipment, despite its application of radioactive lume!
Some decades later, the 191-ChS was re-issued as the 192-ChS, which was produced without the harmful radioactive material. However despite this, it still remained an enormous 60mm in diameter, making it almost impossible for anyone to wear, apart from Arnold Schwarzenegger (the man, who in many ways was responsible for bringing it into the limelight)!
This meant that despite its extraordinary heritage, the 'Vodolaz' dive watch could not easily (if at all) be worn by enthusiasts; not until a Russian military watch expert collaborated with the AGAT Clock Factory in Province of Chelyabinsk, Russia - to re-design a new automatic 53mm version of the watch, the ChS-193.
Not only scaled down 53mm case, but the ChS-193 also has a much more comfortable left-handed crown placement plus a couple of cosmetic enhancements, such as a new handset and 'Agat' factory logo (12 o'clock) and 'Russia' text (6 o'clock). It has even been fitted with spring bars, so that it can be easily worn on third party straps.
The ChS-193 houses a Vostok 2415 automatic mechanical movement, which replaces the original hand wound 2409. Apart from this and the above, it is the same 700m fixed bezel Russian dive watch that has been hand -crafted in Russia in the exact same manner that other 'Vodolaz' have been since the late 50s. It looks the same and feels the same, but can actually be worn relativity comfortably on the wrist, and without risk of your teeth glowing in the dark!
The ChS-193 is still available, but in very limited supply. I don't know of anyone, who has these watches outside of Russia apart from the same Russian Military watch expert, who co-designed it with the AGAT factory, who I acquired mine from.
