The Chkalov 3602.16 is a Russian made mechanical handwinding Regulator watch. Chkalov watches use a new Molniya 3602 mechanism, which was released in the USSR, but updated and maintained by a modern manufacturer. This is a unique case, when a small batch of pristine mechanisms lay in the warehouse for decades and were given a new lease of life. Some of the improvements in the mechanism are worth noting, such as hand-ground screws and wheels, serviced and tuned with modern technology. The stainless steel case has a 41mm diameter and a thickness of 12mm. Underneath the domed sapphire crystal with anti-reflective coating, there is a structured dial with superluminova numerals. The crown of the watch features a three-dimensional star and the legendary flight path of the ANT25 aircraft is displayed on the case back. On June 18, 1937, the crew of the ANT25 aircraft, led by V.P. CHKALOV, the first non-stop flight on the Moscow - North Pole - Vancouver route. This legendary flight of 8504 kilometers, which lasted 63 hours, immortalized the names of these Soviet pilots. This watch is limited to 330 pieces worldwide. Brand new watch, comes with box and manual.
