Self-winding mechanism (safety device against spring rewinding) East 2415.01 GOST 10733-98 The caliber is 24 mm. Frequency 19800 half-vibrations per hour Height (excluding the height of the second and minute tribs) 6.3 mm. 31 ruby stones Daily running at a temperature of 15-25 degrees within -20...+60 sec/ day Screw-down crown Power reserve of at least 33 hours Water resistance up to 20 atmospheres (immersion depth up to 200 meters) Glow-in-the-dark arrows and indexes The average service life of the watch mechanism is 10 years. The first Amphibian watches were made in 1967 at the Chistopol Watch Factory. All models of this series are equipped with two types of 24-gauge mechanisms. The movement 2415.01 is self-winding, the movement 2416B is equipped with automatic winding and an instant calendar. Models of 24-gauge mechanisms have the so-called Swiss anchor escapement system, steel anchor wheels and fork, supports on ruby stones, a winding spring made of a special precision alloy. All mechanisms undergo double assembly and testing control at the factory. Each Vostok watch has its own unique cipher consisting of six digits. The Vostok Amphibian 100822 watch has the following decoding: 10 - case number, 0 - case coating (uncoated), 822 - dial code. The amphibian is produced in seven hulls (06k, 09k, 10k, 11k, 12k, 42k, 71k). Amphibian watch dials are very diverse, as new models are released annually. The dials of the Commander's watch are also used in this series of watches. The main feature of the Amphibian watch is its high moisture resistance (immersion up to 200 meters) and high reliability in aggressive environments and harsh conditions. The glass lens in the Amphibian watch is thicker than that of a conventional watch (3 mm.), it is manufactured using a special technology that ensures tightness at high pressure. The amphibian was created especially for lovers of active recreation, free and active people.
