Please see the photos for the assessment of watches. Runs well and keeps time accurately. Really watches look much better than in the photo. On the case there are some traces of time in the form of abrasions. Clocks for the fastest and highest-flying Soviet / Russian combat aircrafts (such as MiG-23, MiG-25, MiG-29 and Su-27)!
These clocks have been designed to withstand speeds of Mach 3 / 1800 mph (2900 km/h) and altitudes of up to 100,000 feet (30 km). These robust timepieces are built to keep time flawlessly while pulling 6G's! Built-in 27-volt heater ensures operation even at -60 °C (-75 °F).Each measures approximately 3 inches (8 cm) in diameter by 3 inches (8 cm) deep and feature a two-day / three-day precision clock movement with 26 jewels, inside an all-steel, dustproof and waterproof case. There is a factory seal on the glass! Fully operational and shows time precisely. All Antique watches are mechanical. Many repairs will not be cheap, as most likely they will require replacement of non-standard parts (unlike most late model watches). Antique watches should not be beaten or dropped - because repairs may be expensive. Antique watches are generally NOT waterproof. This is because waterproofing was not in general production until the middle of the 20th century for most watches. Therefore you should protect your antique watch from exposure to moisture. If your watch becomes wet it should be dried off quickly.
Carefully open all covers and use a hair drier to blow dry the movement, dial, covers, crown. This will reduce the amount of rust. If your watch becomes wet with any kind of salt water you should immediately immerse or spray your watch with fresh (no-salt) water to remove all the salt from the works before drying the watch completely. Any salt left in the watch will combine with moisture in the air to rust metal components of the movement, case etc. Winding any mechanical watch tight may break the mainspring.
If you can avoid it do not wind the watch hard. When adjusting the hands of your watch, move them in a clockwise direction only. Counter-clockwise adjustments may damage the movement. It is desirable to adjust the hands of your watch at the same time every day. An automatic or self-winding watch should be worn for at least 8 hours a day.
It is a mechanical watch in which the mainspring is wound automatically as a result of natural motion of the wearer's arm, to provide energy to run the watch, making manual winding unnecessary. If you must adjust counter-clockwise make it for small adjustments only i. Be careful and gentle when adjusting the movement speed (faster or slower). Don't make sharp movements, and don't touch other components in the movement especially the pendulum mechanism. Every 2-3 years it is necessary to service and oil vintage watches.
If the course of your watches is worsening and the accuracy of the reduction in the duration of the clock (autonomy) from one fully wound spring - it need a service. IF the watch is dirty - allow the watch to run down, don't wind it again until you have it serviced by a qualified watch repair expert. Dust will absorb and remove important lubricants and cause the movement pieces to wear down. To clean the case, dial and crystal you should use a cloth that does NOT leave fibers as these may get caught up in the movement.
Check with your Watch repair expert to get an appropriate cloth. Keep your antiques watch away from magnets. Strong magnetic fields may affect the accuracy of your watch since some vintage watches were made with iron based components in the movement. Most Cases and Covers are fine components and will not handle abuse well.
The watch should not be shaken, beaten, or stressed. Antique watches generally experience an error of up to 5-7 minutes a day. Any accuracy of +- 5 minutes is very good.Mechanical watch is not recommended to use for engage in extreme sports, and expose them to excessive vibration loads. Recoil force, which take on the clock, affect their reliability and precision. No matter how perfect was not anti-shock mechanism, there is always the chance of excessive load that details of the mechanism can not survive. It is not recommended to adjust, the date between 20.00 and 06.00, because at this time involved a mechanism for automatic adjustment date.
Translation pointers calendars manually in this position arrows may damage the mechanism. Date changes should be made, relegating pre-clockwise to lower sector of the dial for example, to position 6 (18.00) hours. In most cases, these watches contain the "start/stop" button and "reset" button.It is strongly recommended not to press the "reset" if the chronograph is running. Before you use the "Reset" button need to stop the chronograph by button "start/stop". Using the "reset" when running chronograph can damage the mechanism of most models of watches.
