Paul Delury from Australia wrote a very detailed article about this watch. Nice photos.Lots of details and explanations on how to use it. He had the watch signed in Latin, though (even the caliber was signed in English, accoeding to the US import law.)
The translation of the days and months from Russian into English is here.
The watch has 19 jewel movements, the mechanism is mechanicalCaliber 2628 with 40 hours winding time.
Thickness : 11mm (to top of crystal)
The watch has two crowns, located at the 3 and 4 o’clock positions. The crown at 3 o’clock (see yellow arrow at right) handles the winding of the watch in the normal position, and a rather unique way of quick setting the Date display. By pulling this crown out against spring pressure, the date will advance one number for each activation. The crown at the 4 o’clock position (see white arrow at right) sets the perpetual calendar display.
