The watch and clock factory Penza (better known under their name “Zaria” in different spellings) was mainly known for their form movement, of which in then 1980s and 1990s large quantities were exportec into the west.
Hardly known however is the caliber Zaria 2002, a ladies’ watch movement with a diameter of only 20mm, which in its construction reminds a lot of swiss movements, such as the FHF 150 for example.
The base plate shows, that this movement, like all russian movements, was made for durability and reliability, since all important bearings contain rubies. The accurancy of fit of the individual parts is on need of improvement, you can see this at the ratches (first photo) and on the housing for the winding parts, which have a lot of play.
The Zaria 2002 uses the classical gear train with mainspring barrel, which drives the center minute wheel, followed by third wheel, seconds wheel at 6 o’clock and steel esacape wheel. At 6 o’clock, there’s the decentral seconds indication on the dial side.
The escape wheel has got compareatively small theeth compared to escape wheels of many other movements.
The screw-less anular balance is not shock protected and probably beats with 18000 A/h. Since the specimen shown here is broken, and there’s hardly any literature available, it remains with the guess.
Hoewer, it is dafe, that a pallet lever escapement of swiss type is used.
On the dial side, you see the very characteristical setting lever spring and a mix between old and new: The cap jewel plate for the non shock protected escape wheel balance looks old, the bew spring-loaded bearing for the setting lever looks modern.
