Slava Caliber 2427

The Slava caliber 2427 is a vintage automatic watch movement that was made in Russia (USSR era).

Is it any good?

The Slava 2427 tends to be controversial in the watch community, with some being fans of the movement, and others pointing out its deficiencies. So much so, that even the main Wikipedia article for Slava was edited to remove content that is critical of the 2427 and similar calibers:

“Slava’s own mechanical movements feature two mainspring barrels coupled together with an idler gear. There are many versions of the movement including manual wind 2414 and 2428 (double date) and self-winding 2416 and 2427 (double date). The movements are quite sensitive to shocks due to thin balance staff. Other frequent problems include premature wear of rotor bearing and the clutch driving the hands (not a typical cannon pinion). Also the date indicator malfunctions are common. The movements are thus considered unreliable, especially compared to other Russian calibres.” –Source (“Slava Watches” on Wikipedia, edited on September 7, 2012)

Modern watches with this caliber:

Although the 2427 is a vintage calibre, it is also found in some modern Poljot-International brand watches such as the “Tsars of Russia” series; Poljot New Jaroslavl; Poljot Gorbatchov; Poljot Moscow Nights.

Modern 2427 movements are no longer made in Russia.
