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.

Lum-Tec gave up trying to fix my C2 with this movement, now I’m trying to find something that will fit the case/face/hands.

My latest 2427 is inside a CCCP Time Admiral Gorshalov, now unusually this has not only hacking (unheard of on most Soviet models) but lacks the date ring and has quickset date on the crown. I think this movement has one very unusual feature, the central shaft which carries the pinions is one long tube of ruby, looks super cool…
