The old Raketa caliber 2609 was a beautful, classically constructed mens’ size movement.
It contained a directly driven center second hand and also a directly driven center minute indication. The real speciality of that movement is the gold-toned screw balance with its breguet-type hairspring.
This detail was outside russia very expensive and only used in high-end watches and allows very good timing results.
For russian movements, Incabloc shock protections were unusual.
The features gold-tones balance - Incablock shock protections - breguet-overcoil - regulator arm were technically and aesthetically on the top range at the production time.
On the dial side, there’s of course a yoke winding system.
