Cheerfully whimsical yet mechanically profound, the Kolobok boasts a 40 mm stainless‑steel case with convex, gradient‑yellow lacquer dial evoking golden‑brown crust. Hours and minutes appear in expressive blue‑eyed “eyes,” while the smiling mouth serves as both day‑of‑week and moon‑phase indicator. Beneath beats Chaykin’s automatic K.18‑20 calibre (ETA‑2892‑A2 base, ~42 h reserve), crowned by a fairy‑tale rotor and sun‑shaped crown.
