Among watchmakers, it is considered good practice to always balance wheels and other rotating parts.

Mechanics "dislike" unbalanced mechanisms. Since Konstantin Chaykin is constantly occupied with solving such problems, one day, he came up with a fun idea—to balance a wheel by giving it the shape of a smiley face.

Of course, the smiling "Happy Wheel" is very much in the spirit of the Wristmon design, so one day, such a wheel might well become part of the movement of a new model in this collection.
