FIELD: physics.
SUBSTANCE: clock-face base has a body with a peripheral area, a central area and a holder placed on the peripheral area. The holder is in form of a front post, a back post and an insert cavity situated between the front post and the back post. The central area is formed by a front bottom and a rear bottom, facing each other to form a cavity. The front post is attached to the boundary of the rear bottom and is directed perpendicular to the rear bottom. The back post is attached to the boundary of the front bottom and is directed perpendicular to the front bottom. The front post and the back post are placed opposite each other, linked with each other and are configured for mutual flexible separation or the front post is configured for flexible separation, or the back post is configured for flexible separation.
EFFECT: realising the purpose, easier manufacture and use, broader functional capabilities of the clock-face.
