This Kienzle 400-day clock, often fondly termed a "birthday clock" due to its remarkable annual winding requirement, stands as a testament to early 20th-century German craftsmanship. Encased in a clear glass dome that elegantly showcases its intricate Urania movement, this timepiece is both a marvel of engineering and a piece of history. Its dimensions, with a height of 27.5cm and a diameter of 18cm, make it a prominent yet delicate feature for any collector's display. Although currently non-operational, this clock, in visibly good condition, presents a fine opportunity for restoration by a skilled clockmaker, potentially increasing its value and charm. A collector's delight, this timepiece encapsulates the ingenuity and design prowess of the Kienzle factory's horological legacy.
