The Bulova 11UK0CB watch movement, utilized between 1960 to present, incorporates an excenter regulator for the stud carrier and a patented double-excenter winding mechanism with jewelled rollers. It features a rotor with jewel bearings for enhanced performance. Additionally, this movement employs an intermediate wheel to accommodate a large balance and maintain a low profile, without compromising robustness. Furthermore, its design allows the positioning of the seconds wheel either in the center or for a sub second, without requiring further modifications. This automatic movement also includes a sub second function.
