Omega 1120

Developed by Omega, the Caliber 1120 is an automatic chronometer movement recognized for its precision and utility within a range of the brand's timepieces. This caliber is also known by its alternative designations, 1120 and ETA 2892-A2, reflecting its foundational architecture. As an automatic movement, the Omega 1120 self-winds through the natural motion of the wearer's wrist, eliminating the need for manual winding during continuous wear. This mechanism is supported by 23 jewels, which serve to reduce friction at critical points within the gear train, thereby enhancing the movement's durability and contributing to its long-term accuracy. With a diameter of 25.6 mm, the caliber maintains a relatively compact profile, facilitating its integration into various watch case sizes without excessive bulk. The Omega 1120 operates at a frequency of 28,800 vibrations per hour (vph), equivalent to 4 Hz. This high beat rate contributes to the smooth, sweeping motion of the seconds hand and aids in maintaining stable timekeeping performance. A practical power reserve of 44 hours ensures that a fully wound watch can continue to function for nearly two full days when not worn, offering convenience for daily use. Furthermore, the movement's chronometer designation signifies that it has undergone rigorous testing and met specific standards for accuracy and reliability, providing the wearer with a high degree of confidence in its timekeeping capabilities. In terms of functionality, the Omega 1120 provides essential complications. It displays hours, minutes, and seconds, offering a complete and legible readout of the current time. The inclusion of a date complication adds practical utility for daily life, allowing the wearer to reference the current day of the month directly from the watch dial. This caliber powers a diverse selection of Omega timepieces, including models from both the elegant De Ville and robust Seamaster collections. Notable examples include the Omega De Ville Prestige Automatic 34.7 Yellow Gold / Champagne (Ref. 4600.11.02), the Omega De Ville Prestige Automatic 36.5 Stainless Steel / Silver / Bracelet (Ref. 4512.30.00), and the Omega De Ville Prestige Co-Axial 36.5 Stainless Steel / Silver (Ref. 4812.30.02). It also features in the Omega Seamaster 120M Automatic 36.25 Stainless Steel / Silver / Japan (Ref. 2501.33.00) and the Omega Seamaster 120M Automatic 36.25 Stainless Steel / Silver (Ref. 2501.31.00).
