The Omega Calibre 1120: The Engine of Excellence
The Omega Calibre 1120 is the powerhouse behind all mechanical variations of the Omega Seamaster Professional 2254.50. This movement is not merely a timekeeping mechanism; it's a testament to Omega's commitment to precision and durability. A self-winding, chronometer-certified movement, the Calibre 1120 boasts a high level of accuracy, exceeding the standards set by COSC (Contrôle Officiel Suisse des Chronomètres). This certification guarantees that the movement has passed rigorous testing, ensuring its performance remains within strict tolerances.
The Calibre 1120’s architecture is based on the ETA 2892-A2, a highly regarded movement known for its robustness and reliability. However, Omega significantly enhanced this base movement, incorporating its own finishing, adjustments, and quality control processes. This results in a movement that is both accurate and visually stunning. The intricate details, visible through the exhibition caseback on some models, showcase the meticulous craftsmanship that goes into every Omega watch. The Geneva stripes, perlage, and blued screws are not merely decorative; they represent a dedication to excellence that permeates every aspect of the watch.
Key Features of the Calibre 1120:
* Self-winding: The movement automatically winds itself through the natural movement of the wearer's wrist, eliminating the need for manual winding.
* Chronometer-certified: The Calibre 1120 has passed rigorous COSC testing, guaranteeing its exceptional accuracy.
* High beat rate: While the exact beat rate isn't explicitly advertised as a marketing point, it shares the typical 28,800 bph of the ETA 2892-A2, contributing to its precise timekeeping.
* Power reserve: The Calibre 1120 generally offers a power reserve of approximately 44 hours. This means the watch will continue to run for a full two days after it's removed from the wrist.
* Date function: Most versions of the 2254.50 feature a date window at the 3 o'clock position, seamlessly integrated into the dial design.
