Omega De Ville Co‑Axial Service: The Omega De Ville Co‑Axial Chronometer has become synonymous with precision, luxury, and technical innovation. At the heart of this timepiece lies the Calibre 2202, a revolutionary movement incorporating Omega’s pioneering Co‑Axial escapement. Introduced in the early 2000s, this advancement significantly reduces friction in the gear train, ensuring greater longevity and reliability compared to traditional escapements.
We recently had the pleasure of servicing an Omega De Ville Co‑Axial Chronometer with the Calibre 2202. The owner, who had cherished the watch for years, noticed it was running poorly. As the automatic winding mechanism struggled to maintain enough power reserve, the owner resorted to daily hand winding. Unfortunately, this persistent manual winding eventually resulted in a broken winding pinion, necessitating professional intervention.


The Significance of the Omega Calibre 2202
The Omega Calibre 2202 is a self-winding mechanical movement, certified as a chronometer for its exceptional accuracy. A standout feature of this calibre is its Co‑Axial escapement, which reduces friction between the components responsible for regulating the watch’s timekeeping. This technology not only enhances accuracy over time but also extends the intervals between servicing, making it a landmark innovation in modern watchmaking.
The Calibre 2202 also features a free-sprung balance, offering greater stability and resistance to shocks or positional errors. With its sleek profile, the movement was perfectly suited for the elegant De Ville range, embodying both technical prowess and aesthetic refinement.


Assessing the Watch – Omega De Ville Co‑Axial Service
When the Omega De Ville arrived at our workshop, the watch was running far below its expected performance levels. Upon inspection, the broken winding pinion was immediately evident, a direct result of repeated manual winding. Additionally, the automatic winding mechanism showed signs of wear, with dirt and dried lubrication compromising its functionality.
Despite these issues, the Calibre 2202 remained in relatively good condition overall. The Co‑Axial escapement was intact, and there was no significant wear on the balance wheel or gear train. This was a testament to the durability of Omega’s engineering, even after years of less-than-optimal performance.


The Repair Process – Omega De Ville Co‑Axial Service
The service included a complete disassembly of the Calibre 2202. Each component was meticulously cleaned to remove old oil and debris, restoring the movement to its original condition. The broken winding pinion was replaced with a new OEM part, ensuring the watch could be safely hand-wound if needed in the future.
The automatic winding mechanism received special attention. Worn components were re-lubricated, and the rotor was checked for proper alignment and smooth operation. After reassembly, the movement was carefully calibrated to meet Omega’s stringent chronometer standards, ensuring both accuracy and reliability.
The case and bracelet were also cleaned and polished, restoring the watch’s exterior to its original luster. New gaskets were installed to restore water resistance and protect the movement from environmental factors.

Final Testing and Results
After servicing, the Omega De Ville Co‑Axial Chronometer underwent a multi-day testing process. The watch was monitored for timekeeping accuracy, power reserve, and automatic winding performance. The results were exceptional, with the Calibre 2202 delivering near-perfect accuracy and a fully restored power reserve.
Thanks to its innovative Co‑Axial escapement and robust design, this watch is now ready to provide its owner with many more years of reliable performance.
