Design and Engineering

The Caliber 1186 is an evolution of the earlier Caliber 1185, with the addition of a rattrapante mechanism. This complication allows the chronograph to measure multiple elapsed times simultaneously, with the ability to stop and reset one of the chronograph hands without interrupting the ongoing timing. The movement retains the ultra-thin profile of its predecessor, measuring just 6.9 mm in height, making it one of the thinnest rattrapante chronographs ever produced.

The movement features a column-wheel chronograph mechanism with a vertical clutch, ensuring precise and smooth operation. The inclusion of 38 jewels helps reduce friction and enhance durability, while the Glucydur balance wheel provides stability and accuracy.

Applications in Watchmaking

The Caliber 1186 has been utilized in several high-end timepieces, particularly in luxury chronographs that prioritize both functionality and elegance. Notably, it has been featured in models by:

• Blancpain: Incorporated into their Villeret series, known for classic design and mechanical excellence.

• Omega: Utilized in select models, showcasing the movement's versatility and appeal among high-end manufacturers.

Legacy

The introduction of the Caliber 1186 marked a significant advancement in chronograph movement design, influencing the development of subsequent calibers. Its innovative rattrapante function combined with an ultra-thin profile set a new standard in mechanical watchmaking.

Conclusion

The Frédéric Piguet Caliber 1186 exemplifies the pinnacle of Swiss watchmaking excellence, combining the complexity of a rattrapante chronograph with the elegance of an ultra-thin design. Its application in luxury timepieces underscores its status as a preferred choice for high-end watches. For enthusiasts and collectors, the Caliber 1186 represents a harmonious blend of technical prowess and aesthetic elegance, solidifying its place in the legacy of fine horology.
