Historical Context and Design Launched in 1937, the Omega CK987 was at the forefront of watchmaking technology during an era where precision timing was paramount. The 33.3 caliber movement, named for its diameter in millimeters, was a significant development for Omega, representing one of their earliest chronograph calibers. This movement was renowned for its robustness and accuracy, qualities that have endured through decades.

Monopusher Chronograph Functionality The CK987 features a monopusher chronograph, a sophisticated complication that allows all chronograph functions—start, stop, and reset—to be controlled via a single button integrated into the crown. This design not only enhances the watch’s aesthetic simplicity but also underscores Omega’s commitment to functional elegance.

Dial and Aesthetics The dial of the CK987 is a masterclass in vintage design. It sports a creamy patina that speaks to its age, adorned with intricate blue telemeter and tachymeter scales, which were essential for precise measurements in an era before digital instrumentation. The sub-dials, symmetrically positioned at 3 and 9 o’clock, provide a 30-minute counter and continuous seconds, respectively, adding to its balanced and utilitarian layout.

Case and Strap Encased in stainless steel, the CK987 measures approximately 37mm, a substantial size for its time that remains versatile and contemporary today. The case’s clean lines and polished finish enhance its timeless appeal. Paired with a supple, brown leather strap, the watch exudes a vintage charm that complements both formal and casual attire.

Movement and Mechanism At the heart of the CK987 is the manual-winding caliber 33.3, a movement revered for its engineering excellence. This caliber laid the groundwork for Omega’s future chronograph developments, boasting features such as a column wheel mechanism and a horizontal coupling system, ensuring reliable and smooth operation. The movement’s meticulous construction and finishing can be appreciated through its performance, even after more than eight decades.

Collectibility and Legacy The Omega CK987 is not just a watch; it is a piece of horological history. Its rarity, coupled with the historical significance of the 33.3 caliber, makes it a coveted piece among collectors. Each CK987 carries with it the legacy of Omega’s pioneering spirit and the enduring appeal of classic watchmaking.
