This chronograph is a significant part of Omega&#8217;s history, representing the brand&#8217;s technical prowess and design excellence during a period of innovation in watchmaking. The 33.3 caliber, developed by Lemania (a sister company to Omega), was one of the first chronograph movements to feature a column-wheel mechanism, enhancing its precision and reliability.<\/p>\n<h2><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-11997 size-large\" src=\"https:\/\/www.vintagemasters.eu\/wp-content\/uploads\/2024\/05\/20240520_vintagemasters_hairspring-06-1024x683.jpg\" alt=\"omega ck987 33.3 chronograph closeup in hand\" width=\"1024\" height=\"683\" srcset=\"https:\/\/www.vintagemasters.eu\/wp-content\/uploads\/2024\/05\/20240520_vintagemasters_hairspring-06-1024x683.jpg 1024w, https:\/\/www.vintagemasters.eu\/wp-content\/uploads\/2024\/05\/20240520_vintagemasters_hairspring-06-300x200.jpg 300w, https:\/\/www.vintagemasters.eu\/wp-content\/uploads\/2024\/05\/20240520_vintagemasters_hairspring-06-768x512.jpg 768w, https:\/\/www.vintagemasters.eu\/wp-content\/uploads\/2024\/05\/20240520_vintagemasters_hairspring-06-1536x1024.jpg 1536w, https:\/\/www.vintagemasters.eu\/wp-content\/uploads\/2024\/05\/20240520_vintagemasters_hairspring-06-2048x1365.jpg 2048w, https:\/\/www.vintagemasters.eu\/wp-content\/uploads\/2024\/05\/20240520_vintagemasters_hairspring-06-900x600.jpg 900w, https:\/\/www.vintagemasters.eu\/wp-content\/uploads\/2024\/05\/20240520_vintagemasters_hairspring-06-675x450.jpg 675w, https:\/\/www.vintagemasters.eu\/wp-content\/uploads\/2024\/05\/20240520_vintagemasters_hairspring-06-600x400.jpg 600w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/h2>\n<h2>Design and Features<\/h2>\n<p>&#8211; <strong>Fall<\/strong>: The CK987 features a robust stainless steel case, measuring 37.5mm to 38mm in diameter. This size was considered large for the era, making the watch particularly notable and appealing to collectors today. The case design includes snap backs and oval pushers in early models.<br \/>\n&#8211; <strong>W\u00e4hlen Sie<\/strong>: The CK987 is known for its variety of dial configurations. The most common are black or silver dials with telemetric and tachymetric scales. These features were designed for precision timing and scientific use. Many dials have aged gracefully, developing a patina that adds to their vintage charm.<br \/>\n&#8211; <strong>Crystal<\/strong>: The watch uses a Plexiglas crystal, which was standard for the time and provides durability and clarity.<br \/>\n&#8211; <strong>Bewegung<\/strong>: The Omega caliber 33.3 CHRO is a manual-wind movement, operating at 18,000 vibrations per hour with 17 jewels. It includes a column-wheel chronograph mechanism, which was a hallmark of high-quality chronographs of that period.<\/p>\n<h2>Collectibility and Market Value<\/h2>\n<p>The Omega 33.3 Chronograph CK987 is highly collectible due to its historical significance and limited production numbers. Estimates suggest that around 14,000 units of the caliber 33.3 were produced over approximately 20 years. Prices for well-preserved examples can range from \u20ac10,000 to \u20ac20,000, with particularly rare or well-documented pieces commanding higher prices.<\/p>\n<div id=\"attachment_12003\" style=\"width: 1034px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-12003\" class=\"wp-image-12003 size-large\" src=\"https:\/\/www.vintagemasters.eu\/wp-content\/uploads\/2024\/05\/download-3-1024x486.png\" alt=\"Omega cal 33.3 ck987 black dial\" width=\"1024\" height=\"486\" srcset=\"https:\/\/www.vintagemasters.eu\/wp-content\/uploads\/2024\/05\/download-3-1024x486.png 1024w, https:\/\/www.vintagemasters.eu\/wp-content\/uploads\/2024\/05\/download-3-300x143.png 300w, https:\/\/www.vintagemasters.eu\/wp-content\/uploads\/2024\/05\/download-3-768x365.png 768w, https:\/\/www.vintagemasters.eu\/wp-content\/uploads\/2024\/05\/download-3-1536x730.png 1536w, https:\/\/www.vintagemasters.eu\/wp-content\/uploads\/2024\/05\/download-3-2048x973.png 2048w, https:\/\/www.vintagemasters.eu\/wp-content\/uploads\/2024\/05\/download-3-600x285.png 600w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><p id=\"caption-attachment-12003\" class=\"wp-caption-text\">Sold for \u20ac40.5k at Phillips.com<\/p><\/div>\n<h2>Comparison with Lemania and Tissot<\/h2>\n<p>Lemania, known for its robust and reliable movements, produced the 33.3 caliber used in the Omega CK987. Tissot, another brand under the same corporate umbrella as Omega and Lemania, also used Lemania movements in some of their chronographs during this period. However, Omega models typically fetch higher prices due to Omega&#8217;s stronger brand recognition and historical significance. While Tissot watches from the same era with similar movements are valued, they generally do not reach the same market levels as Omega counterparts.<\/p>\n<div id=\"attachment_12005\" style=\"width: 650px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-12005\" class=\"wp-image-12005 size-full\" src=\"https:\/\/www.vintagemasters.eu\/wp-content\/uploads\/2024\/05\/P1210344.jpeg\" alt=\"tissot omega 33.3 watch dial\" width=\"640\" height=\"640\" srcset=\"https:\/\/www.vintagemasters.eu\/wp-content\/uploads\/2024\/05\/P1210344.jpeg 640w, https:\/\/www.vintagemasters.eu\/wp-content\/uploads\/2024\/05\/P1210344-300x300.jpeg 300w, https:\/\/www.vintagemasters.eu\/wp-content\/uploads\/2024\/05\/P1210344-150x150.jpeg 150w, https:\/\/www.vintagemasters.eu\/wp-content\/uploads\/2024\/05\/P1210344-140x140.jpeg 140w, https:\/\/www.vintagemasters.eu\/wp-content\/uploads\/2024\/05\/P1210344-100x100.jpeg 100w, https:\/\/www.vintagemasters.eu\/wp-content\/uploads\/2024\/05\/P1210344-500x500.jpeg 500w, https:\/\/www.vintagemasters.eu\/wp-content\/uploads\/2024\/05\/P1210344-350x350.jpeg 350w, https:\/\/www.vintagemasters.eu\/wp-content\/uploads\/2024\/05\/P1210344-600x600.jpeg 600w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><p id=\"caption-attachment-12005\" class=\"wp-caption-text\">Image courtesy of timeline.watch<\/p><\/div>\n<h2>Production and Distribution<\/h2>\n<p>Production of the Omega 33.3 chronographs spanned from the late 1930s to the early 1950s, with the CK987 being one of the notable references.
