Sports Watches: Omega’s Master Chronometer Calibers in Jewelry Watches
Omega’s dedication to incorporating cutting-edge Master Chronometer Calibers extends beyond its traditional models and into its ladies’ watches, including jewelry pieces. This move represents a notable leap in quality, as most luxury jewelry watches still use quartz movements. However, the Omega Seamaster Aqua Terra Jewellery houses the Co-Axial Master Chronometer Caliber 8807, an automatic movement certified by METAS, with an impressive 55-hour power reserve.

In-depth Analysis
Equipping a jewelry watch with such a high-level movement aligns with the current trend of precision and extreme chronometry in the watch industry. Today, precision is as valued as aesthetic beauty, and Omega excels by providing in-house movements that guarantee both performance and serviceability. Given the cost of luxury jewelry watches, which often feature high-grade diamonds or rubies, customers increasingly expect the same level of excellence in the watch’s mechanics as in its appearance.
Omega’s Caliber 8807, like all of its Master Chronometer movements, includes a Co-Axial escapement and a free-sprung balance wheel with a silicon balance spring. Being METAS-certified, it surpasses the standard COSC chronometer certification for accuracy, ensuring precision between 0 and +5 seconds per day, even under real-life wearing conditions. It also guarantees magnetic resistance up to 15,000 gauss, an assurance rarely found in jewelry watches, which are usually purchased more for their beauty than for their technical prowess.
Summary
Aesthetics are far from overlooked in this timepiece. The bezel and dial are adorned with diamonds, while 12 marquise-cut rubies serve as hour markers, all perfectly matched. Omega’s proprietary 18k rose gold alloy, Sedna gold, is used for the case and hands. The dial showcases a wave-inspired design, created using a combination of techniques: guilloché, wave-shaped gold appliques, and diamond settings, with gems gradually sized to fit the wave pattern. This intricate craftsmanship offers a more creative and sophisticated approach than merely covering the dial with diamonds. Additionally, the watch is water-resistant up to 150 meters, another feature rarely seen in luxury jewelry watches, offering both beauty and functionality in one elegant package.
