Introducing Omega Aqua Terra (ref. 231.58.39.21.55.002), a refined timepiece that blends thoughtful design with reliable performance. A study in proportion and durability: crafted in yellow gold and measuring 38.5 mm in diameter, defined by a round silhouette, paired with a gem-set bezel. The caseback is open, and the crystal is sapphire, delivering water resistance to 15000 meters. The dial composition is deliberate and legible: a white tone, executed in mother of pearl, framed by gem-set indexes hour markers, and arrow hands. Beneath the caseback lies dependable performance: the 8501 caliber. First released in 2015. Comfort and balance define the wearing experience, making it an easy daily companion. Subtle transitions between textures elevate the overall impression. For buyers researching specifications and real-world impressions, this reference stands out for coherent design, dependable mechanics, and lasting relevance within modern horology.
