About this watch

The Omega Constellation Co-Axial 38 is a masterpiece of luxury watchmaking, embodying elegance, precision, and sophistication. Founded in 1848, Omega has carved a niche in the industry with its innovative designs and precision engineering. The Constellation line, launched in 1952, embodies tradition with modernity. The paved diamond indexes and gem-set bezel give this watch a luxurious feel, while the white gold material adds an element of timelessness. At the core is the Omega caliber 8501 movement, renowned for its reliability and precision. With a gold rotor and 60-hour power reserve, it's designed for those who appreciate the finer things in life. The Co-Axial escapement enhances accuracy, reducing friction and ensuring longevity. This watch is not just a timekeeper; it's a piece of jewelry that can elevate any outfit. The gem-set bezel is a standout feature, dazzling in sunlight and catching the eye in dim light. The paved dial complements this with its elegant presentation, making time-telling an art form.
