Omega Constellation Co-Axial 38 Stainless Steel / Red Gold / Brown

About this watch

The Omega Constellation Co-Axial 38 in Stainless Steel and Red Gold is a masterpiece of luxury watchmaking, boasting a rich history dating back to the 1950s. This stunning timepiece combines classic design with modern technology, featuring a sophisticated look that appeals to both casual and formal wearers. The round shape is timeless, embodying the essence of classic watch design while still feeling fresh. The 38 mm diameter strikes a perfect balance, making it large enough to be noticed but not so big that it feels cumbersome. The rich brown dial adds depth and character, making it a versatile piece that can be worn in various settings. The stick and dot indexes are classic yet modern, ensuring readability without overwhelming the design. The Dauphine hands glide gracefully across the dial, embodying precision and style. At the core of this exquisite timepiece lies the Omega caliber 8500 movement, a marvel of engineering featuring a Co-Axial escapement that enhances accuracy and reduces friction. With a power reserve of 60 hours, this automatic movement ensures that your watch keeps ticking even when you're not wearing it for a couple of days. The combination of stainless steel and red gold provides a striking appearance while enhancing the watch's durability. The sapphire crystal is scratch-resistant, ensuring that your watch remains pristine even in everyday wear situations. With a water resistance rating of 100 meters, this watch can handle splashes from daily life with ease.
