About this watch

The Omega Seamaster Aqua Terra 150M Master Chronometer 38 Sedna Gold is a masterpiece that seamlessly blends elegance with athleticism. Crafted from 18K Sedna Gold, the watch exudes luxury from every angle. The gem-set bezel adds a touch of opulence, while the white mother-of-pearl (MOP) dial provides a beautiful contrast. With a round case diameter of 38.00 mm and a lug width of 19.00 mm, the watch strikes a perfect balance between boldness and wearability. The open case back allows enthusiasts to admire the intricate movement within, featuring the Omega caliber 8801 with Co-Axial escapement and Master Chronometer certification process approved by METAS. This self-winding movement is equipped with a power reserve of 55 hours and resistant to magnetic fields reaching up to 15,000 gauss. The sapphire crystal is scratch-resistant and offers excellent clarity, ensuring that your watch remains pristine over time. The 18K Sedna Gold case adds a layer of protection while maintaining a luxurious aesthetic.
