About this watch

The Omega Seamaster Aqua Terra 150M Co-Axial 30 is a visual masterpiece that marries stunning aesthetics with remarkable functionality. Its round shape and 30mm diameter make it a versatile choice, perfect for both casual and formal settings. The watch features a stunning grey dial that exudes sophistication, complemented by the warm tones of red gold and stainless steel. Crafted from a blend of stainless steel and red gold, the watch feels luxurious and durable. At the heart of this watch lies the Omega caliber 8520, an automatic movement known for its precision and reliability. With a frequency of 25,200 vibrations per hour, it ensures that you'll always be on time. This watch is packed with features, including hours, minutes, seconds, and date displays in analog format. The chronometer certification guarantees accuracy, while the Co-Axial escapement reduces friction between moving parts for improved accuracy and longevity. Its impressive water resistance of up to 150 meters makes it ideal for active individuals who enjoy swimming, snorkeling, or engaging in water sports. The grey dial features stick and dot indexes, providing a clean and uncluttered look. The sapphire crystal enhances visibility, reducing glare and ensuring clarity under various lighting conditions.
