About this watch

The Omega Seamaster Aqua Terra 150M Master Chronometer 38 (Model: 220.23.38.20.03.001) is a stunning luxury watch that embodies the elegance and functionality of Omega's Aqua Terra collection. Introduced in 2017, this particular model features a round case with a diameter of 38.00 mm, perfect for those who prefer a more modest size. The blue dial boasts stick and dot indexes, providing a modern touch while ensuring legibility. The arrow hands sweep gracefully over the surface, adding to the overall elegance. The use of Sedna Gold, a special alloy developed by Omega, gives the watch a distinct hue that doesn’t fade over time. Coupled with stainless steel, this watch is not only beautiful but also durable. The sapphire glass is scratch-resistant, protecting the dial from daily wear and tear. At the core of the Aqua Terra is the Omega caliber 8900 movement, a technological marvel designed to be more reliable than its predecessors. This movement has received the prestigious METAS certification, guaranteeing precision and performance. The free-sprung balance with a silicon balance spring enhances the movement’s resistance to magnetic fields of over 15,000 Gauss. Additionally, the watch features a date function and a chronometer, combining style with functionality. One of the standout features is its water resistance up to 150 meters, perfect for those who lead an active lifestyle but also appreciate the finer things in life.
