The original Omega Seamaster Aqua Terra was introduced in 2002 as a successor to the earlier Seamaster 120 - a more elegant, less sporty version of Omega's dive watches. It was available in a wide variety of configurations, with either quartz or mechanical movements. Since then, the Aqua Terra has been revamped several times, with the present generation having been launched at BaselWorld 2017. 220.10.41.21.03.001 has a stainless steel case and matching bracelet. It is powered by the Master Co-Axial caliber 8900 and features a blue dial.
