Reference 220.10.38.20.52.001 represents the Aqua Terra 150M at its most refined — a 38.5mm stainless steel case with a fixed bezel, scratch-resistant sapphire crystal, and a transparent case back that puts the automatic Co-Axial Master Chronometer movement on full display. The silver dial brings a clean, luminous character to the watch, while water resistance to 150m/500ft keeps it ready for life both on land and near the water.
The stainless steel bracelet features a brushed and polished finish and secures with a push-button folding clasp, lending the piece an everyday wearability without sacrificing elegance. The movement carries COSC chronometer certification, a testament to its precision timekeeping credentials.
This example is presented in new/unworn condition. No screw-in crown is fitted, and the case retains its characteristic round profile that has long defined the Aqua Terra line within Omega's broader Seamaster family.
