Omega Seamaster Aqua Terra Marui Limited Edition, 39.2mm, Calibre 2500, automatic, Co-Axial escapement, chronometer-certified, 2503.60

The Omega Seamaster Aqua Terra Co-Axial Marui Limited Edition 2503.60 brings a distinctive red dial to the clean proportions of the first-generation Aqua Terra. Created for Japanese retailer Marui, this Japan-market edition pairs a 39.2mm stainless steel case with applied hour markers, contrasting hands and a date display at three o’clock. Its appeal lies in combining the Aqua Terra’s versatile design with a dial colour seldom encountered within this generation.

Power comes from the Omega Calibre 2500, a self-winding, chronometer-certified movement featuring the brand’s Co-Axial escapement. A significant movement in Omega’s adoption of Co-Axial technology, it combines everyday practicality with mechanical interest, visible through the exhibition caseback. Automatic winding and a straightforward date display make this an accessible watch to enjoy regularly.
