Seamaster Aqua Terra 150M : 2503.52.00

The Omega Seamaster Aqua Terra 150M 2503.52.00, released in 2003, is a tribute to the Railmaster of the late fifties. This model features a stainless steel case with a diameter of 39.20 mm and a matching bracelet. The original Railmaster, introduced in 1957, was designed for professionals working in or around powerful electric currents and had a double antimagnetic case for protection. The contemporary Railmaster retains the exterior look of the original, with a matt black dial adorned with luminous Arabic numerals and triangular hour markers. The facetted Dauphine-style hands also have luminous inserts for excellent legibility. The watch is equipped with Omega's revolutionary Co-Axial Escapement movement, specifically the calibre 2403, which is self-winding and chronometer certified by COSC. It has a power reserve of 44 hours and features intricate finishing details such as Geneva wave décor and circular graining with gold-plated engravings. The Railmaster models are available in 41mm and 38mm case diameters, with options for a steel bracelet or brown or black leather straps. With water resistance up to 150 meters and a scratch-resistant sapphire crystal case back, this watch combines style and functionality seamlessly.
