The 41 mm Seamaster 300 combines timeless design with cutting-edge technology. Crafted from polished and brushed stainless steel, the symmetrical case seamlessly integrates with a matching bracelet for a harmonious aesthetic. The varnished Summer Blue dial, with a gradient finish denoting water resistance, showcases OMEGA's attention to detail, featuring rhodium-plated hands, recessed hour markers, and open numerals filled with light blue Super-LumiNova for enhanced visibility.

The watch pays homage to its maritime legacy with a stamped commemorative Seamaster logo on the caseback, depicting Poseidon and two seahorses—a nod to both OMEGA's 1956 original design and its current iteration. Powering the Seamaster 300 is OMEGA's Co-Axial Master Chronometer calibre 8912, achieving the highest industry certification from the Swiss Federal Institute of Metrology (METAS).

With dimensions including a 21 mm lug width, 48.0 mm lug-to-lug distance, 13.9 mm thickness, and a 41 mm case diameter, the watch strikes a balanced blend of style, functionality, and durability. Water-resistant up to 30 bar (300 meters / 1000 feet), it embodies the spirit of exploration and reliability. Weighing approximately 156 g, the timepiece delivers a robust yet comfortable experience on the wrist, and the self-winding movement ensures a remarkable power reserve of 60 hours, further enhancing its appeal for those appreciating both form and function.
