The Omega Seamaster Diver 300M Ref. 2254.50.00 in stainless steel with black dial and black aluminum bezel is a modern classic that perfectly blends professional diving functionality with timeless design, featuring a 41mm case with a mix of brushed and polished finishes that houses a striking black wave-pattern dial adorned with luminous hands and applied hour markers for exceptional underwater readability. Powered by Omega’s Caliber 1120 (based on the ETA 2892-A2), this automatic movement delivers reliable performance with 44-hour power reserve, while offering 300-meter water resistance through its screw-down crown and helium escape valve, making it a true professional diving instrument. The unidirectional rotating black aluminum bezel with engraved markings provides essential dive timing functionality, while the stainless steel bracelet with fold-over clasp and diver’s extension ensures secure comfort during extended wear. Designed for versatility, this Seamaster features a domed sapphire crystal with anti-reflective coating for enhanced clarity, and a solid caseback engraved with Omega’s seahorse emblem, maintaining the collection’s tool-watch heritage. The black wave-pattern dial creates a distinctive visual texture that catches the light beautifully, while the luminous markers and skeleton hands ensure optimal visibility in low-light conditions. Presented in Omega’s official packaging, this timepiece represents the perfect balance of professional diving capabilities and everyday wearability, offering collectors a robust yet refined watch that excels in both aquatic and urban environments. Key specifications: 41mm stainless steel case; black wave-pattern dial; Caliber 1120 automatic movement; 44-hour power reserve; stainless steel bracelet; 300m water resistance; unidirectional rotating bezel; sapphire crystal.
