Design & Build Quality

The Omega Seamaster Diver 300M features a 42mm stainless steel case with a black ceramic bezel and a white enamel diving scale, ensuring durability and scratch resistance. The wave-patterned black ceramic dial adds depth and elegance, while the skeletonized hour and minute hands, coated with Super-LumiNova, enhance legibility in low-light conditions.
Furthermore, the iconic helium escape valve at 10 o’clock and the slightly domed sapphire crystal with anti-reflective treatment further emphasize its professional-grade build. The watch is paired with a robust stainless steel bracelet with Omega’s patented extendable clasp and diver’s extension, making it as functional as it is stylish.
Movement & Performance
The Seamaster runs on the Omega Co-Axial Master Chronometer Caliber 8800, a METAS-certified movement. This automatic movement offers a 55-hour power reserve and boasts an anti-magnetic resistance of up to 15,000 gauss, ensuring reliability even in extreme environments.
The movement operates at 25,200 vibrations per hour (3.5Hz) and features Omega’s Co-Axial escapement, reducing friction and enhancing longevity. Its accuracy and robustness make it a top contender in the luxury dive watch category.
Water Resistance & Dive Features
As a true dive watch, the Seamaster Diver 300M is water-resistant up to 300 meters (1,000 feet). The unidirectional ceramic bezel ensures precise dive timing, and the helium escape valve is a vital feature for saturation divers.
The screw-down crown enhances water resistance, while the Super-LumiNova coating on the hands, hour markers, and bezel pip ensures excellent readability underwater.
Comfort & Wearability
The 42mm Seamaster fits comfortably thanks to its balanced case design. The bracelet is solid yet ergonomic, and Omega’s fine-adjustment clasp provides a customized fit. For those who prefer variety, the watch is also available with a rubber strap, offering a more casual and lightweight option.
Price & Value
With a price range of $4,500–$6,000, the Omega Seamaster Diver 300M delivers outstanding value in the luxury dive watch market. It competes with the Rolex Submariner but at a more accessible price point while delivering similar, if not superior, technology and craftsmanship.
