Case: The case is typically crafted from stainless steel, known for its durability and corrosion resistance. It usually measures around 40-42mm in diameter, making it suitable for a variety of wrist sizes. The case may feature a combination of polished and brushed finishes, enhancing its sporty yet elegant appearance. Dial: The dial design is focused on legibility, a hallmark of Ball watches. It often includes large, luminous hour markers and hands, coated with tritium gas tubes. Tritium provides constant illumination without needing an external light source, ensuring readability in low-light or dark conditions. The dial color is usually black, providing a stark contrast against the luminous markers for enhanced visibility. Crystal: The crystal protecting the dial is typically sapphire, known for its scratch resistance and clarity. It ensures the dial remains protected from daily wear and tear. Bezel: The bezel is often fixed (non-rotating) and may feature a coin-edge design for easy grip and manipulation. It complements the overall robust look of the watch. Case Back: The case back is likely solid and engraved with special markings related to the US Marine Corps, such as the emblem or motto, adding a unique touch to the watch. Water Resistance: The watch is designed to withstand water pressure to a certain depth, typically around 100 meters (330 feet). This makes it suitable for swimming, snorkeling, and other water-related activities, but not for deep-sea diving.
