The new Supermarine 300m and 300m Date models have been completely reimagined, showcasing a slimmer, more streamlined case profile crafted from 904L stainless steel—a premium alloy prized for its superior strength, corrosion resistance, and polished finish.
This newly engineered symmetrical case design integrates both crown and bezel guards, enhancing durability and offering added protection against accidental knocks, ensuring seamless performance in any environment.
A knurled-edge anodised aluminium bezel features distinct trapezoid indexes that extend fluidly onto the gradient dial, forming a naval-inspired crosshair motif that draws the eye to the center. Enhanced with applied indexes and Super-LumiNova®, the dial ensures excellent legibility in low-light conditions, making it as functional as it is visually striking.
Complementing the new case is an entirely redesigned 904L steel bracelet, offering a fluid, comfortable fit. Infinity-shaped links alternate between polished and satin finishes, delivering both elegance and adaptability to all wrist sizes. For those seeking alternative styles, the Supermarine 300m is also available with a chevron-patterned performance rubber strap or a vintage brown leather strap with refined topstitching.
A case back engraved with a map of the world’s oceans pays homage to Bremont’s heritage in maritime exploration—underscoring the spirit of adventure that defines this exceptional dive watch.
Robust yet refined, the Supermarine 300m is built for those who live boldly—above and below the surface.
