The newly reimagined Supermarine 300m and 300m Date models mark a bold evolution in Bremont’s iconic dive watch series. Now featuring a sleeker, slimmer case profile crafted from high-performance 904L stainless steel, these timepieces offer enhanced comfort without compromising on durability or strength.
The refined symmetrical case design incorporates integrated crown and bezel guards, ensuring both functional ease and added protection. These features safeguard against accidental impacts and maintain precise timing—ideal for professional or everyday wear.
At the centre of the design is a striking gradient dial, enhanced by an anodised aluminium knurled bezel with trapezoid indexes that extend seamlessly into a naval-inspired crosshair motif. The dial’s bold layout, paired with applied indexes and Super-LumiNova®, ensures exceptional visibility, even in the most challenging lighting conditions.
A completely redesigned 904L steel bracelet offers a luxurious wearing experience with fluid, ergonomic movement. Its infinity-shaped links, alternating between polished and satin finishes, conform comfortably to all wrist sizes. For added versatility, the watch is also available with a chevron-style performance rubber strap, inspired by military design, or a vintage brown leather strap with classic topstitching.
The engraved case back, featuring a map of the world’s oceans, is a subtle reminder of the Supermarine’s expedition-ready spirit—where technical excellence meets timeless aesthetics.
Built for the modern explorer, the Supermarine 300m is a masterclass in form, function, and enduring design.
