The latest generation of the Supermarine 300m and 300m Date has been completely re-engineered, featuring a sleeker, slimmer profile crafted from premium 904L stainless steel—offering the perfect blend of strength, durability, and comfort.
With a newly designed symmetrical case silhouette, both crown and bezel guards are integrated to enhance practical functionality while safeguarding against accidental impacts or adjustments. This thoughtful redesign delivers improved ergonomics and resilience, ideal for both aquatic performance and everyday wear.
A bold gradient dial lies beneath an anodised aluminium knurled-edge bezel, with trapezoid indexes that seamlessly extend onto the dial, forming a naval-inspired crosshair motif that draws focus to the centre. Applied indexes and Super-LumiNova® ensure outstanding legibility in low light conditions, further elevating the watch’s utilitarian design.
Bremont introduces a fully re-engineered 904L stainless steel bracelet for this series, featuring infinity-shaped links with alternating polished and satin finishes. The flowing, ergonomic design offers a luxurious fit for all wrist sizes. Alternatively, the Supermarine 300m can be paired with a military-inspired chevron performance rubber strap or a vintage brown leather strap with refined topstitching for added versatility.
Finishing the case is an intricately engraved case back depicting a map of the world’s oceans—a tribute to Bremont’s deep-rooted connection to exploration and the sea.
The Supermarine 300m is a robust, stylish, and highly capable companion—engineered for those who demand performance and elegance in equal measure.
