The HMAF Supermarine 40 Date celebrates Bremont's enduring partnership with His Majesty's Armed Forces. Inspired by the Royal Navy and limited to 300 pieces, it features the official Navy heraldic badge at 6 o'clock and reflects the capability, purpose and human endeavour embodied by the British Armed Forces.

Inspired by the dark grey tones of naval vessels, the 40mm Supermarine is housed within a 904L steel case finished in an ultra-matt grey treatment and paired with a light grey vertical-gradient dial. A full ceramic bezel insert enhances durability, while hands and indexes feature next-generation Super-LumiNova® for exceptional legibility in low-light conditions.

Powered by the automatic BB64 movement with a 56-hour power reserve, the HMAF Supermarine 40 Date delivers 300m of water resistance and is fitted to a brushed grey nubuck leather strap with pin buckle. Purpose-built for performance, it remains true to Bremont's mission of creating durable British tool watches built for adventure and exploration.
