The Bremont Supermarine 300m Date in bi-colour pairs a brown gradient dial with applied indexes infilled with vintage Super-LumiNova®, a brown dial ring with a printed minutes track, rose gold coloured hands and a date at 3 o'clock. An 18ct rose gold capped uni-directional dive bezel with a brown aluminium insert frames the dial.
The 40 mm uni-body case is made from 904L stainless steel, 12 mm deep with a 20 mm lug width, with an 18ct rose gold capped screw-in crown and a domed anti-reflective, scratch-resistant sapphire crystal. The screw-in, decorated closed case back helps keep it water resistant to 300 metres (980 feet).
Inside is the BE-92AV automatic movement (modified Sellita SW300-1 a) with 25 jewels, a 4 Hz beat and a 56-hour power reserve. Available on a quick-release stainless steel bracelet or a quick-release leather strap with cream side stitch.
