The Bremont Supermarine 300m GMT pairs a green gradient dial with applied indexes infilled with white Super-LumiNova®, a black dial ring with a printed minutes track and polished rhodium-plated hands. An orange-tipped GMT hand reads a second time zone against the green and black aluminium insert of the 24-hour bi-directional bezel, with a date at 3 o'clock.
The new 40 mm uni-body case is made from 904L stainless steel, 13 mm deep with a 20 mm lug width, under 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), and the watch head weighs about 78 g.
Inside is the BE-93-2AV automatic GMT movement (modified Sellita SW330-2) with 25 jewels, a 4 Hz beat and a 56-hour power reserve. Available on a bracelet or a black rubber strap.
