The Supermarine 300m Date in Black with Bracelet represents the quintessential dive watch—engineered for performance, built for durability, and designed with understated elegance. Crafted from premium 904L stainless steel, this timepiece delivers superior corrosion resistance and exceptional strength, making it ideal for both professional diving and everyday wear.
The robust 40mm case features a unidirectional rotating bezel with a black aluminum insert and precise timing markings, essential for underwater navigation. The deep black dial offers a striking contrast to the applied Super-LumiNova® indexes and hands, ensuring optimal legibility even in challenging lighting conditions.
At its heart lies a reliable automatic movement with a 50-hour power reserve, protected within the screw-down case construction that provides 300 meters of water resistance. The engraved case back, featuring a world ocean map, pays homage to the watch's maritime heritage.
Completing the package is Bremont's newly engineered 904L stainless steel bracelet with quick-release functionality and micro-adjustment capabilities, offering both comfort and convenience for any adventure.
