Bremont Watch Supermarine Chrono Bracelet SMARINECHRONO-BL-B. Bremont’s iconic Supermarine watch is given a sporty facelift as it delivers, for the very first time, immaculate chronometer certified chronograph complication. Since its release back in 2009, the Bremont Supermarine has been designed as an ‘amphibious watch’, a timepiece that not only links back to the British watch manufacturer’s long history with aviation but remains a beautiful and effective piece of diving equipment. The Bremont Supermarine Chrono continues this legacy with a formidable 43mm stainless steel case, scratch resistant PVD treated case barrel and chronometer certified movement, all extensively tested out in the field by elite military squadrons and top dive units around the world. As with all Bremont Supermarine watches before it, the new Supermarine Chrono is engineered using the brand’s legendary Trip-Tick case construction inclusive of a bi-directional rotating blue ceramic bezel with a laser engraved 24 hour scale, an exhibition case back and a screw in crown water resistant to 200 metres. Through the case back you can witness the immaculate construction of the BE-54AE automatic winding movement, a COSC certified calibre with a 42 hour power reserve, 25 jewels and a frequency of 28,800 bph. On the front end, the movement provides central hands for hours, minutes, GMT and chronograph seconds, three counters for running seconds, 12 hours and 30 minutes and a date window at 4.5H. Despite its impressive water resistance, the Bremont Supermarine Chrono measures to only a 15.8mm in thickness, a rare sight in a sports chronograph, and ensures optimal legibility on its smooth blue metal dial thanks to Superluminova accents on the central hands and indexes.
