Originally introduced at Baselworld 2013 in rose gold, the Breguet Extra-Thin Automatic 5377 will be unveiled at Baselworld 2014 in platinum. The Tourbillon Extra-Thin automatic features an off-center tourbillon with a carriage in titanium. The movement, caliber 581DR, uses a silicon balance spring and an escapement made of silicon and anti-magnetic steel. Thanks to a high energy barrel the maximum power reserve is an impressive 90-hours. The movement is just under 3 mm thick, allowing for a case that is just 7 mm thick. Read more HERE.
